[PATCH 2/5] arm64: dts: imx8mq: Move usdhc clocks assignment to board DT
From: Anson Huang
Date: Tue Oct 15 2019 - 22:17:37 EST
usdhc's clock rate is different according to different devices
connected, so clock rate assignment should be placed in board
DT according to different devices connected on each usdhc port.
