    Subject[PATCH AUTOSEL 5.4 015/107] arm64: dts: imx8mm: Change SDMA1 ahb clock for imx8mm
    Date
    From: Adam Ford <aford173@gmail.com>

    [ Upstream commit 24a572bf67994223e722cadfe663e15ba221882a ]

    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")
