Does this work with boards where we don't have any MMC supplies? Or are we just deferring the probe indefinitely there?

For boards that power MMC unconditionally, are we supposed to add dummy regulators to make them work with this patchset?
I believe that dummy (fixed) regulators are supposed to be provided in all cases where the platform doesn't actually have one. The fact that everything worked OK without them before this patch was most likely a mistake/accident.
That's the general idea; clearly there *are* supplies here, they're just not software controlled supplies. -------------- next part -------------- A non-text attachment was scrubbed...
