[PATCH v2 0/9] Add thermal sensor driver support for Mediatek MT8196
From: Laura Nao
Date: Wed Jul 30 2025 - 11:22:39 EST
This patch series extends the MediaTek LVTS thermal driver to support the
MT8196 SoC.
MT8196 requires a different implementation of the lvts_temp_to_raw()
function.
To support this, the series introduces:
- A new struct lvts_platform_ops to allow platform-specific
conversion logic between raw sensor values and temperature
- A variant of the lvts_temp_to_raw() implementation
- Platform data and controller definitions for MT8196
Link to v1: https://lore.kernel.org/all/20250721081459.16278-1-laura.nao@xxxxxxxxxxxxx/
Changes in v2:
- Added a warning in the probe function for temp_factor==0
- Reworded message for commit adding the lvts_temp_to_raw() variant
- Replaced mode macros with an enum
- Fixed eFuse binding to reflect compatibility with MT8186
