Toshiba TC358767 eDP bridge bindings
|
|
|
|
Required properties:
|
|
- compatible: "toshiba,tc358767"
|
|
- reg: i2c address of the bridge, 0x68 or 0x0f, depending on bootstrap pins
|
|
- clock-names: should be "ref"
|
|
- clocks: OF device-tree clock specification for refclk input. The reference
|
|
clock rate must be 13 MHz, 19.2 MHz, 26 MHz, or 38.4 MHz.
|
|
|
|
Optional properties:
|
|
- shutdown-gpios: OF device-tree gpio specification for SD pin
|
|
(active high shutdown input)
|
|
- reset-gpios: OF device-tree gpio specification for RSTX pin
|
|
(active low system reset)
|
|
- toshiba,hpd-pin: TC358767 GPIO pin number to which HPD is connected to (0 or 1)
|
|
- ports: the ports node can contain video interface port nodes to connect
|
|
to a DPI/DSI source and to an eDP/DP sink according to [1][2]:
|
|
- port@0: DSI input port
|
|
- port@1: DPI input port
|
|
- port@2: eDP/DP output port
