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.
