[v3,06/12] panel/s6e8aa0: add DT bindings

Commit Message

Andrzej Hajda March 28, 2014, 11:52 a.m. UTC

The patch adds bindings for s6e8aa0 panel.
Bindings describes panel resources, boot delays,
display timings, orientation and physical size.

v2
- removed samsung prefix from panel physical size props,
- renamed file to follow convention of panel bindings

v3
- reset-gpio renamed to reset-gpios
- added video interfaces bindings

+Samsung S6E8AA0 AMOLED LCD 5.3 inch panel
+
+Required properties:
+  - compatible: "samsung,s6e8aa0"
+  - reg: the virtual channel number of a DSI peripheral
+  - vdd3-supply: core voltage supply
+  - vci-supply: voltage supply for analog circuits
+  - reset-gpios: a GPIO spec for the reset pin
+  - display-timings: timings for the connected panel as described by [1]
+
+Optional properties:
+  - power-on-delay: delay after turning regulators on [ms]
+  - reset-delay: delay after reset sequence [ms]
+  - init-delay: delay after initialization sequence [ms]
+  - panel-width-mm: physical panel width [mm]
+  - panel-height-mm: physical panel height [mm]
+  - flip-horizontal: boolean to flip image horizontally
+  - flip-vertical: boolean to flip image vertically
+
+The device node can contain one 'port' child node with one child
+'endpoint' node, according to the bindings defined in [2]. This
+node should describe panel's video bus.
