spi: Add Freescale/Motorola Coldfire QSPI driver

2010-01-20T20:49:44Z

Add support for the QSPI controller found some on Freescale/Motorola Coldfire MCUs. Full duplex, active high cs, spi modes 0-3 and word sizes 8-16 bits are supported. The hardware drives the MISO, MOSI and SCLK lines, but the chip selects are managed via GPIO and must be configured by the board code. The QSPI controller has an 80 byte buffer which allows us to transfer up to 16 words at a time. For transfers longer than 16 words, we split the buffer in half so we can update in one half while the controller is operating on the other half. Interrupt latencies then ultimately limits our sustained thru-put to something less than half the maximum speed supported by the part. Signed-off-by: Steven King Signed-off-by: Grant Likely

spi: Add s3c64xx SPI Controller driver

2009-12-17T15:58:17Z

Each SPI controller has exactly one CS line and as such doesn't provide for multi-cs. We implement a workaround to support multi-cs by _not_ configuring the mux'ed CS pin for each SPI controller. The CS mechanism is assumed to be fully machine specific - the driver doesn't even assume some GPIO pin is used to control the CS. The driver selects between DMA and POLLING mode depending upon the xfer size - DMA mode for xfers bigger than FIFO size, POLLING mode otherwise. The driver has been designed to be capable of running SoCs since s3c64xx and till date, for that reason some of the register fields have been passed via, SoC specific, platform data.

spi_s3c24xx: add FIQ pseudo-DMA support

2009-12-17T15:57:01Z

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.

Add OMAP spi100k driver

2009-12-13T08:02:11Z

This change adds the OMAP SPI 100k driver created by Fabrice Crohas . This SPI bus is found on OMAP7xx-series smartphones, and for many, the touchscreen is attached to this bus. The lion's share of the work was done by Fabrice on this driver -- I am merely porting it from the Linwizard project on his behalf. Signed-off-by: Cory Maccarrone Signed-off-by: Grant Likely
