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
