ARM: dts: rockchip: add input supplies for the act8846 on Radxa Rock
From: Heiko Stuebner <heiko@...> Date: Sat, 7 Mar 2015 15:14:59 +0100
Commit-Message
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. Signed-off-by: Heiko Stuebner <heiko@...>
