Current set of patches apply on 4.6-rc6. Fixes for the nvmem apis
are now posted [1] and queued in -next [2]
Patches [1-6] will need to be merged via thermal tree/Eduardo.
Patches [7-11] will need to go via qcom-msm tree/Andy.
Changes since v5:
* Minor review fixes from Eduardo
Changes since v4:
* dropped qcom,tsens-slopes binding, used coefficients instead
* dropped qcom,sensor-id binding
* Added support for msm8996 family
* Other minor review fixes from v4
Changes since v3:
* Dropped 'clk: qcom: create virtual child device for TSENS' which
is picked up by Stephen
* Updated GCC bindings with optional TSENS properties
Changes since v2:
* Minor review fixes from Stephen/Punit and rebase on 4.3-rc4
Changes since v1:
* Created virtual tsens device from gcc driver for 8960,
with DT having a single node for gcc and tsens
* Minor fixes with rebasing on 4.3-rc1
Changes since RFC:
* Added support for 8916 and 8084
* Based off the latest nvmem framework patches [1]
* Minor review fixes for comments mostly from Lina
This is an attempt to have a single TSENS driver for
the different versions of the TSENS IP that exist, on
different qcom msm/apq SoCs'
Support is added for msm8916, msm8960, msm8974 and msm8996 families.
A lot of the work is based of original code from Stephen Boyd
and Siddartha Mohanadoss. I have also picked some of what
Narendran Rajan did in his attempt to upstream the support
for 8960 family. I could not keep the original authorship on
any of the patches because I ended up moving the code around
quite a bit in an effort to have a single driver for the
various devices. I would be glad to change the authorship
for any of the patches if needed.

TSENS is Qualcomms' thermal temperature sensor device. It
supports reading temperatures from multiple thermal sensors
present on various QCOM SoCs.
Calibration data is generally read from a non-volatile memory
(eeprom) device.
Add a skeleton driver with all the necessary abstractions so
a variety of qcom device families which support TSENS can
add driver extensions.
Also add the required device tree bindings which can be used
to describe the TSENS device in DT.

Add support to calibrate sensors on 8916 family and also add common
functions to read temperature from sensors (This can be reused on
other SoCs having similar TSENS device)
The calibration data is read from eeprom using the generic nvmem
framework apis.
Based on the original code by Siddartha Mohanadoss and Stephen Boyd.

8960 family of SoCs have the TSENS device as part of GCC, hence
the driver probes the virtual child device created by GCC and
uses the parent to extract all DT properties and reuses the GCC
regmap.
Also GCC/TSENS are part of a domain thats not always ON.
Hence add .suspend and .resume hooks to save and restore some of
the inited register context.
Also 8960 family have some of the TSENS init sequence thats
required to be done by the HLOS driver (some later versions of TSENS
do not export these registers to non-secure world, and hence need
these initializations to be done by secure bootloaders)
8660 from the same family has just one sensor and hence some register
offset/layout differences which need special handling in the driver.
Based on the original code from Siddartha Mohanadoss, Stephen Boyd and
Narendran Rajan.

To: linux-arm-kernel
The TSENS controller in 8996 family of SoCs is capable of converting the
ADC code outputs to real temperature values (in decidegree Celsius).
It can also be programmed to provide raw ADC code, but the secure software
on 8996 programs it to provide real temperatures and also does the needed
calibrations.
We check the valid bit to ensure valid data is read by the AHB master.
And the spec recommends the below algorithm to read data 3 consecutive
times, which takes care of the worst case delay taken to propagate the
updated data to the register.

TSENS is part of GCC, hence add TSENS properties as part of GCC node.
Also add thermal zones and qfprom nodes.
Update GCC bindings doc to mention the possibility of optional TSENS
properties that can be part of GCC node.

These patches have been on the list for quite a while, and they
do not have any outstanding dependencies or comments to be
addressed. I would really hope to see these in for 4.8.
Let me know if there is something you want me to address before
you pull them in.

Would you be able to pull this driver in? I haven't heard back
anything from Eduardo despite multiple pings.
These patches (v6) have been on the list for a couple months now,
which address all issues/concerns that were raised by Eduardo
in his previous reviews.

You have passive trip points, but not cooling devices.
The cooling-maps property is mandatory, as you can see
in the documentation
(Documentation/devicetree/bindings/thermal/thermal.txt)
Please add it, for all your zones.

Applied patches 1-6. The DT patches lack the cooling map, on all of
them. In case you do not have a working cooling device in your
platform, at least add an empty map with a TODO flag.
After you fix the DT patch, you may add my

Thanks Eduardo. I will add empty maps in cases where
CPUfreq support is still missing.

Sorry for my late response as I took medical leave earlier this month
for a noise surgery and I'm just back to work.
I synced with Eduardo yesterday, he was also really busy recently, but
he will go through the pending patches soon.
So, for this patch set, I still prefer to let Eduardo to take it if he
has time, and I will take them if you still don't get feedback from
Eduardo after the merge window, does this sound okay for you?
