[PATCH v14 0/9] Add support for ipq8064 tsens

[PATCH v14 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

v14:
* Fix warning reported by Dan Carpenter
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 v14 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.

[PATCH v14 2/9] drivers: thermal: tsens: Don't hardcode sensor slope

[Ansuel Smith]

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.

[PATCH v14 5/9] drivers: thermal: tsens: Fix bug in sensor enable for msm8960

[Ansuel Smith]

Device based on tsens VER_0 contains a hardware bug that results in some
problem with sensor enablement. Sensor id 6-11 can't be enabled
selectively and all of them must be enabled in one step.

[PATCH v14 6/9] drivers: thermal: tsens: Replace custom 8960 apis with generic apis

[Ansuel Smith]

Rework calibrate function to use common function. Derive the offset from
a missing hardcoded slope table and the data from the nvmem calib
efuses.
Drop custom get_temp function and use generic api.

thermal/drivers/tsens: Replace custom 8960 apis with generic apis

Rework calibrate function to use common function. Derive the offset from
a missing hardcoded slope table and the data from the nvmem calib
efuses.
Drop custom get_temp function and use generic api.

thermal/drivers/tsens: Fix bug in sensor enable for msm8960

Device based on tsens VER_0 contains a hardware bug that results in some
problem with sensor enablement. Sensor id 6-11 can't be enabled
selectively and all of them must be enabled in one step.

thermal/drivers/tsens: Add VER_0 tsens version

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.

thermal/drivers/tsens: Don't hardcode sensor slope

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.
