Subject: [PATCH 5/5] arm64: allwinner: dts: a64: add LCD-related device nodes for PinePhone
Date: Thu, 12 Mar 2020 00:33:29 +0800 [thread overview]
Message-ID: <20200311163329.221840-6-icenowy@aosc.io> (raw)
In-Reply-To: <20200311163329.221840-1-icenowy@aosc.io>
PinePhone uses PWM backlight and a XBD599 LCD panel over DSI for
display.
Add its device nodes.
