> According to a subsequent revert in the vendor kernel, the original
> change was based on unclear documentation and was in fact incorrect.

> Emprically, my board's SD card at 50MHz and eMMC at 200MHZ seem to get
> lucky with a phase where it had no impact, but limiting the eMMC clock
> to 150MHz to match the nominal limit for the I/O pins made it virtually
> unusable, constantly throwing errors and retuning. With this revert, it
> starts behaving perfectly at 150MHz too.
