From 13132b3f44d3600983aceb7e9920b8ebb55a7cf8 Mon Sep 17 00:00:00 2001 From: Geert Uytterhoeven Date: Thu, 1 Jun 2017 12:27:00 +0200 Subject: [PATCH] ARM: dts: armadillo800eva: Split LCD mux and gpio Configuration of the lcd0 pinmux group and GPIO hog for the external GPIO mux are done using a single device node, causing the "output-high" property to be applied to both. This will fail for the pinmux group, but doesn't cause any harm, as the failure is ignored silently. However, after "pinctrl: sh-pfc: propagate errors on group config", the failure will become fatal, leading to a broken display: sh-pfc e6050000.pin-controller: pin_config_group_set op failed for group 102 sh-pfc e6050000.pin-controller: Error applying setting, reverse things back sh-pfc e6050000.pin-controller: failed to select default state Move the GPIO hog to its own node to fix this.
