Subject: [PATCH 3/4] arm64: dts: ls1028a: fix FlexSPI clock
Date: Sun,  1 Nov 2020 20:20:52 +0100	[thread overview]
Message-ID: <20201101192053.18644-3-michael@walle.cc> (raw)
In-Reply-To: <20201101192053.18644-1-michael@walle.cc>

Now that we have a proper driver for the FlexSPI interface use it. This
will fix SCK frequency switching on Layerscape SoCs.

This was tested on the Kontron sl28 board.
