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
