Can this go above the pinctrl zone in this file? Preferably sorted
alphabetically by phandle.
Sure, looks like I just added
it based on sort order. Didn't
notice that it fell below the
pinctrl zone.

Any reason to not combine this stuff with the previous patch?
I split it into two separate
patches just to show that sc7280
supports two ways of bringing
modem out of reset and method
used is determined by the platform.
