Subject: [PATCH 1/5] arm64: dts: imx8qxp: Move usdhc clocks assignment to board DT
Date: Wed, 16 Oct 2019 10:14:23 +0800 [thread overview]
Message-ID: <1571192067-19600-1-git-send-email-Anson.Huang@nxp.com> (raw)
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.
