This supports SDHI0 on M3ULCB board SD card slot
Is SDHI3 also exposed on the M3ULCB?
No, SDHI3 is not exposed on M3ULCB.
Only SDHI0 exposed to SD slot and SDHI2 as eMMC.
If so could you consider sending patches to enable it?

I would prefer the pin nodes to be named as follows:
sdhi0_pins_3v3 -> sdhi0_pins_3v3
sdhi0_pins_1v8 -> sdhi0_pins_uhs
Likewise for SDHI2.
Okay, I will resend these changes in the next try.
Regards,
Vladimir
