Subject: [PATCH] arm64: dts: ls1028a: add missing SPI nodes
Date: Thu, 13 Feb 2020 19:56:06 +0100 [thread overview]
Message-ID: <20200213185606.2747-1-michael@walle.cc> (raw)
The LS1028A has three (dual) SPI controller. These are compatible with
the ones from the LS1021A. Add the nodes.
This was tested on a custom board.
