Subject: [PATCH v7 0/7] thermal: tsens: Refactoring for TSENSv2 IP

This series is a mixed bag:
- Some code moves to allow code sharing between different SoCs with v2 of
  the TSENS IP,
- a generic qcom,tsens-v2 property as a fallback compatible for all v2.x.y
- new platform support (sdm845)
- a cleanup patch and
- a DT change to have a common way to deal with the SROT and TM registers
  despite slightly different features across the IP family and different
  register offsets.

Changes since v6:
- Fix comments and patch descriptions as per Doug's review
- Rename tsens to thermal-sensor in DT
- Add various review tags

Changes since v5:
- Actually fix unit addressses for the two tsens blocks as per Stephen's comment.

Changes since v4:
- Revert back to a single fallback bindind qcom,tsens-v2 as per Rob's
- Rework how old (unsplit SROT and TM address space) DTs are handled by
  needing a 0x1000 offset but still sharing common code in tsens-v2.c
- Remove the patch to added TRDY checks while we investigate Matthias'
- Fix unit addressses for the two tsens blocks as per Stephen's comment.

Changes since v3:
- Introduce qcom,tsens-v2.4.0 property and make qcom,tsens-v2 a
  fallback, compatible property.
- Rename ops_v2 to ops_generic_v2

Changes since v2:

- Based on review, moved tsens-8996.c to tsens-v2.c and changed
  corresponding function names, struct names to allow for generic tsensv2
- All v2 platforms will now only need to use the qcom,tsen-v2
- Added a DT patch to initialize tsens driver on sdm845, now that
  4.18-rc1 will contain an sdm845.dtsi

Changes since v1:
- Move get_temp() from tsens-8996 to tsens-common and rename
- Change 8996 DT entry to allow init_common() to work across
  sdm845 and 8996 due to different offsets

Amit Kucheria (7):
  thermal: tsens: Get rid of unused fields in structure
  thermal: tsens: Add support to split up register address space into
  arm64: dts: msm8996: thermal: Initialise via DT and add second
  thermal: tsens: Rename tsens-8996 to tsens-v2 for reuse
  dt: thermal: tsens: Document the fallback DT property for v2 of TSENS
  thermal: tsens: Add generic support for TSENS v2 IP
  arm64: dts: sdm845: Add tsens nodes
