Subject: [PATCH v6 22/22] arm64: dts: allwinner: a64-amarula-relic: Add Techstar TS8550B MIPI-DSI panel
Date: Fri, 25 Jan 2019 01:29:00 +0530
Message-ID: <20190124195900.22620-23-jagan@amarulasolutions.com> (raw)
In-Reply-To: <20190124195900.22620-1-jagan@amarulasolutions.com>

Amarula A64-Relic board by default bound with Techstar TS8550B
MIPI-DSI panel, add support for it.

DSI panel connected via board DSI port with,
- DLDO2 as VCC supply
- DLDO2 as IOVCC supply
- DLDO1 as VCC-DSI supply
- PD24 gpio for reset pin
- PD23 gpio for backlight enable pin
