Subject: [PATCH v3 25/25] arm64: dts: allwinner: a64-amarula-relic: Enable Techstar TS8550B MIPI-DSI panel
Date: Fri, 26 Oct 2018 20:13:44 +0530 [thread overview]
Message-ID: <20181026144344.27778-26-jagan@amarulasolutions.com> (raw)
In-Reply-To: <20181026144344.27778-1-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,
- DC1SW as AVDD supply
- DCDC2 as DVDD supply
- DCDC1 as VCC-DSI supply
- PD24 gpio for reset pin
- PD23 gpio for backlight enable pin
