+ <title>Serial Peripheral Interface (SPI)</title>
+ <para>
+ SPI is the "Serial Peripheral Interface", widely used with
+ embedded systems because it is a simple and efficient
+ interface: basically a multiplexed shift register.
+ Its three signal wires hold a clock (SCK, often in the range
+ of 1-20 MHz), a "Master Out, Slave In" (MOSI) data line, and
+ a "Master In, Slave Out" (MISO) data line.
+ SPI is a full duplex protocol; for each bit shifted out the
+ MOSI line (one per clock) another is shifted in on the MISO line.
+ Those bits are assembled into words of various sizes on the
+ way to and from system memory.
+ An additional chipselect line is usually active-low (nCS);
+ four signals are normally used for each peripheral, plus
+ sometimes an interrupt.
+ </para>
+ <para>
+ The SPI bus facilities listed here provide a generalized
+ interface to declare SPI busses and devices, manage them
+ according to the standard Linux driver model, and perform
+ input/output operations.
+ At this time, only "master" side interfaces are supported,
+ where Linux talks to SPI peripherals and does not implement
+ such a peripheral itself.
+ (Interfaces to support implementing SPI slaves would
+ necessarily look different.)
+ </para>
+ <para>
+ The programming interface is structured around two kinds of driver,
+ and two kinds of device.
+ A "Controller Driver" abstracts the controller hardware, which may
+ be as simple as a set of GPIO pins or as complex as a pair of FIFOs
+ connected to dual DMA engines on the other side of the SPI shift
+ register (maximizing throughput). Such drivers bridge between
+ whatever bus they sit on (often the platform bus) and SPI, and
+ expose the SPI side of their device as a
+ <structname>struct spi_master</structname>.
+ SPI devices are children of that master, represented as a
+ <structname>struct spi_device</structname> and manufactured from
+ <structname>struct spi_board_info</structname> descriptors which
+ are usually provided by board-specific initialization code.
+ A <structname>struct spi_driver</structname> is called a
+ "Protocol Driver", and is bound to a spi_device using normal
+ driver model calls.
+ </para>
+ <para>
+ The I/O model is a set of queued messages. Protocol drivers
+ submit one or more <structname>struct spi_message</structname>
+ objects, which are processed and completed asynchronously.
+ (There are synchronous wrappers, however.) Messages are
+ built from one or more <structname>struct spi_transfer</structname>
+ objects, each of which wraps a full duplex SPI transfer.
+ A variety of protocol tweaking options are needed, because
+ different chips adopt very different policies for how they
+ use the bits transferred with SPI.

+Deferred IO
+-----------
+
+Deferred IO is a way to delay and repurpose IO. It uses host memory as a
+buffer and the MMU pagefault as a pretrigger for when to perform the device
+IO. The following example may be a useful explaination of how one such setup
+works:
+
+- userspace app like Xfbdev mmaps framebuffer
+- deferred IO and driver sets up nopage and page_mkwrite handlers
+- userspace app tries to write to mmaped vaddress
+- we get pagefault and reach nopage handler
+- nopage handler finds and returns physical page
+- we get page_mkwrite where we add this page to a list
+- schedule a workqueue task to be run after a delay
+- app continues writing to that page with no additional cost. this is
+ the key benefit.
+- the workqueue task comes in and mkcleans the pages on the list, then
+ completes the work associated with updating the framebuffer. this is
+ the real work talking to the device.
+- app tries to write to the address (that has now been mkcleaned)
+- get pagefault and the above sequence occurs again
+
+As can be seen from above, one benefit is roughly to allow bursty framebuffer
+writes to occur at minimum cost. Then after some time when hopefully things
+have gone quiet, we go and really update the framebuffer which would be
+a relatively more expensive operation.
+
+For some types of nonvolatile high latency displays, the desired image is
+the final image rather than the intermediate stages which is why it's okay
+to not update for each write that is occuring.
+
+It may be the case that this is useful in other scenarios as well. Paul Mundt
+has mentioned a case where it is beneficial to use the page count to decide
+whether to coalesce and issue SG DMA or to do memory bursts.
+
+Another one may be if one has a device framebuffer that is in an usual format,
+say diagonally shifting RGB, this may then be a mechanism for you to allow
+apps to pretend to have a normal framebuffer but reswizzle for the device
+framebuffer at vsync time based on the touched pagelist.
+
+How to use it: (for applications)
+---------------------------------
+No changes needed. mmap the framebuffer like normal and just use it.
+
+How to use it: (for fbdev drivers)
+----------------------------------
+The following example may be helpful.
+
+1. Setup your structure. Eg:
+
+static struct fb_deferred_io hecubafb_defio = {
+ .delay = HZ,
+ .deferred_io = hecubafb_dpy_deferred_io,
+};
+
+The delay is the minimum delay between when the page_mkwrite trigger occurs
+and when the deferred_io callback is called. The deferred_io callback is
+explained below.
+
+2. Setup your deferred IO callback. Eg:
+static void hecubafb_dpy_deferred_io(struct fb_info *info,
+ struct list_head *pagelist)
+
+The deferred_io callback is where you would perform all your IO to the display
+device. You receive the pagelist which is the list of pages that were written
+to during the delay. You must not modify this list. This callback is called
+from a workqueue.
+
+3. Call init
+ info->fbdefio = &hecubafb_defio;
+ fb_deferred_io_init(info);
+
+4. Call cleanup
+ fb_deferred_io_cleanup(info);

