8ea7ce9cc6 spi: sun6i: Add binding for Allwinner H3 SPI controller 
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.

3558fe900e spi: sunxi: Add Allwinner A31 SPI controller driver 
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.
