Subject[PATCH v4 6/7] RFC: drm/panfrost: Add mt8183-mali compatible string
Date
For testing only, the driver doesn't really work yet, AFAICT.

Signed-off-by: Nicolas Boichat <drinkcat@chromium.org>

---

v4:
- Add power domain names.
v3:
- Match mt8183-mali instead of bifrost, as we require special
handling for the 2 regulators and 3 power domains.
