Philip,
I don't think you should add yet another quirk for this. You should
plumb in a method to mask the capability registers to enable or
disable features you don't want. This would probably fix problems for
a lot of controller and board configurations.

Alan,
I have your patch in my mmc-next. Our controller indicates it SUPPORTS UHS
modes.
The regulators do NOT. Cannot switch to 1.8v.
Not the same problem as you saw.

I recently added a patch that prevents the switch to 1.8v if the host
capabilities register does not indicate support for any of the UHS
speeds (SDR50, DDR50, SDR104). This allowed our controller to work
with UHS cards in HS mode (50MHz, 3.3v).

We have h/w that does not support 1.8v signaling even though the
controller does support this. If we enable 1.8v support UHS
cards are recognised but recovery to 3.3v is not possible
depending on the SD card.
Ensure that when we do not support 1.8v UHS mode cards can
work (i
