Changes in v5:
- Changed minItems for power-domain-names in base schema as
suggested by Rob
Changes in v4:
- Refactored power-domains and power-domain-names exclusions as
suggested by Krzysztof
- Small changes in MT8192 bindings addition
Changes in v3:
- Changed MT8186 bindings to declare only two power domains
- Added a commit introducing MT8186 specific platform data to
panfrost_drv
Changes in v2:
- Add power-domain-names commit from Chen-Yu to the series
- Kept sram-supply in base schema, overridden for non-MediaTek
- Added Reviewed-by tags from Steven Price to the driver commits
(as released in reply to v1's cover letter - thanks!)
This series adds support for new MediaTek SoCs (MT8186/MT8192/MT8195)
and improves MT8183 support: since the mtk-regulator-coupler driver
was picked, it is now useless for Panfrost to look for, and manage,
two regulators (GPU Vcore and GPU SRAM) on MediaTek;
The aforementioned driver will take care of keeping the voltage
relation (/constraints) of the two regulators on its own when a
voltage change request is sent to the Vcore, solving the old time
issue with not working DVFS on Panfrost+MediaTek (due to devfreq
supporting only single regulator).
In the specific case of MT8183, in order to not break the ABI, it
was necessary to add a new compatible for enabling DVFS.
