[PATCH 0/9] Add thermal sensor driver support for Mediatek MT8196

This patch series extends the MediaTek LVTS thermal driver to support the
MT8196 SoC.

MT8196 uses a positive temp_factor for temperature conversion, requiring
slight adjustments in the conversion logic.

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 for SoCs with positive
  temp_factor values
- Platform data and controller definitions for MT8196
