Subject: [PATCH 3/3] ARM: dts: imx6ull: change to use new compatible "fsl,imx6ull-usdhc" for usdhc
Date: Thu, 20 Dec 2018 07:49:55 +0000	[thread overview]
Message-ID: <1545292612-14471-3-git-send-email-haibo.chen@nxp.com> (raw)
In-Reply-To: <1545292612-14471-1-git-send-email-haibo.chen@nxp.com>

i.MX6ULL has errata ERR010450, there is I/O timing limitation,
for SDR mode, SD card clock can't exceed 150MHz, for DDR mode,
SD card clock can't exceed 45MHz. This patch change to use the
new compatible "fsl,imx6ull-usdhc" to follow this limitation.
