[PATCH 1/3] dt-bindings: drm/bridge: ti-sn65dsi86: Convert to yaml
From: Douglas Anderson
Date: Wed Apr 15 2020 - 11:50:04 EST
This moves the bindings over, based a lot on toshiba,tc358768.yaml.
Unless there's someone known to be better, I've set the maintainer in
the yaml as the first person to submit bindings.

-SN65DSI86 DSI to eDP bridge chip
---------------------------------
-
-This is the binding for Texas Instruments SN65DSI86 bridge.
-http://www.ti.com/general/docs/lit/getliterature.tsp?genericPartNumber=sn65dsi86&fileType=pdf
-
-Required properties:
-- compatible: Must be "ti,sn65dsi86"
-- reg: i2c address of the chip, 0x2d as per datasheet
-- enable-gpios: gpio specification for bridge_en pin (active high)
-
-- vccio-supply: A 1.8V supply that powers up the digital IOs.
-- vpll-supply: A 1.8V supply that powers up the displayport PLL.
-- vcca-supply: A 1.2V supply that powers up the analog circuits.
-- vcc-supply: A 1.2V supply that powers up the digital core.
-
-Optional properties:
-- interrupts-extended: Specifier for the SN65DSI86 interrupt line.
-
-- gpio-controller: Marks the device has a GPIO controller.
-- #gpio-cells : Should be two. The first cell is the pin number and
- the second cell is used to specify flags.
- See ../../gpio/gpio.txt for more information.
-- #pwm-cells : Should be one. See ../../pwm/pwm.yaml for description of
- the cell formats.
-
-- clock-names: should be "refclk"
-- clocks: Specification for input reference clock. The reference
- clock rate must be 12 MHz, 19.2 MHz, 26 MHz, 27 MHz or 38.4 MHz.
-
-- data-lanes: See ../../media/video-interface.txt
-- lane-polarities: See ../../media/video-interface.txt
-
-- suspend-gpios: specification for GPIO1 pin on bridge (active low)
-
-Required nodes:
-This device has two video ports. Their connections are modelled using the
-OF graph bindings specified in Documentation/devicetree/bindings/graph.txt.
-
-- Video port 0 for DSI input
-- Video port 1 for eDP output
-
