These two patches together fix a boot speed regression on sc7180-trogdor boards which use off-on-delay-us together with regulator-boot-on with the eDP power rail.
The first patch is _almost_ a revert of another patch. Depending on when the regulator is probed and the actual delay, the end result might be the same as a revert or might result in a delay that's somewhere between "no delay" and a full delay. As talked about in the patch, I believe this is the correct behavior and, if the problems fixed in the original patch are still present, I'm hoping that they can be fixed in a cleaner way.
The first patch doesn't fully eliminate the boot speed regression, it only gets us back ~250 of the 500 ms delay. The second patch gets us the rest of the way.
The two patches can be applied independently of each other.
Douglas Anderson (2): regulator: core: Shorten off-on-delay-us for always-on/boot-on by time since booted regulator: fixed: Set PROBE_PREFER_ASYNCHRONOUS
