Hello Simon,

just to clarify the changes between v1 and v2, we can't use SDR50 and

SDR104 (due to an HW issue) therefore the pinctrl for UHS has been
removed and we dropped property "sd-uhs-sdr104". High Speed has been
tested, therefore if you are happy with the patch I guess you can update the
following page accordingly:

Although (due to a bug) sdhi0 may not hold a reference to "vccq_sdhi0",

the gpio regulator will initialize "SDHI0 VccQ" at 3.3V.

I have sent another patch (mmc: tmio: check mmc_regulator_get_supply

return value) to start a discussion about a possible fix for the bug.

Let me know if you need more information.

Thanks again for following up on this.

I have applied the patch with Geert's tag.

Thanks

I have also updated the Wiki at the URL above, feel free to make any further
updates there as appropriate.

Thanks, looks okay to me.

Kind regards, Chris