+Debugging suspend and resume
+ (C) 2007 Rafael J. Wysocki <rjw@sisk.pl>, GPL
+
+1. Testing suspend to disk (STD)
+
+To verify that the STD works, you can try to suspend in the "reboot" mode:
+
+# echo reboot > /sys/power/disk
+# echo disk > /sys/power/state
+
+and the system should suspend, reboot, resume and get back to the command prompt
+where you have started the transition. If that happens, the STD is most likely
+to work correctly, but you need to repeat the test at least a couple of times in
+a row for confidence. This is necessary, because some problems only show up on
+a second attempt at suspending and resuming the system. You should also test
+the "platform" and "shutdown" modes of suspend:
+
+# echo platform > /sys/power/disk
+# echo disk > /sys/power/state
+
+or
+
+# echo shutdown > /sys/power/disk
+# echo disk > /sys/power/state
+
+in which cases you will have to press the power button to make the system
+resume. If that does not work, you will need to identify what goes wrong.
+
+a) Test mode of STD
+
+To verify if there are any drivers that cause problems you can run the STD
+in the test mode:
+
+# echo test > /sys/power/disk
+# echo disk > /sys/power/state
+
+in which case the system should freeze tasks, suspend devices, disable nonboot
+CPUs (if any), wait for 5 seconds, enable nonboot CPUs, resume devices, thaw
+tasks and return to your command prompt. If that fails, most likely there is
+a driver that fails to either suspend or resume (in the latter case the system
+may hang or be unstable after the test, so please take that into consideration).
+To find this driver, you can carry out a binary search according to the rules:
+- if the test fails, unload a half of the drivers currently loaded and repeat
+(that would probably involve rebooting the system, so always note what drivers
+have been loaded before the test),
+- if the test succeeds, load a half of the drivers you have unloaded most
+recently and repeat.
+
+Once you have found the failing driver (there can be more than just one of
+them), you have to unload it every time before the STD transition. In that case
+please make sure to report the problem with the driver.
+
+It is also possible that a cycle can still fail after you have unloaded
+all modules. In that case, you would want to look in your kernel configuration
+for the drivers that can be compiled as modules (testing again with them as
+modules), and possibly also try boot time options such as "noapic" or "noacpi".
+
+b) Testing minimal configuration
+
+If the test mode of STD works, you can boot the system with "init=/bin/bash"
+and attempt to suspend in the "reboot", "shutdown" and "platform" modes. If
+that does not work, there probably is a problem with a driver statically
+compiled into the kernel and you can try to compile more drivers as modules,
+so that they can be tested individually. Otherwise, there is a problem with a
+modular driver and you can find it by loading a half of the modules you normally
+use and binary searching in accordance with the algorithm:
+- if there are n modules loaded and the attempt to suspend and resume fails,
+unload n/2 of the modules and try again (that would probably involve rebooting
+the system),
+- if there are n modules loaded and the attempt to suspend and resume succeeds,
+load n/2 modules more and try again.
+
+Again, if you find the offending module(s), it(they) must be unloaded every time
+before the STD transition, and please report the problem with it(them).
+
+c) Advanced debugging
+
+In case the STD does not work on your system even in the minimal configuration
+and compiling more drivers as modules is not practical or some modules cannot
+be unloaded, you can use one of the more advanced debugging techniques to find
+the problem. First, if there is a serial port in your box, you can set the
+CONFIG_DISABLE_CONSOLE_SUSPEND kernel configuration option and try to log kernel
+messages using the serial console. This may provide you with some information
+about the reasons of the suspend (resume) failure. Alternatively, it may be
+possible to use a FireWire port for debugging with firescope
+(ftp://ftp.firstfloor.org/pub/ak/firescope/). On i386 it is also possible to
+use the PM_TRACE mechanism documented in Documentation/s2ram.txt .
+
+2. Testing suspend to RAM (STR)
+
+To verify that the STR works, it is generally more convenient to use the s2ram
+tool available from http://suspend.sf.net and documented at
+http://en.opensuse.org/s2ram . However, before doing that it is recommended to
+carry out the procedure described in section 1.
+
+Assume you have resolved the problems with the STD and you have found some
+failing drivers. These drivers are also likely to fail during the STR or
+during the resume, so it is better to unload them every time before the STR
+transition. Now, you can follow the instructions at
+http://en.opensuse.org/s2ram to test the system, but if it does not work
+"out of the box", you may need to boot it with "init=/bin/bash" and test
+s2ram in the minimal configuration. In that case, you may be able to search
+for failing drivers by following the procedure analogous to the one described in
+1b). If you find some failing drivers, you will have to unload them every time
+before the STR transition (ie. before you run s2ram), and please report the
+problems with them.

