Subject: [PATCH v11 08/19] dt-bindings: add document for rockchip variant of analogix_dp
Date: Wed, 16 Dec 2015 11:38:48 +0800 [thread overview]
Message-ID: <1450237128-2131-1-git-send-email-ykk@rock-chips.com> (raw)
In-Reply-To: <1450236018-1118-1-git-send-email-ykk@rock-chips.com>
Rockchip DP driver is a helper driver of analogix_dp coder driver,
so most of the DT property should be descriped in analogix_dp document.

+Rockchip RK3288 specific extensions to the Analogix Display Port
+================================
+
+Required properties:
+- compatible: "rockchip,rk3288-edp";
+
+- reg: physical base address of the controller and length
+
+- clocks: from common clock binding: handle to dp clock.
+ of memory mapped region.
+
+- clock-names: from common clock binding:
+ Required elements: "dp" "pclk"
+
+- resets: Must contain an entry for each entry in reset-names.
+ See ../reset/reset.txt for details.
+
+- pinctrl-names: Names corresponding to the chip hotplug pinctrl states.
+- pinctrl-0: pin-control mode. should be <&edp_hpd>
+
+- reset-names: Must include the name "dp"
+
+- rockchip,grf: this soc should set GRF regs, so need get grf here.
+
+- ports: there are 2 port nodes with endpoint definitions as defined in
+ Documentation/devicetree/bindings/media/video-interfaces.txt.
+ Port 0: contained 2 endpoints, connecting to the output of vop.
+ Port 1: contained 1 endpoint, connecting to the input of panel.
+
+For the below properties, please refer to Analogix DP binding document:
+ * Documentation/devicetree/bindings/drm/bridge/analogix_dp.txt
+- phys (required)
+- phy-names (required)
+- hpd-gpios (optional)
