This is another series of tsens cleanups before we add interrupt support. This applies on top of 4.19-rc2.

Patches [1-6] can directly be applied by Eduardo.
Patches [9-16] can directly be applied by Andy.
Patches [7-8] introduce a new check and needs review and can then be
applied completely separately by Eduardo. 

There is a *dependency* however. Patch 1 should be applied to the tree
before the DT changes in patches 9 and 10.

In this series, I've collected all outstanding tsens patches by combining
the patches from the v2 posting with 3 DT patches for sdm845 thermal zones
and msm8916 camera and gpu thermal zones. Details are as follows:

- splitup 8916 and 8974 register address spaces for SROT and TM
- cleanups: move to spdx, dead code removal, removal of id field
- Add support to map the SROT address space for DTs that list it separately
- Check if TSENS IP is enabled in firmware by querying the SROT space
- Add myself as maintainer of tsens
- Add one-off patches adding sdm845 thermal zones and msm8916 gpu and
  camera thermal zones to this series.

Changes since v2:
- Split up changes to code and dt and within dt, split into arm and arm64
  patches
- Rearrange the sequence of patches so that the thermal maintainer can pick
  up the first part and the platform maintainer can pick up the latter part
  of the series
- Drop patch 09/11 because it causes some issues on systems with
  non-contiguous enabled sensors e.g. db410c
- Drop patch 10/11 because reg-name property isn't encouraged
- Fix a bug on msm8916 to check if IP is enabled in firmware. This was due
  to the register being at a different offset on msm8916. Fixed by coding
  this information as private data.

Changes since v1:
- Split up changes that split the address space and added qcom,sensors
  property into two separate patches
- Remove brackets in typo correction patch

To clarify here, it might be easier if Eduardo acks patches 9 and 10
so that they can be merged through Andy's tree before the rest of the
DT patches. That would remove the need to create any immutable trees
or having to worry about the ordering of the patches.

Just a suggestion.

Eduardo,

I ACKed the DTS patches for this.  Can you take 9-16 along with the 1-6 through
your tree?

Thanks,

Andy

Thanks Andy.

Eduardo, I've send a fixup patch 07/16. If you like, I can resend the
entire series
or you can find the entire series hosted with all tags applied here:

Amit
