Subject: [PATCH v3 8/9] arm64: dts: ls1028a: fix FlexSPI clock
Date: Sun, 8 Nov 2020 19:51:12 +0100 [thread overview]
Message-ID: <20201108185113.31377-9-michael@walle.cc> (raw)
In-Reply-To: <20201108185113.31377-1-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.
Signed-off-by: Michael Walle <michael@walle.cc>

Changes since v2:
- use device tree constants for clockgen
- also use &fspi_clk for fspi_en clock
Changes since v1:
- none
