Subject: [PATCH 4/5] arm64: dts: imx8mn: Move usdhc clocks assignment to board DT
Date:   Wed, 16 Oct 2019 10:14:26 +0800
Message-Id: <1571192067-19600-4-git-send-email-Anson.Huang@nxp.com>
In-Reply-To: <1571192067-19600-1-git-send-email-Anson.Huang@nxp.com>
References: <1571192067-19600-1-git-send-email-Anson.Huang@nxp.com>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

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.
