- Add binding doc
- Add imx91 thermal driver
- dts part wait for https://lore.kernel.org/imx/Z04W5chGq5TitB9f@lizhi-Precision-Tower-5810/
merged, so not in this serial.

Changes in v6:
- use set_trips
- remove mutex
- Link to v5: https://lore.kernel.org/r/[e-mail]

Changes in v5:
- Add irq support.
- change to period mode.
- Link to v4: https://lore.kernel.org/r/[e-mail]

Changes in v4:
- Add Kryz's review tag for binding
- Add Marco's review tag for driver
- Use devm_add_action()
- Move pm_runtim_put before thermal_of_zone_register()
- Link to v3: https://lore.kernel.org/r/[e-mail]

Changes in v3:
- add ref thermal-sensor
- restrict #thermal-sensor-cells to 0 only
- Change to unevaluatedProperties

- add IMX91_TMU_ prefix for register define
- remove unused register define
- fix missed pm_runtime_put() at error path in imx91_tmu_get_temp()
- use dev variable in probe function
- use pm_runtime_set_active() in probe
- move START to imx91_tmu_get_temp()
- use DEFINE_RUNTIME_DEV_PM_OPS()
- keep set reset value because there are not sw "reset" bit in controller,
  uboot may change and enable tmu.

- Link to v2: https://lore.kernel.org/r/[e-mail]

Changes in v2:
- use low case for hexvalue
- combine struct imx91_tmu and tmu_sensor
- simplify imx91_tmu_start() and imx91_tmu_enable()
- use s16 for imx91_tmu_get_temp(), which may negative value
- use reverse christmas tree style
- use run time pm
- use oneshot to sample temp
- register thermal zone after hardware init
- Link to v1: https://lore.kernel.org/r/[e-mail]
