Subject: [PATCH v3 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 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/

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

Laura Nao (9):
  dt-bindings: thermal: mediatek: Add LVTS thermal controller support
    for MT8196
  thermal/drivers/mediatek/lvts: Make number of calibration offsets
    configurable
  thermal/drivers/mediatek/lvts: Guard against zero temp_factor in
    lvts_raw_to_temp
  thermal: mediatek: lvts: Add platform ops to support alternative
    conversion logic
  thermal/drivers/mediatek/lvts: Add lvts_temp_to_raw variant
  thermal/drivers/mediatek/lvts: Add support for ATP mode
  thermal/drivers/mediatek/lvts: Support MSR offset for 16-bit
    calibration data
  thermal/drivers/mediatek/lvts_thermal: Add MT8196 support
  dt-bindings: nvmem: mediatek: efuse: Add support for MT8196
