[PATCH v6 0/6] Mediatek thermal sensor driver support for MT8186 and MT8188
From: Julien Panis
Date: Wed May 29 2024 - 01:58:12 EST
This is a bunch of patches to support the MT8186 and MT8188 thermal
sensor configurations.
Since the patches of v3 were applied except those related to the SoC
device trees, this series includes mainly patches for 'mt8186.dtsi'
and 'mt8188.dtsi'. Due to some thermal zone renaming in these 2 device
trees, the related definitions were also renamed in the dt-bindings and
in the driver.
Because of the GPU thermal zone, this series must be applied on top of [1].

Changes in v6:
- Reorganize patches related to thermal zone renaming (dt-bindings + driver).
- Add cooling-cells property to GPU node in 'mt8188.dtsi'
- Link to v5: https://lore.kernel.org/r/20240524-mtk-thermal-mt818x-dtsi-v5-0-56f8579820e7@xxxxxxxxxxxx
Changes in v5:
- Rename some thermal zones
(mfg -> gpu / soc1 -> adsp / soc2 -> vdo / soc3 -> infra).
- Add cooling-device for GPUs.
- Link to v4: https://lore.kernel.org/r/20240521-mtk-thermal-mt818x-dtsi-v4-0-b91ee678411c@xxxxxxxxxxxx
Changes in v4:
- Fix wrong thermal zone names.
- Lower 'polling-delay-passive' values.
- Set 'hysteresis' value to 0 for 'critical' trips.
- Add a 'hot' trip point in between 'passive' and 'critical' trips.
- Link to v3: https://lore.kernel.org/all/20240402032729.2736685-1-nico@xxxxxxxxxxx/
Changes in v3:
- use meaningful name for binding index definitions
- reuse LVTS_COEFF_*_MT7988 on MT8186 per reviewer request
- do similarly for MT8188 that now reuses LVTS_COEFF_*_MT8195
- use thermal zone names the svs driver wants
- adjust some DT node names and iospace length
- remove variable .hw_tshut_temp as it is constant across all SOCs
- Link to v2: https://lore.kernel.org/all/20240318212428.3843952-1-nico@xxxxxxxxxxx/
Changes in v2:
- renamed CPU cluster thermal zones in DT
- fixed logic to cope with empty controller slots at the beginning
- isolated bindings to their own patches
- added MT8188 default thermal zones
- Link to v1: https://lore.kernel.org/all/20240111223020.3593558-1-nico@xxxxxxxxxxx/T/
