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.txt 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
|
||
|
|
|
||
|
