Pull thermal management updates from Zhang Rui:

 - Add locking for cooling device sysfs attribute in case the cooling
   device state is changed by userspace and thermal framework
   simultaneously. (Thara Gopinath)

 - Fix a problem that passive cooling is reset improperly after system
   suspend/resume. (Wei Wang)

 - Cleanup the driver/thermal/ directory by moving intel and qcom
   platform specific drivers to platform specific sub-directories. (Amit
   Kucheria)

 - Some trivial cleanups. (Lukasz Luba, Wolfram Sang)

thermal: tsens: qcom: do not create duplicate regmap debugfs entries

2019-01-02T12:47:11+00:00

Regmap would use device name to create debugfs entries. If the device
has multiple regmaps it is recommended to use name field in regmap_config.
Fix this by providing name to the regmap configs correctly.

Without this patch we would see below error on DB820c.

drivers: thermal: Move QCOM_SPMI_TEMP_ALARM into the qcom subdir

2018-12-07T08:49:02+00:00

This cleans up the directory a bit allowing just one place to look for
thermal related drivers for QCOM platforms instead of being scattered in
the root directory and the qcom/ subdirectory. Compile-tested with
ARCH=arm64 defconfig and the driver explicitly enabled with menuconfig.

thermal: tsens: Check if the IP is correctly enabled by firmware

2018-10-23T00:35:30+00:00

The SROT registers are initialised by the secure firmware at boot. We
don't have write access to the registers. Check if the block is enabled
before continuing.

thermal: tsens: Pass register offsets as private data

2018-10-23T00:34:33+00:00

Registers have moved around across TSENS generations. For example, the
CTRL register was at offset 0x0 in the SROT region on msm8916 but is at
offset 0x4 in newer v2 based TSENS HW blocks.

Allow passing offsets of important registers so that we can continue to
use common functions.

thermal: tsens: Add the SROT address map

2018-10-23T00:33:48+00:00

On platforms whose device trees specify two address spaces for TSENS, the
second one points to the SROT registers. Initialise the SROT map on those
platforms.

thermal: tsens: Rename map field in order to add a second address map

2018-10-23T00:33:23+00:00

The TSENS driver currently only uses a limited set of registers from the TM
address space. So it was ok to map just that set of registers and call it
"map".

We'd now like to map a second set: SROT registers to introduce new
functionality. Rename the "map" field to a more appropriate "tm_map".

The 8960 doesn't have a clear split between TM and SROT registers. To avoid
complicating the data structure, it will switchover to using tm_map for its
maps.

There is no functional change with this patch.

thermal: tsens: Prepare 8916 and 8974 tsens to use SROT and TM address space

2018-10-23T00:31:15+00:00

We've already converted over the devicetree of platforms using v2
version of the TSENS IP to use two address spaces. Now prepare to
convert over the 8916 and 8974 platforms to use separate SROT and TM
address spaces.

This patch will work with device trees with one or two address spaces
because we set the tm_offset in commit 5b1283984fa3 ("thermal: tsens:
Add support to split up register address space into two").
