Subject: [PATCH] ARM: dts: omap3-gta04: declare backlight in lcd node
Date: Mon, 11 Feb 2019 17:20:07 +0100 [thread overview]
Message-ID: <20190211162007.15626-1-andreas@kemnade.info> (raw)
The lcd display of the gta04 has a backlight but the backlight
was not referenced in the lcd node, so screen blanking did
not turn off the backlight. Fix that.
Signed-off-by: Andreas Kemnade <andreas@kemnade.info>

the backlight property for the driver was accepted here:
