[PATCH v9 1/2] dt-bindings: panel: Add Sitronix ST7701 panel documentation

From: Jagan Teki
Date: Thu Jan 24 2019 - 16:51:47 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.
