Subject: [PATCH 0/3] Support H3 SPI controller
Date: Wed, 19 Oct 2016 23:02:31 +0900 [thread overview]
Message-ID: <20161019140234.13518-1-woogyom.kim@gmail.com> (raw)
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.
