[PATCH v7 0/3] Add support Rockchip Soc LVDS

[PATCH v7 0/3] Add support Rockchip Soc LVDS

[Sandy Huang]

this patches add support Rockchip RK3288 LVDS support, based on patches from
Mark yao[0] and Heiko Stuebner[1].

[0]: https://github.com/RockchipOpensourceCommunity/popmetal-kernel-3.14
[1]: http://lists.infradead.org/pipermail/linux-rockchip/2015-April/002830.html

Changes:
- Update rockchip_lvds_encoder_helper_funcs to atomic API
- Add bridge function for RGB/LVDS convert to other output type
- Fix some unreasonable define
- Adapter to the latest rockchip DRM driver framework
- Add pinctrl for RGB output type
- Reseved some define for rockchip next Soc

+Rockchip RK3288 LVDS interface
+================================
+
+Required properties:
+- compatible: matching the soc type, one of
+	- "rockchip,rk3288-lvds";
+
+- reg: physical base address of the controller and length
+	of memory mapped region.
+- clocks: must include clock specifiers corresponding to entries in the
+	clock-names property.
+- clock-names: must contain "pclk_lvds"
+
+- avdd1v0-supply: regulator phandle for 1.0V analog power
+- avdd1v8-supply: regulator phandle for 1.8V analog power
+- avdd3v3-supply: regulator phandle for 3.3V analog power
+
+- rockchip,grf: phandle to the general register files syscon
+- rockchip,output: "rgb", "lvds" or "duallvds", This describes the output interface
+
+Optional properties:
+- pinctrl-names: must contain a "lcdc" entry.
+- pinctrl-0: pin control group to be used for this controller.
+
+Required nodes:
+
+The lvds has two video ports as described by
+	Documentation/devicetree/bindings/media/video-interfaces.txt
+Their connections are modeled using the OF graph bindings specified in

+
+- video port 0 for the VOP input, the remote endpoint maybe vopb or vopl
+- video port 1 for either a panel or subsequent encoder

of the patches :-)
