The only capability of the Armada thermal driver is currently just to
read one sensor (the default one) per AP and one per CP. Actually,
there is one sensor per core in the AP806 plus one sensor in the
thermal IP itself. The CP110 just features one thermal sensor in its
own thermal IP.
This series first improves the readability of this driver, then adds
support for multi-channel thermal IPs. The bindings and the
device-trees are updated accordingly.
Eduardo, this is a barely modified version of my previous series
adding overheat interrupt support. All the interrupt-related patches
have been dropped for now. It is now only rewording, reorganization
and multi-sensor support being added here; there is no more
dependency. As I did not receive any feedback since April, 24th I
would like it to be merged for 4.19.
Thank you,
Miquèl
Changes since v1:
=================
* Added register ranges in the thermal nodes.
* Added these ranges in the documentation also.
* In the bindings, used the "Must be one of" formula before listing the
compatibles.
* Removed the overheat interrupt support that depends on another
series. This work is independent.
* Rebased on top of v4.18-rc1.
