[PATCH v5 3/4] RFC: drm/panfrost: Add mt8183-mali compatible string

From: Nicolas Boichat
Date: Thu Mar 05 2020 - 23:14:18 EST


For testing only, the driver doesn't really work yet, AFAICT.

v5:
- Change power domain name from 2d to core2.
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.
