1SN65DSI86 DSI to eDP bridge chip
2--------------------------------
3
4This is the binding for Texas Instruments SN65DSI86 bridge.
5http://www.ti.com/general/docs/lit/getliterature.tsp?genericPartNumber=sn65dsi86&fileType=pdf
6
7Required properties:
8- compatible: Must be "ti,sn65dsi86"
9- reg: i2c address of the chip, 0x2d as per datasheet
10- enable-gpios: gpio specification for bridge_en pin (active high)
11
12- vccio-supply: A 1.8V supply that powers up the digital IOs.
13- vpll-supply: A 1.8V supply that powers up the displayport PLL.
14- vcca-supply: A 1.2V supply that powers up the analog circuits.
15- vcc-supply: A 1.2V supply that powers up the digital core.
16
17Optional properties:
18- interrupts-extended: Specifier for the SN65DSI86 interrupt line.
19
20- gpio-controller: Marks the device has a GPIO controller.
21- #gpio-cells    : Should be two. The first cell is the pin number and
22                   the second cell is used to specify flags.
23                   See ../../gpio/gpio.txt for more information.
24- #pwm-cells : Should be one. See ../../pwm/pwm.yaml for description of
25               the cell formats.
26
27- clock-names: should be "refclk"
28- clocks: Specification for input reference clock. The reference
29	  clock rate must be 12 MHz, 19.2 MHz, 26 MHz, 27 MHz or 38.4 MHz.
30
31- data-lanes: See ../../media/video-interface.txt
32- lane-polarities: See ../../media/video-interface.txt
33
34- suspend-gpios: specification for GPIO1 pin on bridge (active low)
35
36Required nodes:
37This device has two video ports. Their connections are modelled using the
38OF graph bindings specified in Documentation/devicetree/bindings/graph.txt.
39
40- Video port 0 for DSI input
41- Video port 1 for eDP output
