Srinivas Pandruvada 4cba7d2363 thermal: intel_pch_thermal: Enable Skylake PCH thermal
Enabled temperature reporting device of Skylake Platform Controller hub.
The register map is same as the wildcat point thermal currently implemented
in this driver.

Julia Lawall a96bedf1b8 thermal: constify pch_dev_ops structure
The pch_dev_ops structure is never modified.  It is only stored in a field
that is already declared as const.

Done with the help of Coccinelle.

Linus Torvalds dfb22fc5c0 thermal: fix intel PCH thermal driver mismerge
I didn't notice this when merging the thermal code from Zhang, but his
merge (commit 5a924a07f882: "Merge branches 'thermal-core' and
'thermal-intel' of .git into next") of the thermal-core and
thermal-intel branches was wrong.

In thermal-core, commit 17e8351a77 ("thermal: consistently use int for
temperatures") converted the thermal layer to use "int" for
temperatures.

But in parallel, in the thermal-intel branch commit d0a12625d2
("thermal: Add Intel PCH thermal driver") added support for the intel
PCH thermal sensor using the old interfaces that used "unsigned long"
pointers.

This resulted in warnings like this:

  drivers/thermal/intel_pch_thermal.c:184:14: warning: initialization from incompatible pointer type [-Wincompatible-pointer-types]
    .get_temp = pch_thermal_get_temp,
                ^
  drivers/thermal/intel_pch_thermal.c:184:14: note: (near initialization for ‘tzd_ops.get_temp’)
  drivers/thermal/intel_pch_thermal.c:186:19: warning: initialization from incompatible pointer type [-Wincompatible-pointer-types]
    .get_trip_temp = pch_get_trip_temp,
                     ^
  drivers/thermal/intel_pch_thermal.c:186:19: note: (near initialization for ‘tzd_ops.get_trip_temp’)

This fixes it.

Tushar Dave d0a12625d2 thermal: Add Intel PCH thermal driver
This change adds a thermal driver for Wildcat Point platform controller
hub. This driver register PCH thermal sensor as a thermal zone and
associate critical and hot trips if present.
