Subject: [PATCH 5/5] arm64: allwinner: dts: a64: add LCD-related device nodes for PinePhone
Date:   Thu, 12 Mar 2020 00:33:29 +0800
Message-Id: <20200311163329.221840-6-icenowy@aosc.io>
In-Reply-To: <20200311163329.221840-1-icenowy@aosc.io>

Precedence: bulk

PinePhone uses PWM backlight and a XBD599 LCD panel over DSI for
display.

Add its device nodes.
