Subject: [PATCH 1/2] arm64: dts: imx93: assign the correct ipg/ahb clock for usdhc
Date: Wed, 3 Aug 2022 17:51:02 +0800 [thread overview]
Message-ID: <20220803095103.3883035-2-peng.fan@oss.nxp.com> (raw)
In-Reply-To: <20220803095103.3883035-1-peng.fan@oss.nxp.com>
From: Haibo Chen <haibo.chen@nxp.com>
Assign the correct ipg/ahb clock for usdhc according to CCM.
Also config IMX93_CLK_USDHC1 to 400MHz to support eMMC HS400ES mode.
Fixes: ec8b5b5058ea ("arm64: dts: freescale: Add i.MX93 dtsi support")
