As I have another series which is based on this one + Eagle board display
support, I'm re-sending this one to fix the small issue I pointed out in my
reply to v8.

Simon: no changes to Eagle DTS series, so the last one sent is still the good
one.

DRM: I have collected several reviewed-by tags both on driver and bindings.
Can I send out incremental patches on this series and consider this one to
be ready to be collected?

Thanks
   j

v8 -> v9:
- Put 'remote' OF node after usage not just in error path during device
  tree parsing routine
- Add Rob's Reviewed-by tag to the device tree bindings documentation

v7 -> b8:
- Make 'vcc' supply mandatory
- Use 'oe' property name to describe "OE" pin
- Minor fixes as suggested by Laurent on bindings and driver

v6 -> v7:
- Use semi-standard names for powerdown and output enable GPIOs as suggested
  by Rob and Vladimir
- Use 'regulator_get()' not the optional version, and list only 'vcc' as
  requested supply
- Addressed Laurent's review comments and removed Eagle display enablement patch
  to be sent separately

v5 -> v6:
- Drop check for CONFIG_OF as it is a Kconfig dependency
- Add Niklas Reviewed-by tags
- List [3/3] depenencies below commit message to ease integration

v4 -> v5:
- Fix punctuation in bindings documentation
- Add small statement to bindings document to clarify the chip has no
  control bus
- Print regulator name in enable/disable routines error path
- Add Andrzej Reviewed-by tag

v3 -> v4:
- Rename permutations of "pdwn" to just "pdwn" everywhere in the series
- Improve power enable/disable routines as suggested by Andrzej and Sergei
- Change "pdwn" gpio initialization to use the logical output level
- Change Kconfig description

v2 -> v3:
- Drop support for "lvds-decoder" and make the driver THC63LVD1024 specific
-- Rework bindings to describe multiple input/output ports
-- Rename driver and remove "lvds-decoder" references
-- Rework Eagle DTS to use new bindings

v1 -> v2:
- Drop support for THC63LVD1024

+Thine Electronics THC63LVD1024 LVDS decoder
+-------------------------------------------
+
+The THC63LVD1024 is a dual link LVDS receiver designed to convert LVDS streams
+to parallel data outputs. The chip supports single/dual input/output modes,
+handling up to two LVDS input streams and up to two digital CMOS/TTL outputs.
+
+Single or dual operation mode, output data mapping and DDR output modes are
+configured through input signals and the chip does not expose any control bus.
+
+Required properties:
+- compatible: Shall be "thine,thc63lvd1024"
+- vcc-supply: Power supply for TTL output, TTL CLOCKOUT signal, LVDS input,
+  PPL and digital circuitry
+
+Optional properties:
+- powerdown-gpios: Power down GPIO signal, pin name "/PDWN". Active low
+- oe-gpios: Output enable GPIO signal, pin name "OE". Active high
+
+The THC63LVD1024 video port connections are modeled according
+to OF graph bindings specified by Documentation/devicetree/bindings/graph.txt
+
+Required video port nodes:
+- port@0: First LVDS input port
+- port@2: First digital CMOS/TTL parallel output
+
+Optional video port nodes:
+- port@1: Second LVDS input port
+- port@3: Second digital CMOS/TTL parallel output
+
+Example:
+--------
+
+	thc63lvd1024: lvds-decoder {
+		compatible = "thine,thc63lvd1024";
+
+		vcc-supply = <&reg_lvds_vcc>;
+		powerdown-gpios = <&gpio4 15 GPIO_ACTIVE_LOW>;
+
+		ports {
+			#address-cells = <1>;
+			#size-cells = <0>;
+
+			port@0 {
+				reg = <0>;
+
+				lvds_dec_in_0: endpoint {
+					remote-endpoint = <&lvds_out>;
+				};
+			};
+
+			port@2{
+				reg = <2>;
+
+				lvds_dec_out_2: endpoint {
+					remote-endpoint = <&adv7511_in>;
+				};
+			};
