[PATCH v13 0/9] Add support for ipq8064 tsens

[PATCH v13 0/9] Add support for ipq8064 tsens

[Ansuel Smith]

This patchset convert msm8960 to reg_filed, use int_common instead 
of a custom function and fix wrong tsens get_temp function for msm8960.
Ipq8064 SoCs tsens driver is based on 8960 tsens driver. Ipq8064 needs
to be registered as a gcc child as the tsens regs on this platform are
shared with the controller.
This is based on work and code here
https://git.linaro.org/people/amit.kucheria/kernel.git/log/?h=wrk3/tsens-8960-breakage

v13:
* Simple reword
v12:
* Even more fix reported by Thara
v11:
* Address comments from Thara (thx)
v10:
* Fix wrong tsens init for ver_0 (crit_trips needs to be set in tsens_register)
v9:
* Fix warning from Documentation bot
v8:
* Drop MIN and MAX THRESH and use CRIT_THRESH instead
* Fix broken documentation patch
v7:
* Rework calibrate function to use get_temp_common
* Fix wrong required in the Documentation for ipq8064
* Fix hardware bug in sensor enable function
v6:
* Fix spelling error (can't find the problem with variable misallignment)
* Rework big if-else
* Remove extra comments
* Add description about different interrupts
v5:
* Conver driver to use reg_fiedl
* Use init_common 
* Drop custom set_trip and set_interrupt
* Use common set_trip and set_interrupt
* Fix bad get_temp function
* Add missing hardcoded slope
v4:
* Fix compilation error and warning reported by the bot
v3:
* Change driver to register as child instead of use phandle
v2:
* Fix dt-bindings problems

[PATCH v13 1/9] drivers: thermal: tsens: Add VER_0 tsens version

[Ansuel Smith]

VER_0 is used to describe device based on tsens version before v0.1.
These device are devices based on msm8960 for example apq8064 or
ipq806x.

we short cut the rest of the function and return success.  It's hard to

Hi Ansuel,

I would like to close up the two series which are pending for this

Thanks

Function compute_intercept_slope hardcode the sensor slope to
SLOPE_DEFAULT. Change this and use the default value only if a slope is
not defined. This is needed for tsens VER_0 that has a hardcoded slope
table.

problem with sensor enablement. Sensor id 6-11 can't be enabled
selectively and all of them must be enabled in one step.
