ARM: dts: rockchip: add startup delay to rk3288-veyron
From: Heiko Stuebner <heiko@...> Date: Sun, 29 Nov 2015 19:46:09 +0100
Commit-Message
The panels need a bit of time to actually turn on. If this isn't observed, this results in problems when trying talk to the panels and thus produces detection errors. 100ms seem to be a safe value for the time being. Signed-off-by: Heiko Stuebner <heiko@...>
