I take that the absence of a wp-gpio means that that this is a µSD slot.
Could you help me by documenting this correctly on
http://elinux.org/index.php?title=Renesas-MMC-Enabled-Speeds ?

For some reason I thought that SDHI0 wasn't exposed at all, so I guess
my reading of the documentation was incorrect.


I think you also want sd-uhs-sdr50 here too.
You can test it by removing the sd-uhs-sdr104 property.
