Subject: arm64: dts: allwinner: a64: Add MIPI DSI pipeline
|
|
|
|
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
