xilinx_spi: add support for the DS570 IP. 2009-12-09T01:48:14+00:00 Richard Röjfors richard.rojfors@mocean-labs.com 2009-11-13T11:28:55+00:00 c9da2e125588677d74324df5088149063d578e8f 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.

proper amount of data. To indicate to the driver which amount of bits

xilinx_spi: Switch to iomem functions and support little endian. 2009-12-09T01:48:14+00:00 Richard Röjfors richard.rojfors@mocean-labs.com 2009-11-13T11:28:49+00:00 86fc593599c11b62a11c85b4d7b709089df15c29 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.

The reason for this is to later add in a platform driver as well.
