Subject: [PATCH 2/2] ARM: dts: rockchip: add input supplies for the act8846 on Radxa Rock
Date: Sat, 07 Mar 2015 15:30:06 +0100 [thread overview]
Message-ID: <1971287.rRrUEZJPze@phil> (raw)
In-Reply-To: <1709506.shJhJsMxOa@phil>
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@sntech.de>

I'll apply this one to my dts branch myself, if patch 1/2 is accepted
