Add VTM thermal support. In the Voltage Thermal
Management Module(VTM), K3 AM654 supplies a voltage
reference and a temperature sensor feature that are gathered in the band
gap voltage and temperature sensor (VBGAPTS) module. The band
gap provides current and voltage reference for its internal
circuits and other analog IP blocks. The analog-to-digital
converter (ADC) produces an output value that is proportional
to the silicon temperature.
Add support for bandgap sensors. Currently reading temperatures
is supported.
How do you want to proceed? Shall I take patches 1 & 2 ?

Hi Tero,
Can you pull 3 & 4? Or Daniel can take all 4?
Let me pull the DT patches, that way we avoid any conflicts in the
arm64/dts tree. There has been quite a bit of traffic on that front
lately and we did mess up something with the current merge window already.
I believe you are picking the driver side changes to 5.8?

Changes in v6:
* Removed bunch of unused #defines and couple of redundant variables.
* Reordered patches a bit.
* Minor reordering in dt binding patch.
Changes in v5:
* Removed thermal work function which was unused.
* Removed unused preve_tenmp and a couple more struct variables.
* Removed couple of redundant header function include.
Changes in v4:
* Fixed comments from Daniel to remove trend function.
* Mostly cleaned up all the unused variables.
* Driver from bool to tristate.
Changes in v3:
* Fixed errors seen with:
dt_binding_check
DT_SCHEMA_FILES=Documentation/devicetree/bindings/thermal/ti,am654-thermal.yaml
Changes in v2:
* Fixed yaml errors
* renamed am654-industrial-thermal.dtsi to
k3-am654-industrial-thermal.dtsi
to follow the convention for k3 family.
