dt-bindings: display: Add Sitronix ST7701 panel documentation 



Techstar TS8550B MIPI DSI panel is 480x854, 2-lane MIPI DSI LCD panel
with inbuilt ST7701 chip.

The default regulator names in ST7701 chip is renamed in Techstar TS8550B
so, add specific binding names for them.

ST7701 designed for small and medium sizes of TFT LCD display, is

capable of supporting up to 480RGBX864 in resolution. It provides

several system interfaces like MIPI/RGB/SPI.



Techstar TS8550B is 480x854, 2-lane MIPI DSI LCD panel which has

inbuilt ST7701 chip.



Required properties:

- compatible: must be "sitronix,st7701" and one of

  * "techstar,ts8550b"

- reset-gpios: a GPIO phandle for the reset pin



Required properties for techstar,ts8550b:

- reg: DSI virtual channel used by that screen

- VCC-supply: analog regulator for MIPI circuit

- IOVCC-supply: I/O system regulator



Optional properties:

- backlight: phandle for the backlight control.
