Subject: [PATCH v2 06/12] backlight: Document consumers of backlight nodes
Date: Wed, 1 Jul 2015 11:41:01 +0200 [thread overview]
Message-ID: <1435743667-11987-7-git-send-email-tomeu.vizoso@collabora.com> (raw)
In-Reply-To: <1435743667-11987-1-git-send-email-tomeu.vizoso@collabora.com>
Add a small note that makes explicit that properties named 'backlight'
contain phandles to backlight nodes.
This is needed so that we can automatically extract dependencies on
backlight devices by assuming that a property with that name contains a
phandle to such a device.
Signed-off-by: Tomeu Vizoso <tomeu.vizoso@collabora.com>
---
Changes in v2:
- Document that consumers of backlight devices can use the 'backlight'
property to hold a phandle to the backlight device.

+Backlight user nodes
+--------------------
+
+Nodes such as display panels that refer to backlight devices can do so by simply having a property named 'backlight' that contains a phandle to a backlight node.

+Example:
+
+ backlight: backlight {
+ compatible = "gpio-backlight";
+ gpios = <&gpio3 4 GPIO_ACTIVE_HIGH>;
+ };
+
