Follow-up on the v5 [1], things have gotten significantly better in the last 9 months, thanks to the efforts on Bifrost support by the Collabora team (and probably others I'm not aware of). I've been testing this series on a MT8183/kukui device, with a chromeos-5.10 kernel [2], and got basic Chromium OS UI up with mesa 20.3.2 (lots of artifacts though). devfreq is currently not supported, as we'll need: - Clock core support for switching the GPU core clock (see 2/4). - Platform-specific handling of the 2-regulator (see 3/4). Since the latter is easy to detect, patch 3/4 just disables devfreq if the more than one regulator is specified in the compatible matching table.
