[PATCH 0/1] arch: arm: dts: imx8mm-cl-iot-gate.dts: add no-mmc-hs400 to mmc2
From: "Ying-Chun Liu (PaulLiu)" paul.liu@linaro.org
The eMMC device on imx8mm-cl-iot-gate seems not support hs400. When booting 6.1.0 kernel we got the following error.
mmc2: mmc_select_hs400es failed, error -110 mmc2: error -110 whilst initialising MMC card
Add no-mmc-hs400 to mmc2 node solves the problem.

Looking at the usdhc2 node it passes:
no-1-8-v; mmc-ddr-1_8v;
Would that work for usdhc3 as well?
I don't have access to the schematics to confirm.
Also, this board dts has been upstreamed in kernel 6.11 (arch/arm64/boot/dts/freescale/imx8mm-iot-gateway.dts).
Please consider moving to OF_UPSTREAM at some point.
Thanks

Applied to u-boot-imx/next, thanks.
