2016-11-02spi: sun6i: Add binding for Allwinner H3 SPI controllerMilo Kim1-2/+23
H3 SPI has same architecture as A31 except FIFO capacity. To configure the buffer size separately, compatible property should be different. Optional DMA specifiers and example are added.

2014-02-05spi: sunxi: Add Allwinner A31 SPI controller driverMaxime Ripard1-0/+24
The Allwinner A31 has a new SPI controller IP compared to the older Allwinner SoCs. It supports DMA, but the driver only does PIO for now, and DMA will be supported eventually. Signed-off-by: Maxime Ripard <maxime.ripard@free-electrons.com> Signed-off-by: Mark Brown <broonie@linaro.org>
