Subject: [PATCH] ARM: dts: iwg20d-q7-common: Fix touch controller probe failure
Date: Fri, 7 Aug 2020 16:20:38 +0100 [thread overview]
Message-ID: <20200807152039.10961-1-biju.das.jz@bp.renesas.com> (raw)
Remove powerdown-gpios property from lvds-receiver node as it results in
touch controller driver probe failure.
As per the iWave RZ/G1M schematic, the signal LVDS_PPEN controls supply
voltage for touch panel, LVDS receiver and RGB LCD panel.
Fixes: 6f89dd9e9325 ("ARM: dts: iwg20d-q7-common: Add LCD support")
