Subject[PATCH v2] arm64: dts: sc7180: Add board regulators for MIPI camera trogdor boards
Date
Some trogdor boards have on-board regulators for the MIPI camera
components. Add nodes describing these regulators so boards with these
supplies can consume them.

Changes from v1 (https://lore.kernel.org/r/20211215003639.386460-1-swboyd@chromium.org):
* Swapped order of regulators
