[PATCH v7 00/15] thermal: qcom: tsens: Add interrupt support

[Amit Kucheria <amit.kucheria@linaro.org>]

Daniel, only patch 15 needs to be changed in the tree being submitted
to linux-next. But here is the entire series for completeness.

Hi Thermal and MSM maintainers,

I believe this series is now ready to be merged. The DT bindings and driver
changes should go through the thermal tree and the changes to the DT files
themselves should go through the MSM tree. There is no hard ordering
dependency because we're adding a new property to the driver. It would help
to soak in linux-next for a few weeks to catch anything on kernelci.org.

1-4, 7, 14, 15 => thermal tree
5, 6, 8-13 => msm tree (already applied by Andy)

Regards,
Amit

Changes since v6:
- Stephen reported a warning that only shows up with gcc 9.x
  (https://lore.kernel.org/lkml/CAHLCerOkeOEEUgtJ=YgDKKXDiyFXHQ4LBdzg3-3VtKvpyceqFg@mail.gmail.com/). Include a patch to initialise the index variable to zero.

Changes since v5:
- Julia found a missing put_device() call in the success path of
  tsens_register() while baking in linux-next. A single line change to
  allow the error and success path to use the call to put_device(). Thanks
  Julia and LKP.

Changes since v4:
- Change to of-thermal core[1] to force interrupts w/o changing polling-delay DT
  parameter
- Corresponding changes to DT files to remove the hunks setting the values
  to 0
- Collected reviews and acks

Changes since v3:
- Fix up the YAML definitions based on Rob's review

Changes since v2:
- Addressed Stephen's review comment
- Moved the dt-bindings to yaml (This throws up some new warnings in various QCOM
devicetrees. I'll send out a separate series to fix them up)
- Collected reviews and acks
- Added the dt-bindings to MAINTAINERS

Changes since v1:
- Collected reviews and acks
- Addressed Stephen's review comments (hopefully I got them all).
- Completely removed critical interrupt infrastructure from this series.
  Will post that separately.
- Fixed a bug in sign-extension of temperature.
- Fixed DT bindings to use the name of the interrupt e.g. "uplow" and use
  platform_get_irq_byname().

Add interrupt support to TSENS. The first 6 patches are general fixes and
cleanups to the driver before interrupt support is introduced.
