+Device-Tree bindings for LVDS Display Bridge (ldb)
+
+LVDS Display Bridge
+===================
+
+The LVDS Display Bridge device tree node contains up to two lvds-channel
+nodes describing each of the two LVDS encoder channels of the bridge.
+
+Required properties:
+ - #address-cells : should be <1>
+ - #size-cells : should be <0>
+ - compatible : should be "fsl,imx53-ldb" or "fsl,imx6q-ldb".
+                Both LDB versions are similar, but i.MX6 has an additional
+                multiplexer in the front to select any of the four IPU display
+                interfaces as input for each LVDS channel.
+ - gpr : should be <&gpr> on i.MX53 and i.MX6q.
+         The phandle points to the iomuxc-gpr region containing the LVDS
+         control register.
+- clocks, clock-names : phandles to the LDB divider and selector clocks and to
+                        the display interface selector clocks, as described in
+                        Documentation/devicetree/bindings/clock/clock-bindings.txt
+        The following clocks are expected on i.MX53:
+                "di0_pll" - LDB LVDS channel 0 mux
+                "di1_pll" - LDB LVDS channel 1 mux
+                "di0" - LDB LVDS channel 0 gate
+                "di1" - LDB LVDS channel 1 gate
+                "di0_sel" - IPU1 DI0 mux
+                "di1_sel" - IPU1 DI1 mux
+        On i.MX6q the following additional clocks are needed:
+                "di2_sel" - IPU2 DI0 mux
+                "di3_sel" - IPU2 DI1 mux
+        The needed clock numbers for each are documented in
+        Documentation/devicetree/bindings/clock/imx5-clock.yaml, and in
+        Documentation/devicetree/bindings/clock/imx6q-clock.yaml.
+
+Optional properties:
+ - pinctrl-names : should be "default" on i.MX53, not used on i.MX6q
+ - pinctrl-0 : a phandle pointing to LVDS pin settings on i.MX53,
+               not used on i.MX6q
+ - fsl,dual-channel : boolean. if it exists, only LVDS channel 0 should
+   be configured - one input will be distributed on both outputs in dual
+   channel mode
+
+LVDS Channel
+============
+
+Each LVDS Channel has to contain either an of graph link to a panel device node
+or a display-timings node that describes the video timings for the connected
+LVDS display as well as the fsl,data-mapping and fsl,data-width properties.
+
+Required properties:
+ - reg : should be <0> or <1>
+ - port: Input and output port nodes with endpoint definitions as defined in
+   Documentation/devicetree/bindings/graph.txt.
+   On i.MX5, the internal two-input-multiplexer is used. Due to hardware
+   limitations, only one input port (port@[0,1]) can be used for each channel
+   (lvds-channel@[0,1], respectively).
+   On i.MX6, there should be four input ports (port@[0-3]) that correspond
+   to the four LVDS multiplexer inputs.
+   A single output port (port@2 on i.MX5, port@4 on i.MX6) must be connected
+   to a panel input port. Optionally, the output port can be left out if
+   display-timings are used instead.
+
+Optional properties (required if display-timings are used):
+ - ddc-i2c-bus: phandle of an I2C controller used for DDC EDID probing
+ - display-timings : A node that describes the display timings as defined in
+   Documentation/devicetree/bindings/display/panel/display-timing.txt.
+ - fsl,data-mapping : should be "spwg" or "jeida"
+                      This describes how the color bits are laid out in the
+                      serialized LVDS signal.
+ - fsl,data-width : should be <18> or <24>
+
+example:
+
+gpr: iomuxc-gpr@53fa8000 {
+	/* ... */
+};
+
+ldb: ldb@53fa8008 {

+title: iMX8MQ Display Controller Subsystem (DCSS)
+
+maintainers:
+  - Laurentiu Palcu <laurentiu.palcu@nxp.com>
+
+description:
+
+  The DCSS (display controller sub system) is used to source up to three
+  display buffers, compose them, and drive a display using HDMI 2.0a(with HDCP
+  2.2) or MIPI-DSI. The DCSS is intended to support up to 4kp60 displays. HDR10
+  image processing capabilities are included to provide a solution capable of
+  driving next generation high dynamic range displays.
