[PATCH v3 0/7] thermal: rcar_gen3_thermal: add support for interrupt triggerd trip points

["Niklas Söderlund" <niklas.soderlund+renesas@ragnatech.se>]

Hi,

This series adds support for hardware backed trip point windows. It is
based on top of v4.11-rc1 and is tested on R-Car H3 and M3-W.

The series starts out by fixing three issues (1/7, 2/7, 3/7) that should
have been fixed by me before the initial driver where submitted to
upstream. Sorry for not spotting the issues sooner.

The series then extends the rcar_gen3_thermal driver with hardware
interrupts for trip point windows by implementing the .set_trips()
callback of struct thermal_zone_of_device_ops (4/7, 5/7). It then adds
suspend and resume handlers so that the hardware interrupts are
preserved across suspend/resume cycles (6/7, 7/7).

* Changes since v2
- Corrected spelling
- Collected Reviewed-by tags
- Move num_tscs to bellow the pointers inside struct 
  rcar_gen3_thermal_priv to avoid implicit gap
- Assign num_tscs after the TSCs loop instead of increment it once each 
  loop iteration.
- Use bool instead of int for on parameter in rcar_thermal_irq_set()
- Merge 'val' variable declaration and assignment in 
  rcar_thermal_irq_set().
- Use spin_lock instead of spin_lock_irqsave in the ISR.
- Add comment about that the driver only uses 2 of the 3 available c
  interrupts.

* Changes since v1
- Added check that at least one TSC is found
- Record number of TSC in private data structure
- Request interrupts separately from TSCs
- Have only one function which controls both IRQ on and off
- Check return value from of_thermal_get_ntrips()
- Fixed spelling in commit messages
- Add Reviewed-by tags