+Testing suspend and resume support in device drivers
+ (C) 2007 Rafael J. Wysocki <rjw@sisk.pl>, GPL
+
+1. Preparing the test system
+
+Unfortunately, to effectively test the support for the system-wide suspend and
+resume transitions in a driver, it is necessary to suspend and resume a fully
+functional system with this driver loaded. Moreover, that should be done
+several times, preferably several times in a row, and separately for the suspend
+to disk (STD) and the suspend to RAM (STR) transitions, because each of these
+cases involves different ordering of operations and different interactions with

+Of course, for this purpose the test system has to be known to suspend and

+more information about the debugging of suspend/resume functionality.
+
+2. Testing the driver
+
+Once you have resolved the suspend/resume-related problems with your test system
+without the new driver, you are ready to test it:
+
+a) Build the driver as a module, load it and try the STD in the test mode (see:
+Documents/power/basic-pm-debugging.txt, 1a)).
+
+b) Load the driver and attempt to suspend to disk in the "reboot", "shutdown"
+and "platform" modes (see: Documents/power/basic-pm-debugging.txt, 1).
+
+c) Compile the driver directly into the kernel and try the STD in the test mode.
+
+d) Attempt to suspend to disk with the driver compiled directly into the kernel
+in the "reboot", "shutdown" and "platform" modes.
+
+e) Attempt to suspend to RAM using the s2ram tool with the driver loaded (see:
+Documents/power/basic-pm-debugging.txt, 2). As far as the STR tests are
+concerned, it should not matter whether or not the driver is built as a module.
+
+Each of the above tests should be repeated several times and the STD tests
+should be mixed with the STR tests. If any of them fails, the driver cannot be
+regarded as suspend/resume-safe.

