Allwinner H3 SPI controller has same architecture as A31. So most configuration is identical except one thing - FIFO capacity.
A31 H3 ------------------------------------ Number of controllers 4 2 Number of FIFO depth 128 64 Transfer bits 8 8
Register maps are sharable, so sun6i SPI driver is reusable with device configuration.
Tested on Nano Pi M1 and SPI slave device is TI LP8860.
