Hello,
This series implements SPI master driver for Cirrus Logic EP93xx SPI
controllers.
This is fifth iteration of the driver.
Changes to the previous version:
- addressed review comments
- added priming the TX FIFO when transfer is started
- in case of ROR interrupt we clear it
- added documentation in Documentation/spi/ep93xx_spi which provides
sample code how the driver can be hooked into platform data
I tested this on TS-7260 board with at25 and mmc_spi drivers. Now that I have
Sim.One board, which is EP9307 based, I also tested with that (I hacked the
board a bit to get EGPIO9 as a chip select).
Note that patch 2/2 depends on patch that is already in Russell's patch
tracking system:

Thanks,
MW
