Subject[PATCH v13 6/7] arm64: dts: allwinner: a64: Add MIPI DSI pipeline
Date
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
