xilinx_spi: add support for the DS570 IP.

2009-12-09T01:48:14Z

This patch adds in support for the DS570 IP. It's register compatible with the DS464, but adds support for 8/16/32 SPI. The 8/16/32 support is added by attaching callbacks reading/writing the proper amount of data. To indicate to the driver which amount of bits to use a new field is introduced in the platform data struct.

xilinx_spi: Switch to iomem functions and support little endian.

2009-12-09T01:48:14Z

This patch changes the out_(be)(8|16|32) and in_(be)(8|16|32) calls to 32 bits ioread/iowrite. The read and write function are attached to the internal struct as callbacks, callback is selected depending on endianess. This will also build on platforms not supporting the in/out calls for instance x86. Acked-by: Grant Likely Tested-by: John Linn Signed-off-by: Richard Röjfors Signed-off-by: Grant Likely

xilinx_spi: Split into of driver and generic part.

2009-12-09T01:48:14Z

This patch splits the xilinx_spi driver into a generic part and a OF driver part. The reason for this is to later add in a platform driver as well. Tested-by: John Linn Signed-off-by: Richard Röjfors Signed-off-by: Grant Likely
