Okay, just to be clear on the way forward. I spoked with Mark Brown
offlist, and he will/has picked up the regulator patch and will send
it as fix for the 4.3 rc[n].

Regarding the ARM patch here, I guess Tony might as well handle it and
send through arm-soc, especially since the regression won't be fixed
within my mmc tree anyway.

So, I am going to leave my next branch as is - and thus relying on
that the regression for OMAP will be fixed in some the 4.3 rc[n].

Kind regards
Uffe
