Subject: ARM: dts: rockchip: add input supplies for the act8846 on Radxa Rock
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=776920e16a74b0009765d84b6c267fe820966307;p=linux-beck.git

ARM: dts: rockchip: add input supplies for the act8846 on Radxa Rock

On the Radxa Rock board most supplies come from the static 5v vsys supply, but
the inl1-supply comes from the REG4 of the act8846 itself. Model this dependency
using the added supply-handling to make sure the supplying regulator gets handled
correctly and not accidentially turned off.
