[PATCH 4/7] ARM: dts: imx6ul-txul: use panel-simple driver for LCD

From: Lothar WaÃmann
Date: Fri Oct 13 2017 - 06:44:06 EST

Convert the TXUL board support to use the panel-simple driver.
The now obsolete 'display-timings' node is kept for compatibility with
U-Boot, which derives its display configuration therefrom.
