From mboxrd@z Thu Jan 1 00:00:00 1970 From: heiko@sntech.de (Heiko Stuebner) Date: Fri, 18 Mar 2016 02:40:01 +0100 Subject: [PATCH 05/10] ARM: dts: rockchip: add core rk3288-veyron backlight and panel nodes In-Reply-To: <1458265206-15733-1-git-send-email-heiko@sntech.de> References: <1458265206-15733-1-git-send-email-heiko@sntech.de> Message-ID: <1458265206-15733-6-git-send-email-heiko@sntech.de> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org Many Veyron chromebooks share the same panel type, so define the core settings for all of them and allow the few runaways to override it later.
