Well, maybe we still should do that, if we split the resets too at least
apb[12] would line up again.
I don't know what to do with these bus things any more, all variants I
sent had issues somewhere...

The datasheet mentions SDC0_DET function on PF6, so I thought this is
sort of fixed to this pin now. All designs I've seen use this pin.

AFAIK, Arnd had some objections, but he never got back to us when we
explained how the hardware was laid out, so I don't know if they still
apply.

Why is it set as a gpio then if it is a separate function?

Hmm, not in my version, I've "Allwinner_H3_Datasheet_V1.0.pdf" and there
PF6 only has generic input / output functionality.

I guess because we do not support this in the mmc driver yet. Also on
older devices the mmc controller has build-in card-detection features
(using the data lines in that case) but we've never supported this since
none of the boards sofar have been using it.
For now we can just treat PF6 as a gpio, until someone figures out how
to do this inside the mmc driver.

Hm, indeed, it isn't mentioned in the Port Controller documentation, but
the table on page 76 (3.2. GPIO Multiplexing Functions) has it.

I could not find any documentation or reference how to use it, probably

v1.1 has an "SDC0_DET" function for PF6 in the GPIO mux functions table.

I've requested the datasheet be publicly released with MMC and PRCM
sections included:
