[PATCH v2 7/8] drm/msm/dpu: add SM8150 to hw catalog

Jonathan Marek
2020-07-11T00:50:30Z

This brings up basic video mode functionality for SM8150 DPU. Command mode
and dual mixer/intf configurations are not working, future patches will
address this. Scaler functionality and multiple planes is also untested.
