[PATCH v5 0/2] spi: driver for Cirrus EP93xx SPI controller

[Mika Westerberg]

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
