1 Toshiba TC358767 eDP bridge bindings
2
3 Required properties:
4  - compatible: "toshiba,tc358767"
5  - reg: i2c address of the bridge, 0x68 or 0x0f, depending on bootstrap pins
6  - clock-names: should be "ref"
7  - clocks: OF device-tree clock specification for refclk input. The reference
8    clock rate must be 13 MHz, 19.2 MHz, 26 MHz, or 38.4 MHz.

10 Optional properties:
11  - shutdown-gpios: OF device-tree gpio specification for SD pin
12                    (active high shutdown input)
13  - reset-gpios: OF device-tree gpio specification for RSTX pin
14                 (active low system reset)
15  - toshiba,hpd-pin: TC358767 GPIO pin number to which HPD is connected to (0 or 1)
16  - ports: the ports node can contain video interface port nodes to connect
17    to a DPI/DSI source and to an eDP/DP sink according to [1][2]:
18     - port@0: DSI input port
19     - port@1: DPI input port
20     - port@2: eDP/DP output port
