This series fixes interrupt handling in the LVTS thermal driver. It not
only solves the interrupt storms currently happening, but also allows
the temperature monitoring interrupts to trigger when the thermal trip
temperature is reached.
This series was tested together with the MT8192 support series [1] on
the Spherion Chromebook (mt8192-asurada-spherion).
These are standalone fixes and don't depend on anything else.

Changes in v3:
- Reworded cover letter
- Split bitmaps for immediate and filtered modes into separate arrays
(patch 2)
- Removed duplicate code for setting MINIMUM_THRESHOLD (patch 5)
Changes in v2:
- Added commits 3, 5, 6 to get working interrupts when crossing thermal
trip points
- Updated commit 4 with interrupt flags for the offset
Nícolas F. R. A. Prado (6):
thermal/drivers/mediatek/lvts_thermal: Handle IRQ on all controllers
thermal/drivers/mediatek/lvts_thermal: Honor sensors in immediate mode
thermal/drivers/mediatek/lvts_thermal: Use offset threshold for IRQ
thermal/drivers/mediatek/lvts_thermal: Disable undesired interrupts
thermal/drivers/mediatek/lvts_thermal: Don't leave threshold zeroed
thermal/drivers/mediatek/lvts_thermal: Manage threshold between
sensors
