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

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

make -C1 throws a warning for this. You have to make the table static. 
You can keep my Acked-by once it is fixed.
