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 v2: https://lore.kernel.org/all/20250730152128.311109-1-laura.nao@collabora.com/ (local)

Changes in v3:
- Make ops in struct lvts_data a pointer to const struct lvts_platform_ops
- Changed mediatek,mt8188-efuse const entry in eFuse binding to an enum
with mediatek,mt8196-efuse and mediatek,mt8188-efuse, dropped mediatek,mt8196-efuse
const entry
Whole series is both

...and besides, this got also tested on MT8188/95 in our lab (for quite a while).
