From 1f45e8c6d0161f044d679f242fe7514e2625af4a Mon Sep 17 00:00:00 2001 From: Heiko Stuebner Date: Sun, 29 Nov 2015 19:46:09 +0100 Subject: ARM: dts: rockchip: add startup delay to rk3288-veyron panel-regulators 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.
