Subject: [PATCH v2] dt-bindings: display/bridge: tc358764: Convert to YAML binding
Convert the Toshiba TC358764 txt documentation to YAML.
Signed-off-by: AngeloGioacchino Del Regno <angelogioacchino.delregno@...labora.com>

Note: dtbs_check on exynos5250-arndale.dts will give some warnings after
applying this patch: since the preferred way is to have 'ports',
this warning was ignored.
I have no Exynos5250 board, so the dts fix is left to someone who
is able to test on the real hw.

-TC358764 MIPI-DSI to LVDS panel bridge
-
-Required properties:
- - compatible: "toshiba,tc358764"
- - reg: the virtual channel number of a DSI peripheral
- - vddc-supply: core voltage supply, 1.2V
- - vddio-supply: I/O voltage supply, 1.8V or 3.3V
- - vddlvds-supply: LVDS1/2 voltage supply, 3.3V
- - reset-gpios: a GPIO spec for the reset pin
-
-The device node can contain following 'port' child nodes,
-according to the OF graph bindings defined in [1]:
- 0: DSI Input, not required, if the bridge is DSI controlled
- 1: LVDS Output, mandatory
-
-[1]: Documentation/devicetree/bindings/media/video-interfaces.txt
-
-Example:
-
- bridge@0 {
- reg = <0>;
- compatible = "toshiba,tc358764";
- vddc-supply = <&vcc_1v2_reg>;
- vddio-supply = <&vcc_1v8_reg>;
- vddlvds-supply = <&vcc_3v3_reg>;
- reset-gpios = <&gpd1 6 GPIO_ACTIVE_LOW>;
- #address-cells = <1>;

- port@1 {
- reg = <1>;
- lvds_ep: endpoint {
