Subject: [PATCH v1 3/5] ARM: dts: rockchip: add eDP/panel display device nodes for rk3288-evb
Date: Tue, 28 Jun 2016 12:51:18 +0800	[thread overview]
Message-ID: <1467089478-18670-1-git-send-email-ykk@rock-chips.com> (raw)
In-Reply-To: <1467089288-18355-1-git-send-email-ykk@rock-chips.com>

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.
