2008-04-28gxfb: use PCI_DEVICE() for gxfb's pci device tableAndres Salomon

2008-04-28gxfb: don't enable the CRT DACs when we are in flatpanel modeJordan Crouse

2008-04-28gxfb: set the right registers to tweak the sync polarityJordan Crouse
While running in flatpanel mode it is important to change the FP sync bits (VG register 0x408) rather then the CRT sync bits (VG register 0x008). This patch keeps the CRT sync bits at default when a flatpanel exists. Note that this also fixes inverted logic; we want CRT_VSYNC_POL to be set (ie, vsync is normally high) when FB_SYNC_VERT_HIGH_ACT is unset.

2008-04-28x86: geode: MSR cleanupAndres Salomon
This cleans up a few MSR-using drivers in the following manner: - Ensures MSRs are all defined in asm/geode.h, rather than in misc places - Makes the naming consistent; cs553[56] ones begin with MSR_, GX-specific ones start with MSR_GX_, and LX-specific ones start with MSR_LX_. Also, make the names match the data sheet. - Use MSR names rather than numbers in source code - Document the fact that the LX's MSR_PADSEL has the wrong value in the data sheet. That's, uh, good to note.

Add support for the framebuffers with non-native endianness. This is done via FBINFO_FOREIGN_ENDIAN flag that will be used by the drivers.

2008-04-28fbdev: make the best-fit section of fb_find_mode return the closest matching ↵Michal Januszewski
mode Currently, if a perfect match in terms of resolution is not found, fb_find_mode() only looks for a best-fit mode among modes with a higher resolution than the one requested. Thus, if the user requests a resolution higher than the largest supported one, they are dropped to the default mode (usually a low resolution one). Change this behaviour so that all valid video modes are considered when looking for a best-fit mode, while still preferring modes with a higher resolution.

That is, this marks gpio numbers which will be claimed by drivers that haven't yet been loaded, and thus are not available for dynamic gpio number allocation.

2008-04-28gpiolib: dynamic gpio number allocationAnton Vorontsov
If gpio_chip->base is negative during registration, gpiolib performs dynamic base allocation. This is useful for devices that aren't always present, such as GPIOs on hotplugged devices rather than mainboards. (This behavior was previously specified but not implemented.) To avoid using any numbers that may have been explicitly assigned but not yet registered, this dynamic allocation assigns GPIO numbers from the biggest number on down, instead of from the smallest on up.

2008-04-28gpiolib: better rmmod infrastructureGuennadi Liakhovetski
As long as one or more GPIOs on a gpio chip are used its driver should not be unloaded. The existing mechanism (gpiochip_remove failure) doesn't address that, since rmmod can no longer be made to fail by having the cleanup code report errors. Module usecounts are the solution. Assuming standard "initialize struct to zero" policies, this change won't affect SOC platform drivers. However, drivers for external chips (on I2C and SPI busses) should be updated if they can be built as modules.

Updates to the i.MX SPI controller driver: 1) Some comments changed and/or added. 2) End of transfers is now managed on TXFIFO empty interrupt after the last write to TXFIFO. This speeds interrupt execution by removing the wait for TXFIFO to become empty. On TXFIFO empty interrupt the handler needs only to poll for the end of the ongoing transaction (SPI_CONTROL_XCH) to close the transfer. (2.1) Write only transfers are closed flushing RXFIFO. (2.2) Read transfers are closed reading trailing bytes from RXFIFO. (2.3) Read transfers where RXFIFO overrun occurred are closed by flushing RXFIFO and aborting the message. 3) Fifos are now flushed via SPI disable after the end of ongoing transaction.

2008-04-28serial 8250: tighten test for using backup timerAlex Williamson
Thomas Koeller had reported an issue where a device that had been making use of the UART_BUG_TXEN code in the 8250 driver was mistakenly being caught by the backup timer test, causing the device to work improperly. To fix this, tighten the test requirements to enable the backup timer workaround. The backup timer is really meant to catch UARTs that don't re-assert the THRE interrupt. The expectation is that they do initially assert THRE. This patch clarifies the test.

Russell King noticed this one: We have to avoid replacing B0 when we pick a baud rate for a "hung up" port.

2008-04-28Fix tty speed handling on 8250Alan Cox
We try and write the correct speed back but the serial midlayer already mangles the speed on us and that means if we request B0 we report back B9600 when we should not. For now we'll hack around this in the drivers and serial code, pending a better long term solution.

2008-04-28return pfn from direct_access, for XIPJared Hulbert
Alter the block device ->direct_access() API to work with the new get_xip_mem() API (that requires both kaddr and pfn are returned). Some architectures will not do the right thing in their virt_to_page() for use by XIP (to translate from the kernel virtual address returned by direct_access(), to a user mappable pfn in XIP's page fault handler. However, we can't switch it to just return the pfn and not the kaddr, because we have no good way to get a kva from a pfn, and XIP requires the kva for its read(2) and write(2) handlers. So we have to return both.
