[PATCH v5 1/2] dt-bindings: panel: Add Sitronix ST7701 panel documentation
From: Jagan Teki
Date: Tue Dec 11 2018 - 11:22:19 EST
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.
Signed-off-by: Jagan Teki <jagan@xxxxxxxxxxxxxxxxxxxx>
Changes for v5:
- found the chip from vendor, so added new chip binding
- here is v4: https://patchwork.kernel.org/patch/10680333/

+Sitronix ST7701 based LCD panels
+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.
+- compatible: must be "sitronix,st7701" and one of

+- 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
+- backlight: phandle for the backlight control.
