[PATCH 0/7] Add Allwinner A10 SPI Controller Driver

Hi,

This patchset brings support for the SPI controller found in the
Allwinner A10 and derived SoCs.

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 (64 bytes) for
now, It's one of the things that will be fixed whenever we will have
DMA support.

Thanks!
Maxime
