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. Thanks!
