[PATCH v4 0/6] thermal: tegra: add SOCTHERM support for Tegra114

[PATCH v4 0/6] thermal: tegra: add SOCTHERM support for Tegra114

[Svyatoslav Ryhel]

SOCTHERM is thermal sensor and thermal throttling controller found in Tegra
SoC starting from Tegra114. Existing Tegra124 setup is mostly compatible
with Tegra114 and needs only a few slight adjustmets of fuse calibration
process.

---
Changes in v2:
- no changes, resend.

Changes in v3:
- expanded desciption of "thermal: tegra: soctherm-fuse: parametrize
  configuration further" commit
- changes title of "thermal: tegra: soctherm-fuse: parametrize
  configuration further" to "thermal: tegra: soctherm-fuse: prepare
  calibration for Tegra114 support"
- Tegra11x > Tegra114 and Tegra12x > Tegra124
- ft and cp shift bits dropped
- clarified tegra114 precision
- lower_precision > use_lower_precision
- nominal calibration ft and cp hardcoded into SoC specific structures
- added tegra114-soctherm header into dt-bindings

Changes in v4:
- fixed Tegra124/132/210 cp mask
- dropped TEGRA114_SOCTHERM_SENSOR_NUM from header
- TEGRA_SOCTHERM_THROT_LEVEL_ made SoC specific
- adjusted soctherm node and inclusions in tegra114.dtsi
- dropped use_lower_presision and nominal_calib_cp options

[PATCH v4 3/6] thermal: tegra: soctherm-fuse: prepare calibration for Tegra114 support

[Svyatoslav Ryhel]

The Tegra114 has a different fuse calibration register layout and address
compared to other Tegra SoCs, requiring SOCTHERM shift, mask, register
address, and nominal tf calibration value to be configurable.

In L4T r17, I see the hotspot offset values for both CPU and GPU at 6000 (i.e. 
6 for upstream).

Also, I notice that the driver is relying on the TEGRA124_* DT bindings for 
internal indexing, hence requiring that TEGRA114_* values are the same. While 
that should really hold, I think it'd be a good touch to add some 
static_assert()s to assert the TEGRA114_* and TEGRA124_* counterparts are 
equal.

Otherwise, looks good to me!

Thanks,
Mikko
