2010-02-04davinci: build list of unused EDMA events dynamicallySudhakar Rajashekhara
Currently, the edma_noevent list is passed from platform data. But on some architectures, there will be many EDMA channels which will not be used at all. This patch scans all the platform devices and then builds a list of events which are not being used. The unused event list will be used to allocate EDMA channels in case of EDMA_CHANNEL_ANY usage instead of the edma_noevent being used earlier for this purpose.

2010-02-04davinci: add support for CDCE949 clock synthesizerNageswari Srinivasan
This patch adds support for TI's CDCE949 - a clock synthesizer with 4 PLLs and 9 outputs. It is used on DM6467 EVM. On the EVM, it generates clocks required for VPIF, TSIF and Audio modules. This patch adds it as part of the DaVinci clock framework. Testing: The various frequency outputs on Y1 have been tested using a out-of-tree VPIF video driver supporting HD video. The register values for Y5 frequency outputs have been derived from TSIF driver sources in MontaVista LSP kernel, but actual output has not been tested for lack of TSIF driver which actually works on the latest kernel.

Currently only RTC alarm based wakeup is supported. Support for wakeup based on external event will be added as later improvements.

2010-02-04davinci: add power management supportSekhar Nori
This patch adds core power management (suspend-to-RAM) support for DaVinci SoCs. The code depends on the the "deepsleep" feature to suspend the SoC and saves power by gating the input clock. The wakeup can be based on an external event as supported by the SoC. Assembly code (in sleep.S) is added to aid gating DDR2 clocks. Code doing this work should not be accessing DDR2. The assembly code is relocated to SRAM by the code in pm.c The support has been validated on DA850/OMAP-L138 only though the code is (hopefully) generic enough that other SoCs supporting deepsleep feature simply requires SoC specific code to start using this driver. Note that all the device drivers don't support suspend/resume still and are being worked on. Signed-off-by: Sekhar Nori <nsekhar@ti.com> Signed-off-by: Kevin Hilman <khilman@deeprootsystems.com>

2010-02-04davinci: add support for DM6467T EVMSekhar Nori
DM6467T (T for Turbo) is a newer and faster DM6467 part from TI. The new part supports 1080p video and has the ARM running at 495MHz. More SoC information: http://focus.ti.com/docs/prod/folders/print/tms320dm6467t.html Spectrum Digital, Inc has a new EVM for this part. It is _mostly_ same as the older DM6467 EVM except for a 33MHz crystal input and THS8200 video encoder for 1080p support. The meat of this patch is dedicated to initializing the crystal frequency from EVM board file. Additional notes: I did consider some alternative ways to make the crystal input board specific including - (1) having board code initialize the crystal frequency using the first member of soc_info->cpu_clks array (2) introducing a new ref_clk_rate member in soc_info structure. But, the current way seems to be the simplest and least intruding considering that both the clock array and SoC info structure are actually private to the SoC file. Also the fact that davinci_common_init() initializes both the soc_info and clocks in one go. Signed-off-by: Sekhar Nori <nsekhar@ti.com> Signed-off-by: Kevin Hilman <khilman@deeprootsystems.com>

Leave a comment explaining the constant value of 27Mhz used in include/mach/timex.h for all DaVinci platforms. Many of the platforms actually run at 24MHz timer frequency (Eg. EVMs of DM355, DM365 and OMAP-L1). The comment also serves as a porting alert. Signed-off-by: Sekhar Nori <nsekhar@ti.com> Signed-off-by: Kevin Hilman <khilman@deeprootsystems.com>

2010-02-04davinci: cpuidle: move mapping of DDR2 controller registers out of driverSekhar Nori

2010-02-04davinci: make it possible to include clock.h and psc.h in assembly codeSekhar Nori
psc.h contains register defines for PSC module which need to be accessed in assembly code which helps the DA850/OMAP-L138 SoC go to sleep. Shutting down DDR clock using PSC is a part of the sleep procedure. Also, the PLL related hardware definitions in clock.h are needed in assembly code to bypass the DDR2 PLL.

2010-02-04davinci: move PSC register definitions from psc.c to psc.hSekhar Nori
The motivation behind the change is to use the same definitions in the assembly code responsible for suspending the SoC, a part of which is to clock gate the DDR2 clock. Note that the assembly code cannot invoke the C function meant for this. The main reason being that stack in DDR2 cannot be accessed while DDR2 clock is being clock gated.

regulator Using a device_initcall() for initializing the voltage regulator on DA850 is not such a good idea because it gets called for all platforms - even those who do not have a regulator implemented. This leads to a big fat warning message during boot-up when regulator cannot be found. Instead, tie initialization of voltage regulator to cpufreq init. Define a platform specific init call which in case of DA850 gets used for initializing the regulator. On other future platforms it can be used for other purposes.

2009-11-25DaVinci: rename setup_usb() to davinci_setup_usb()Sergei Shtylyov
Rename setup_usb() into davinci_setup_usb(). While at it: - move its declaration from <mach/common.h> to more fitting <mach/usb.h>; - teach it to handle values of the 'mA' parameter greater than 510 and thus pass 1000 instead of 500 for the power switches capable of sourcing over 1 A; - teach it to handle odd values of the 'potpgt_ms' parameter...

2009-11-25DaVinci: remove unneeded #include'sSergei Shtylyov
There have accumulated quite a lot of them after the code reorganizations... In several cases I had to replace #include <linux/dma-mapping.h> which wasn't needed directly but happened to #include <linux/err.h> which was needed.

2009-11-25davinci: RMII support for DA850/OMAP-L138 EVMChaithrika U S
DA850/OMAP-L138 EVM has a RMII Ethernet PHY on the UI daughter card. The PHY is enabled by proper programming of the IO Expander (TCA6416) ports. Also for RMII PHY to work, the MDIO clock of MII PHY has to be disabled since both the PHYs have the same address. This is done via the GPIO2[6] pin. This patch adds support for RMII PHY. This patch also adds a menuconfig option to select one or no peripheral connected to expander. Currently, sub-options in this menu are RMII and no peripheral.This menuconfig option is similar to the one present for UI card on DA830/OMAP-L137 EVM.

2009-11-25davinci: DA850/OMAP-L138: add frequency scaling supportSekhar Nori
Adds basic frequency scaling support for DA850/OMAP-L138. Currently, frequency scaling only on PLL0 is supported. No scaling of PLL1 as yet. Peripherals like MMC/SD which have a clock input synchronous with ARM clock will not work well since the clock will change behind their backs. Support for notification to such devices to adjust themselves to the new frequency will be added in later patches. Current defconfigs keep CPUFreq disabled so it will not affect normal operation. The OPP defintions assume clock input of 24MHz to the SoC. This is inline with hardcoding of input frequency in the <soc>.c files. At some point this will need to move into board dependent code as new boards appear with a different reference clock. Tested on OMAP-L138 EVM with ondemand governer and a shell script to vary processor load. Signed-off-by: Sekhar Nori <nsekhar@ti.com> Signed-off-by: Kevin Hilman <khilman@deeprootsystems.com>

Add the function to register the OHCI platform device, given the root hub related platform data passed from the board specific code. The platfrom data provide for overriding the OHCI port power and over-current bits at the board level.
