Just FYI,
For the eMMC case, I decided not to modify sh_mmcif.c to add the OCR and

Here's a question:
The DT regulator method is good if you want to be able to control the regulator
at run-time by the system.
But for MMC and SDHI, why isn't there a way to just set the OCR voltage in the
board's DT if it's fixed (other than making a fixed regulator node)?
Why isn't there a

The SoC does not *provide* power to the card. It's not that fancy. How the 3.3v
