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. [1] https://patchwork.kernel.org/project/linux-mediatek/cover/20200306041345.259332-1-drinkcat@chromium.org/ [2] https://crrev.com/c/2608070 Changes in v11: - binding: power-domain-names not power-domainS-names - mt8183*.dts: remove incorrect supply-names Changes in v10: - Fix the binding to make sure sram-supply property can be provided. Changes in v9: - Explain why devfreq needs to be disabled for GPUs with >1 regulators. Changes in v8: - Use DRM_DEV_INFO instead of ERROR Changes in v7: - Fix GPU ID in commit message - Fix GPU ID in commit message Changes in v6: - Rebased, actually tested with recent mesa driver. - Add gpu regulators to kukui dtsi as well. - Power domains are now attached to spm, not scpsys - Drop R-B. - devfreq: New change - Context conflicts, reflow the code. - Use ARRAY_SIZE for power domains too. Changes in v5: - Rename "2d" power domain to "core2" - Rename "2d" power domain to "core2" (keep R-B again). - Change power domain name from 2d to core2. Changes in v4: - Add power-domain-names description (kept Alyssa's reviewed-by as the change is minor) - Add power-domain-names to describe the 3 domains. (kept Alyssa's reviewed-by as the change is minor) - Add power domain names. Changes in v3: - Match mt8183-mali instead of bifrost, as we require special handling for the 2 regulators and 3 power domains. Changes in v2: - Use sram instead of mali_sram as SRAM supply name. - Rename mali@ to gpu@.
