This is an interesting patch for me because it seems I have to deal with
drive-strength soon, as well, for the SDHI driver. You basically fall
back here to simply read the drive strength value from ACPI, right? So,
do you think it makes sense then to have a similar encoded value from DT
(maybe "mmc-fixed-driver-type-<n>" with n=0..4)? This is a largely
reduced encoding of what you proposed in 2015 [1] but may be more
pragmatic for soldered on-board devices working on their max speeds with
fixed voltages and frequencies? Or did I get something wrong?

Thanks,