+Some reasons you might want to use this programming interface include:
+
+ * Prototyping in an environment that's not crash-prone; stray pointers
+ in userspace won't normally bring down any Linux system.
+
+ * Developing simple protocols used to talk to microcontrollers acting
+ as SPI slaves, which you may need to change quite often.
+
+Of course there are drivers that can never be written in userspace, because
+they need to access kernel interfaces (such as IRQ handlers or other layers
+of the driver stack) that are not accessible to userspace.
+
+
+DEVICE CREATION, DRIVER BINDING
+===============================
+The simplest way to arrange to use this driver is to just list it in the
+spi_board_info for a device as the driver it should use: the "modalias"
+entry is "spidev", matching the name of the driver exposing this API.
+Set up the other device characteristics (bits per word, SPI clocking,
+chipselect polarity, etc) as usual, so you won't always need to override
+them later.
+
+(Sysfs also supports userspace driven binding/unbinding of drivers to
+devices. That mechanism might be supported here in the future.)
+
+When you do that, the sysfs node for the SPI device will include a child
+device node with a "dev" attribute that will be understood by udev or mdev.
+(Larger systems will have "udev". Smaller ones may configure "mdev" into
+busybox; it's less featureful, but often enough.) For a SPI device with
+chipselect C on bus B, you should see:
+
+ /dev/spidevB.C ... character special device, major number 153 with
+ a dynamically chosen minor device number. This is the node
+ that userspace programs will open, created by "udev" or "mdev".
+
+ /sys/devices/.../spiB.C ... as usual, the SPI device node will
+ be a child of its SPI master controller.
+
+ /sys/class/spidev/spidevB.C ... created when the "spidev" driver
+ binds to that device. (Directory or symlink, based on whether
+ or not you enabled the "deprecated sysfs files" Kconfig option.)
+
+Do not try to manage the /dev character device special file nodes by hand.
+That's error prone, and you'd need to pay careful attention to system
+security issues; udev/mdev should already be configured securely.
+
+If you unbind the "spidev" driver from that device, those two "spidev" nodes
+(in sysfs and in /dev) should automatically be removed (respectively by the
+kernel and by udev/mdev). You can unbind by removing the "spidev" driver
+module, which will affect all devices using this driver. You can also unbind
+by having kernel code remove the SPI device, probably by removing the driver
+for its SPI controller (so its spi_master vanishes).
+
+Since this is a standard Linux device driver -- even though it just happens
+to expose a low level API to userspace -- it can be associated with any number
+of devices at a time. Just provide one spi_board_info record for each such
+SPI device, and you'll get a /dev device node for each device.
+
+
+BASIC CHARACTER DEVICE API
+==========================
+Normal open() and close() operations on /dev/spidevB.D files work as you
+would expect.
+
+Standard read() and write() operations are obviously only half-duplex, and
+the chipselect is deactivated between those operations. Full-duplex access,
+and composite operation without chipselect de-activation, is available using
+the SPI_IOC_MESSAGE(N) request.
+
+Several ioctl() requests let your driver read or override the device's current
+settings for data transfer parameters:
+
+ SPI_IOC_RD_MODE, SPI_IOC_WR_MODE ... pass a pointer to a byte which will
+ return (RD) or assign (WR) the SPI transfer mode. Use the constants
+ SPI_MODE_0..SPI_MODE_3; or if you prefer you can combine SPI_CPOL
+ (clock polarity, idle high iff this is set) or SPI_CPHA (clock phase,
+ sample on trailing edge iff this is set) flags.
+
+ SPI_IOC_RD_LSB_FIRST, SPI_IOC_WR_LSB_FIRST ... pass a pointer to a byte
+ which will return (RD) or assign (WR) the bit justification used to
+ transfer SPI words. Zero indicates MSB-first; other values indicate
+ the less common LSB-first encoding. In both cases the specified value
+ is right-justified in each word, so that unused (TX) or undefined (RX)
+ bits are in the MSBs.
+
+ SPI_IOC_RD_BITS_PER_WORD, SPI_IOC_WR_BITS_PER_WORD ... pass a pointer to
+ a byte which will return (RD) or assign (WR) the number of bits in
+ each SPI transfer word. The value zero signifies eight bits.
+
+ SPI_IOC_RD_MAX_SPEED_HZ, SPI_IOC_WR_MAX_SPEED_HZ ... pass a pointer to a
+ u32 which will return (RD) or assign (WR) the maximum SPI transfer
+ speed, in Hz. The controller can't necessarily assign that specific
+ clock speed.
+
+NOTES:
+
+ - At this time there is no async I/O support; everything is purely
+ synchronous.
+
+ - There's currently no way to report the actual bit rate used to
+ shift data to/from a given device.
+
+ - From userspace, you can't currently change the chip select polarity;
+ that could corrupt transfers to other devices sharing the SPI bus.
+ Each SPI device is deselected when it's not in active use, allowing
+ other drivers to talk to other devices.
+
+ - There's a limit on the number of bytes each I/O request can transfer
+ to the SPI device. It defaults to one page, but that can be changed
+ using a module parameter.
+
+ - Because SPI has no low-level transfer acknowledgement, you usually
+ won't see any I/O errors when talking to a non-existent device.
+
+
+FULL DUPLEX CHARACTER DEVICE API
+================================
+
+See the sample program below for one example showing the use of the full
+duplex programming interface. (Although it doesn't perform a full duplex
+transfer.) The model is the same as that used in the kernel spi_sync()
+request; the individual transfers offer the same capabilities as are
+available to kernel drivers (except that it's not asynchronous).
+
+The example shows one half-duplex RPC-style request and response message.
+These requests commonly require that the chip not be deselected between
+the request and response. Several such requests could be chained into
+a single kernel request, even allowing the chip to be deselected after
+each response. (Other protocol options include changing the word size
+and bitrate for each transfer segment.)
+
+To make a full duplex request, provide both rx_buf and tx_buf for the
+same transfer. It's even OK if those are the same buffer.

