2012-01-31ARM: S3C24XX: move spi-s3c24xx platdata out of machHeiko Stuebner1-27/+0
spi.h now only contains the definition of the platform data structure for the driver in spi-s3c24xx.c . Therefore it does not need to stay in include/mach but can instead live in linux/spi/s3c24xx.h .

2012-01-27ARM: S3C24XX: remove unused spi gpio setup functionsHeiko Stuebner1-11/+0
A grep through the kernel source revealed that neither the config-options nor the defined functions are used anywhere in the kernel. There was also no activity in this regard through the last kernel releases, so it seems this situation will not change in the future. Therefore this patch removes this seemingly dead code.

2009-12-17spi_s3c24xx: add FIQ pseudo-DMA supportBen Dooks1-0/+2
Add pseudo-DMA by FIQ to the S3C24XX SPI driver. This allows the driver to get DMA-like performance where there are either no free DMA channels or when doing transfers that required both TX and RX data paths. Since this patch requires the addition of an assembly file to hold the FIQ code, we rename the module (instead of adding a rename of the .c file to this patch). We expect most users are loading this via udev and thus there should be no change to the userland configuration.

2009-08-14ARM: S3C24XX: Add SPI bus 1 on GPD8 through GPD10Ben Dooks1-0/+3

2009-01-07spi: use generic gpio calls in spi_s3c24xx_gpioBen Dooks1-1/+1
Change the spi_s3c2410 driver to use the generic gpio calls that are now available.

2008-12-16[ARM] S3C24XX: Default SPI pin configuration for SPIBen Dooks1-0/+7
Add a set of default pin configuration routines for setting up the SPI gpio configuration when using the hardware SPI driver. Signed-off-by: Ben Dooks <ben-linux@fluff.org>
2008-10-16spi_s3c24xx: pin configuration updatesBen Dooks1-0/+1
Add a pin configuration callback for the s3c24xx SPI driver, as there are several options depending on the channel and the chip in use. This is needed as the controller may not have been setup by the initial bootloader and the fact that the SPI controller gets reset over suspend/resume into slave mode but the GPIO function registers do not.
