Subject: [PATCH v7 0/7] Add support of New Amlogic temperature sensor for G12 SoCs

This patchs series add support of New Amlogic temperature sensor and minimal
thermal zone for SEI510 and ODROID-N2 boards.

First implementation was doing on IIO[1] but after comments i move on thermal framework.
Formulas and calibration values come from amlogic.

Changes since v6:
 - add missing critical trip point.

Changes since v5:
  - fix patch 5 and 6 send twice

Changes since v4:
  - Move thermal-zone in soc dtsi file
  - Remove critical trip point and add passive one
  - fix commit message
  - use devm_platform_ioremap_resource instead of platform_get_resource

Changes since v3:
  - Add cooling map and trip point for hot type
  - move compatible on g12a instead of g12 to be aligned with others
  - add all reviewer, sorry for this mistake

Changes since v2:
  - fix yaml documention
  - remove unneeded status variable for temperature-sensor node
  - rework driver after Martin review
  - add some information in commit message

Changes since v1:
  - fix enum vs const in documentation
  - fix error with thermal-sensor-cells value set to 1 instead of 0
  - add some dependencies needed to add cooling-maps

Dependencies :
- patch 3,4 & 5: depends on Neil's patch and series :
              - missing dwc2 phy-names[2]
              - patchsets to add DVFS on G12a[3] which have deps on [4] and [5]
