From 3c29ba8e7c78dee1a8a59cadf235d6b93489a3b4 Mon Sep 17 00:00:00 2001 From: Douglas Anderson Date: Thu, 20 Jun 2019 11:20:56 -0700 Subject: Revert "ARM: dts: rockchip: add startup delay to rk3288-veyron panel-regulators" This reverts commit 1f45e8c6d0161f044d679f242fe7514e2625af4a. This 100 ms mystery delay is not on downstream kernels and no longer seems needed on upstream kernels either [1]. Presumably something in the meantime has made things better. A few possibilities for patches that have landed in the meantime that could have made this better are commit 3157694d8c7f ("pwm-backlight: Add support for PWM delays proprieties."), commit 5fb5caee92ba ("pwm-backlight: Enable/disable the PWM before/after LCD enable toggle."), and commit 6d5922dd0d60 ("ARM: dts: rockchip: set PWM delay backlight settings for Veyron") Let's revert and get our 100 ms back.
