Subject: [PATCH v12 6/7] arm64: dts: allwinner: a64: Add MIPI DSI pipeline
Date: Tue, 3 Dec 2019 19:18:15 +0530 [thread overview]
Message-ID: <20191203134816.5319-7-jagan@amarulasolutions.com> (raw)
In-Reply-To: <20191203134816.5319-1-jagan@amarulasolutions.com>
Add MIPI DSI pipeline for Allwinner A64.
- dsi node, with A64 compatible since it doesn't support
DSI_SCLK gating unlike A33
- dphy node, with A64 compatible with A33 fallback since
DPHY on A64 and A33 is similar
- finally, attach the dsi_in to tcon0 for complete MIPI DSI
