[PATCH 0/3] Support H3 SPI controller

[Milo Kim <woogyom.kim@xxxxxxxxx>]

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.
