Subject: [PATCH] arm64: dts: imx8mm: Change SDMA1 ahb clock for imx8mm
Date: Mon, 16 Dec 2019 05:15:30 -0600 [thread overview]
Message-ID: <20191216111530.29558-1-aford173@gmail.com> (raw)
Using SDMA1 with UART1 is causing a "Timeout waiting for CH0" error.
This patch changes to ahb clock from SDMA1_ROOT to AHB which
fixes the timeout error.
Fixes: a05ea40eb384 ("arm64: dts: imx: Add i.mx8mm dtsi support")
Signed-off-by: Adam Ford <aford173@gmail.com>

A similar fix was made to the i.MX8MQ for the same reason
