+title: Common Properties for DSI Display Panels
+
+maintainers:
+  - Linus Walleij <linus.walleij@linaro.org>
+
+description: |
+  This document defines device tree properties common to DSI, Display
+  Serial Interface controllers and attached panels. It doesn't constitute
+  a device tree binding specification by itself but is meant to be referenced
+  by device tree bindings.
+
+  When referenced from panel device tree bindings the properties defined in
+  this document are defined as follows. The panel device tree bindings are
+  responsible for defining whether each property is required or optional.
+
+  Notice: this binding concerns DSI panels connected directly to a master
+  without any intermediate port graph to the panel. Each DSI master
+  can control one to four virtual channels to one panel. Each virtual
+  channel should have a node "panel" for their virtual channel with their
+  reg-property set to the virtual channel number, usually there is just
+  one virtual channel, number 0.
+
+properties:
+  $nodename:
+    pattern: "^dsi-controller(@.*)?$"
+
+  "#address-cells":
+    const: 1
+
+  "#size-cells":
+    const: 0

+  "^panel@[0-3]$":
+    description: Panels connected to the DSI link
+    type: object
+
+    properties:
+      reg:
+        minimum: 0
+        maximum: 3
+        description:
+          The virtual channel number of a DSI peripheral. Must be in the range
+          from 0 to 3, as DSI uses a 2-bit addressing scheme. Some DSI
+          peripherals respond to more than a single virtual channel. In that
+          case the reg property can take multiple entries, one for each virtual
+          channel that the peripheral responds to.
+
+      clock-master:
+        type: boolean
+        description:
+           Should be enabled if the host is being used in conjunction with
+           another DSI host to drive the same peripheral. Hardware supporting
+           such a configuration generally requires the data on both the busses
+           to be driven by the same clock. Only the DSI host instance
+           controlling this clock should contain this property.
+
+      enforce-video-mode:
+        type: boolean
+        description:
+          The best option is usually to run a panel in command mode, as this
+          gives better control over the panel hardware. However for different
+          reasons like broken hardware, missing features or testing, it may be
+          useful to be able to force a command mode-capable panel into video
+          mode.

-Device-Tree bindings for tilcdc DRM TFP410 output driver

-Required properties:
- - compatible: value should be "ti,tilcdc,tfp410".
- - i2c: the phandle for the i2c device to use for DDC
-
-Recommended properties:
- - pinctrl-names, pinctrl-0: the pincontrol settings to configure
-   muxing properly for pins that connect to TFP410 device
- - powerdn-gpio: the powerdown GPIO, pulled low to power down the
-   TFP410 device (for DPMS_OFF)

-
-	dvicape {

-		pinctrl-names = "default";
-		pinctrl-0 = <&bone_dvi_cape_dvi_00A1_pins>;
