[v7,0/3] mt8183: Add Mediatek thermal driver and dtsi

From: Michael Kao

This patchset supports for MT8183 chip to mtk_thermal.c.
Add thermal zone of all the thermal sensor in SoC for
another get temperatrue. They don't need to thermal throttle.
And we bind coolers for thermal zone nodes of cpu_thermal.

Changes in v7:
- Fix build error in v6.

Changes in v6:
- Rebase to kernel-5.11-rc1.
- [1/3]
- add interrupts property.
- [2/3]
- add the Tested-by in the commit message.
- [3/3]
- use the mt->conf->msr[id] instead of conf->msr[id] in the
_get_sensor_temp and mtk_thermal_bank_temperature.
- remove the redundant space in _get_sensor_temp and
mtk_read_sensor_temp.
- change kmalloc to dev_kmalloc in mtk_thermal_probe.

Changes in v5:
- Rebase to kernel-5.9-rc1.
- Revise the title of cover letter.
- Drop "[v4,7/7] thermal: mediatek: use spinlock to protect PTPCORESEL"
- [2/2]
- Add the judgement to the version of raw_to_mcelsius.

Changes in v4:
- Rebase to kernel-5.6-rc1.
- [1/7]
- Squash thermal zone settings in the dtsi from [v3,5/8]
arm64: dts: mt8183: Increase polling frequency for CPU thermal zone.
- Remove the property of interrupts and mediatek,hw-reset-temp.
- [2/7]
- Correct commit message.
- [4/7]
- Change the target temperature to the 80C and change the commit message.
- [6/7]
- Adjust newline alignment.
- Fix the judgement on the return value of registering thermal zone.

Changes in v3:
- Rebase to kernel-5.5-rc1.
- [1/8]
- Update sustainable power of cpu, tzts1~5 and tztsABB.
- [7/8]
- Bypass the failure that non cpu_thermal sensor is not find in thermal-zones
in dts, which is normal for mt8173, so prompt a warning here instead of
failing.

Return -EAGAIN instead of -EACCESS on the first read of sensor that
often are bogus values. This can avoid following warning on boot:

thermal thermal_zone6: failed to read out thermal zone (-13)

Changes in v2:
- [1/8]
- Add the sustainable-power,trips,cooling-maps to the tzts1~tztsABB.
- [4/8]
- Add the min opp of cpu throttle.
