This patch adds spi->mode support for the AMBA pl022 driver and allows spidev to correctly alter SPI modes. Unused fields used in the pl022 header file for the pl022_config_chip have been removed. The ab8500 client driver selects the data transfer size instead of the platform data.

2010-07-11powerpc/cpm: Reintroduce global spi_pram struct (fixes build issue)Anton Vorontsov
spi_t was removed in commit 644b2a680ccc51a9ec4d6beb12e9d47d2dee98e2 ("powerpc/cpm: Remove SPI defines and spi structs"), the commit assumed that spi_t isn't used anywhere outside of the spi_mpc8xxx driver. But it appears that the struct is needed for micropatch code. So, let's reintroduce the struct. Fixes the following build issue: CC arch/powerpc/sysdev/micropatch.o micropatch.c: In function 'cpm_load_patch': micropatch.c:629: error: expected '=', ',', ';', 'asm' or '__attribute__' before '*' token micropatch.c:629: error: 'spp' undeclared (first use in this function) micropatch.c:629: error: (Each undeclared identifier is reported only once micropatch.c:629: error: for each function it appears in.)

2010-05-25spi: move bitbang txrx utility functions to private headerhartleys
A number of files in drivers/spi fail checkincludes.pl due to the double include of <linux/spi/spi_bitbang.h>. The first include is needed to get the struct spi_bitbang definition and the spi_bitbang_* function prototypes. The second include happens after defining EXPAND_BITBANG_TXRX to get the inlined bitbang_txrx_* utility functions. The <linux/spi/spi_bitbang.h> header is also included by a number of other spi drivers, as well as some arch/ code, in order to use struct spi_bitbang and the associated functions. To fix the double include, and remove any potential confusion about it, move the inlined bitbang_txrx_* functions to a new private header in drivers/spi and also remove the need to define EXPAND_BITBANG_TXRX.

2010-05-25spi/omap2_mcspi: add turbo mode supportRoman Tereshonkov
Turbo mode allows to read data to shift register when rx-buffer is full thus improving the perfomance. This feature is available for RX-only mode. In PIO turbo mode when the penultimate word is available in RX-buffer the controller should be disabled before reading data to prevent the next transaction triggering. The controller itself handles the last word to be correctly loaded to shift-register and then transferred to RX-buffer. The turbo mode is enabled by setting turbo_mode parameter to 1. This parameter is a part of omap2_mcspi_device_config structure which is passed through the spi_device controller_data pointer.

This patch is a removes the extra copies from struct of_platform_driver and converts all users to the device_driver members. This patch is a pretty mechanical change. The usage model doesn't change and if any drivers have been missed, or if anything has been fixed up incorrectly, then it will fail with a compile time error, and the fixup will be trivial. This patch looks big and scary because it touches so many files, but it should be pretty safe.
