Subject: [PATCH v6 1/2] dt-bindings: panel: Add Sitronix ST7701 panel documentation
Date: Sat, 15 Dec 2018 02:16:39 +0530	[thread overview]
Message-ID: <20181214204640.9789-1-jagan@amarulasolutions.com> (raw)

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.
