From d4da51213a2ce337cb98a468886d5b0bc1e45bcc Mon Sep 17 00:00:00 2001 From: Yakir Yang Date: Tue, 28 Jun 2016 12:51:18 +0800 Subject: ARM: dts: rockchip: add eDP/panel display device nodes for rk3288-evb The default eDP panel on RK3288 EVB board is LG LP079QX1-SP0V TFT LCD, we haven't declared the panel regulator in the 'panel-simple' device node here, so the specific board like ACT8846 / RK8080 need to support the panel power supply.
