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.

This series has been developed against qcs404 and sdm845 and then tested on
msm8916 and msm8974 (Thanks Brian). Testing on msm8998 would be appreciated since I don't
have hardware handy.

There are two fields - id and hw_id - to track what sensor an action was
to performed on. This was because the sensors connected to a TSENS IP
might not be contiguous i.e. 1, 2, 4, 5 with 3 being skipped.

This causes confusion in the code which uses hw_id sometimes and id
other times (tsens_get_temp, tsens_get_trend).

Switch to only using the hw_id field to track the physical ID of the
sensor. When we iterate through all the sensors connected to an IP
block, we use an index i to loop through the list of sensors, and then
return the actual hw_id that is registered on that index.

-* QCOM SoC Temperature Sensor (TSENS)
-
-Required properties:
-- compatible:
-  Must be one of the following:
-    - "qcom,msm8916-tsens" (MSM8916)
-    - "qcom,msm8974-tsens" (MSM8974)
-    - "qcom,msm8996-tsens" (MSM8996)

-    - "qcom,msm8998-tsens", "qcom,tsens-v2" (MSM8998)
-    - "qcom,sdm845-tsens", "qcom,tsens-v2" (SDM845)
-  The generic "qcom,tsens-v2" property must be used as a fallback for any SoC
-  with version 2 of the TSENS IP. MSM8996 is the only exception because the
-  generic property did not exist when support was added.
-  Similarly, the generic "qcom,tsens-v1" property must be used as a fallback for
-  any SoC with version 1 of the TSENS IP.
-
-- reg: Address range of the thermal registers.
-  New platforms containing v2.x.y of the TSENS IP must specify the SROT and TM
-  register spaces separately, with order being TM before SROT.
-  See Example 2, below.
-
-- #thermal-sensor-cells : Should be 1. See ./thermal.txt for a description.
-- #qcom,sensors: Number of sensors in tsens block
-- Refer to Documentation/devicetree/bindings/nvmem/nvmem.txt to know how to specify
-nvmem cells
-

-		reg = <0x4a8000 0x2000>;
-		nvmem-cells = <&tsens_caldata>, <&tsens_calsel>;
-		nvmem-cell-names = "caldata", "calsel";
-		#thermal-sensor-cells = <1>;
-	};

-Example 2 (for any platform containing v2 of the TSENS IP):
-tsens0: thermal-sensor@c263000 {
-		compatible = "qcom,sdm845-tsens", "qcom,tsens-v2";
-		reg = <0xc263000 0x1ff>, /* TM */
-			<0xc222000 0x1ff>; /* SROT */
-		#qcom,sensors = <13>;
-		#thermal-sensor-cells = <1>;

-Example 3 (for any platform containing v1 of the TSENS IP):

Depending on the IP version, TSENS supports upper, lower and critical
threshold interrupts. We only add support for upper and lower threshold
interrupts for now.

TSENSv2 has an irq [status|clear|mask] bit tuple for each sensor while
earlier versions only have a single bit per sensor to denote status and
clear. These differences are handled transparently by the interrupt
handler. At each interrupt, we reprogram the new upper and lower threshold
in the .set_trip callback.
