From: Frank Wunderlich <frank-w@public-files.de>
Add Support for Mediatek Filogic 880/MT7988 LVTS.
Signed-off-by: Frank Wunderlich <frank-w@public-files.de>
---
v3:
- drop comments
v2:
- use 105°C for hw shutdown
- move constants to binding file
- change coeff.a to temp_factor and coeff.b to temp_offset
- change to lvts to lvts-ap (Application Processor)
- drop comments about efuse offsets
- change comment of mt8195 to be similar to mt7988
