From 73c89ead71859af7f439ac983e9e6f610448d44e Mon Sep 17 00:00:00 2001 From: Sean Paul Date: Mon, 13 Aug 2018 17:30:43 -0400 Subject: [PATCH] drm/bridge: ti-sn65dsi86: Move panel_prepare() to pre_enable() prepare() is the old-timey way to say pre_enable(). It should be called before modeset. This fixes an issue where the panel on cheza must have the regulator always-on/boot-on for it to work.
