Subject: [PATCH 0/9] Panfrost: Improve and add MediaTek SoCs support
Date:   Wed,  8 Feb 2023 11:37:00 +0100

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.

Alyssa Rosenzweig (3):
  drm/panfrost: Increase MAX_PM_DOMAINS to 5
  drm/panfrost: Add the MT8192 GPU ID
  drm/panfrost: Add mediatek,mt8192-mali compatible

AngeloGioacchino Del Regno (6):
  dt-bindings: gpu: mali-bifrost: Don't allow sram-supply by default
  dt-bindings: gpu: mali-bifrost: Allow up to 5 power domains for MT8192
  dt-bindings: gpu: mali-bifrost: Add compatible for MT8195 SoC
  dt-bindings: gpu: mali-bifrost: Add new MT8183 compatible
  dt-bindings: gpu: mali-bifrost: Add a compatible for MediaTek MT8186
  drm/panfrost: Add new compatible for Mali on the MT8183 SoC