+ * linux/drivers/video/hecubafb.c -- FB driver for Hecuba controller
+ *
+ * Copyright (C) 2006, Jaya Kumar
+ * This work was sponsored by CIS(M) Sdn Bhd
+ *
+ * This file is subject to the terms and conditions of the GNU General Public
+ * License. See the file COPYING in the main directory of this archive for
+ * more details.
+ *
+ * Layout is based on skeletonfb.c by James Simmons and Geert Uytterhoeven.
+ * This work was possible because of apollo display code from E-Ink's website
+ * http://support.eink.com/community
+ * All information used to write this code is from public material made
+ * available by E-Ink on its support site. Some commands such as 0xA4
+ * were found by looping through cmd=0x00 thru 0xFF and supplying random
+ * values. There are other commands that the display is capable of,
+ * beyond the 5 used here but they are more complex.
+ *
+ * This driver is written to be used with the Hecuba display controller
+ * board, and tested with the EInk 800x600 display in 1 bit mode.
+ * The interface between Hecuba and the host is TTL based GPIO. The
+ * GPIO requirements are 8 writable data lines and 6 lines for control.
+ * Only 4 of the controls are actually used here but 6 for future use.
+ * The driver requires the IO addresses for data and control GPIO at
+ * load time. It is also possible to use this display with a standard
+ * PC parallel port.
+ *
+ * General notes:
+ * - User must set hecubafb_enable=1 to enable it
+ * - User must set dio_addr=0xIOADDR cio_addr=0xIOADDR c2io_addr=0xIOADDR

+ * updating the accessed and modified bits in the page table tree.
+ */
+
+/*
+ * The PowerPC MPC8xx uses a TLB with hardware assisted, software tablewalk.
+ * We also use the two level tables, but we can put the real bits in them
+ * needed for the TLB and tablewalk. These definitions require Mx_CTR.PPM = 0,
+ * Mx_CTR.PPCS = 0, and MD_CTR.TWAM = 1. The level 2 descriptor has
+ * additional page protection (when Mx_CTR.PPCS = 1) that allows TLB hit
+ * based upon user/super access. The TLB does not have accessed nor write
+ * protect. We assume that if the TLB get loaded with an entry it is
+ * accessed, and overload the changed bit for write protect. We use
+ * two bits in the software pte that are supposed to be set to zero in
+ * the TLB entry (24 and 25) for these indicators. Although the level 1
+ * descriptor contains the guarded and writethrough/copyback bits, we can
+ * set these at the page level since they get copied from the Mx_TWC
+ * register when the TLB entry is loaded. We will use bit 27 for guard, since
+ * that is where it exists in the MD_TWC, and bit 26 for writethrough.
+ * These will get masked from the level 2 descriptor at TLB load time, and
+ * copied to the MD_TWC before it gets loaded.
+ * Large page sizes added. We currently support two sizes, 4K and 8M.
+ * This also allows a TLB hander optimization because we can directly
+ * load the PMD into MD_TWC. The 8M pages are only used for kernel
+ * mapping of well known areas. The PMD (PGD) entries contain control
+ * flags in addition to the address, so care must be taken that the
+ * software no longer assumes these are only pointers.
+ */

+ * hardware-managed, 4-entry, fully-associative TLB which serves as a

+ * struct spi_ioc_transfer - describes a single SPI transfer
+ * @tx_buf: Holds pointer to userspace buffer with transmit data, or null.
+ * If no data is provided, zeroes are shifted out.
+ * @rx_buf: Holds pointer to userspace buffer for receive data, or null.
+ * @len: Length of tx and rx buffers, in bytes.
+ * @speed_hz: Temporary override of the device's bitrate.
+ * @bits_per_word: Temporary override of the device's wordsize.
+ * @delay_usecs: If nonzero, how long to delay after the last bit transfer
+ * before optionally deselecting the device before the next transfer.
+ * @cs_change: True to deselect device before starting the next transfer.
+ *
+ * This structure is mapped directly to the kernel spi_transfer structure;
+ * the fields have the same meanings, except of course that the pointers
+ * are in a different address space (and may be of different sizes in some
+ * cases, such as 32-bit i386 userspace over a 64-bit x86_64 kernel).
+ * Zero-initialize the structure, including currently unused fields, to
+ * accomodate potential future updates.
+ *
+ * SPI_IOC_MESSAGE gives userspace the equivalent of kernel spi_sync().
+ * Pass it an array of related transfers, they'll execute together.
+ * Each transfer may be half duplex (either direction) or full duplex.
+ *
+ * struct spi_ioc_transfer mesg[4];

+ * status = ioctl(fd, SPI_IOC_MESSAGE(4), mesg);
+ *
+ * So for example one transfer might send a nine bit command (right aligned
+ * in a 16-bit word), the next could read a block of 8-bit data before
+ * terminating that command by temporarily deselecting the chip; the next
+ * could send a different nine bit command (re-selecting the chip), and the
+ * last transfer might write some register values.
