This patch series extends the MediaTek LVTS thermal driver to support the
MT8196 SoC.
This series has been there on the lists for *5 months* now, and it still
applies as-is.

Can we *please* get this picked?

Thanks,
Angelo
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 v4: https://lore.kernel.org/r/20251121-mt8196-lvts-v4-v4-0-357f955a3176@collabora.com (local)

Changes in v5:
- Dropped patch 3
- Added LVTS_NUM_CAL_OFFSETS_MT7988/LVTS_NUM_CAL_OFFSETS_MT8196 defines
- Moved code that assembles calibration bytes from the efuse data into
   a dedicated lvts_decode_sensor_calibration() helper
- Fixed prefix in patch 4 commit message
- Dropped R-b/T-b tags on patch 2
