[PATCH 0/4] Add Allwinner A31 SPI controller support

From: Maxime Ripard

Hi everyone,

This patchset brings support for the SPI controller found in the
Allwinner A31 SoC.

Even though the controller supports DMA, the driver only supports PIO
mode for now. This driver will be used to bring up and test DMA on the
SoC, so support for the DMA will come eventually.

It doesn't support transfer larger than the FIFO size (128 bytes) for
now, so this is kind of a blocker against inclusion, but I expect it
to be fixed by v2.


Maxime Ripard (4):
clk: sunxi: Add support for PLL6 on the A31
ARM: sun6i: dt: Add PLL6 and SPI module clocks
spi: sunxi: Add Allwinner A31 SPI controller driver
ARM: sun6i: dt: Add SPI controllers to the A31 DTSI
