This patch series integrates Renesas RSPI on the RZ/A1H aka R7S72100 SoC,
and the Genmai development board.
The series is based on renesas-devel-v3.13-rc5-20131226, with Magnus'
pinctrl, Wolfram's riic, and Simon's sh_eth work applied on top.
It was tested on the Genmai development board (genmai-reference), using
an in-kernel version of Documentation/spi/spidev_test.c, exercising
loopback mode on rspi1, with the same outcome as the SDK reference code.
Notes:
1. The proposed DT bindings also talk about QSPI on the R8A779x, as those
SoCs use the same driver.
2. As the actual spi-rspi driver doesn't use DT yet, platform devices and
spi board info are still used from C to instantiate SPI buses and their
children, while pinctrl is performed by DT.
3. It will not work with the non-reference version of genmai, due to
missing pinmux configuration in setup-r7s72100.c.
4. Patches [4/8] and [5/8] are new.
