Here is the "big" driver core and debugfs changes for 5.3-rc1
It's a lot of different patches, all across the tree due to some api
changes and lots of debugfs cleanups. Because of this, there is going
to be some merge issues with your tree at the moment, I'll follow up
with the expected resolutions to make it easier for you.
Other than the debugfs cleanups, in this set of changes we have:
- bus iteration function cleanups (will cause build warnings
with s390 and coresight drivers in your tree)
- scripts/get_abi.pl tool to display and parse Documentation/ABI
entries in a simple way
- cleanups to Documenatation/ABI/ entries to make them parse
easier due to typos and other minor things
- default_attrs use for some ktype users
- driver model documentation file conversions to .rst
- compressed firmware file loading
- deferred probe fixes
All of these have been in linux-next for a while, with a bunch of merge
issues that Stephen has been patient with me for. Other than the merge
issues, functionality is working properly in linux-next :)

Now that the governor table is in place and the macro allows to browse the
table, declare the governor so the entry is added in the governor table
in the init section.
The [un]register_thermal_governors function does no longer need to use the
exported [un]register thermal governor's specific function which in turn
call the [un]register_thermal_governor. The governors are fully
self-encapsulated.
The cyclic dependency is no longer needed, remove it.

Currently the governors are declared in their respective files but they
export their [un]register functions which in turn call the [un]register
governors core's functions. That implies a cyclic dependency which is
not desirable. There is a way to self-encapsulate the governors by letting
them to declare themselves in a __init section table.
Define the table in the asm generic linker description like the other
tables and provide the specific macros to deal with.

When calling debugfs functions, there is no need to ever check the
return value. The function can work or not, but the code logic should
never do something different based on this.

There seems to be no good reason for omitting the CPU load information
depending on another tracepoint. My guess is that the intention was to
check whether thermal_power_cpu_get_power is (still) enabled, however
'load_cpu != NULL' already indicates that it was at least enabled when
cpufreq_get_requested_power() was entered, there seems little gain
from omitting the assignment if the tracepoint was just disabled, so
just remove the check.

Explicitly use the pinctrl to set/unset the right mode
instead of relying on the pinctrl init mode.
And it requires setting the tshut polarity before select pinctrl.
When the temperature sensor mode is set to 0, it will automatically
reset the board via the Clock-Reset-Unit (CRU) if the over temperature
threshold is reached. However, when the pinctrl initializes, it does a
transition to "otp_out" which may lead the SoC restart all the time.
"otp_out" IO may be connected to the RESET circuit on the hardware.
If the IO is in the wrong state, it will trigger RESET.
(similar to the effect of pressing the RESET button)
which will cause the soc to restart all the time.

Because IRQF_ONESHOT type interrupt line is kept disabled until
the threaded handler has been run, so there is no need to protect

thermal_of_cooling_device_register() and thermal_cooling_device_register()

thermal_cooling_device_unregister() is called from remove functions. This
makes both a perfect candidate for device managed functions.
Introduce devm_thermal_of_cooling_device_register(). This function can
also be used to replace thermal_cooling_device_register() by passing a NULL
pointer as device node. The new function requires both struct device *
and struct device_node * as parameters since the struct device_node *
parameter is not always identical to dev->of_node.

The module support for the thermal subsystem makes little sense:
- some subsystems relying on it are not modules, thus forcing the
framework to be compiled in
- it is compiled in for almost every configs, the remaining ones
are a few platforms where I don't see why we can not switch the thermal
to 'y'. The drivers can stay in tristate.
- platforms need the thermal to be ready as soon as possible at boot time
in order to mitigate
Usually the subsystems framework are compiled-in and the plugs are as
module.

The CPU cooling driver (cpu_cooling.c) allows the platform's cpufreq
driver to register as a cooling device and cool down the platform by
throttling the CPU frequency. In order to be able to auto-register a
cpufreq driver as a cooling device from the cpufreq core, we need access
to code inside cpu_cooling.c which, in turn, accesses code inside
thermal core.
CPU_FREQ is a bool while THERMAL is tristate. In some configurations
(e.g. allmodconfig), CONFIG_THERMAL ends up as a module while
CONFIG_CPU_FREQ is compiled in. This leads to following error:
drivers/cpufreq/cpufreq.o: In function `cpufreq_offline':
cpufreq.c:(.text+0x407c): undefined reference to `cpufreq_cooling_unregister'
drivers/cpufreq/cpufreq.o: In function `cpufreq_online':
cpufreq.c:(.text+0x70c0): undefined reference to `of_cpufreq_cooling_register'
Given that platforms using CPU_THERMAL usually want it compiled-in so it
is available early in boot, make CPU_THERMAL depend on THERMAL being
compiled-in instead of allowing it to be a module.
As a result of this change, get rid of the ugly (!CPU_THERMAL ||
THERMAL) dependency in all cpufreq drivers using CPU_THERMAL.

Changes since V1:
* Use dev_info instead of printk
* Use dev_warn instead of BUG_ON
Previously, sysfs_create_group was called before all initialization had
fully run - specifically, before pci_set_drvdata was called. Since the
sysctl group is visible to userspace as soon as sysfs_create_group
returns, a small window of time existed during which a process could read
from an uninitialized/partially-initialized device.
This commit moves the creation of the sysctl group to after all
initialized is completed. This ensures that it's impossible for
userspace to read from a sysctl file before initialization has fully
completed.
To catch any future regressions, I've added a check to ensure
that proc_thermal_emum_mode is never PROC_THERMAL_NONE when a process
tries to read from a sysctl file. Previously, the aforementioned race
condition could result in the 'else' branch
running while PROC_THERMAL_NONE was set,
leading to a null pointer deference.

The IP can manage to trigger interrupts on overheat situation from all
the sensors.
However, the interrupt source changes along with the last selected
source (ie. the last read sensor), which is an inconsistent behavior.
Avoid possible glitches by always selecting back only one channel which
will then be referenced as the "overheat_sensor" (arbitrarily: the first
in the DT which has a critical trip point filled in).
It is possible that the scan of all thermal zone nodes did not bring a
critical trip point from which the overheat interrupt could be
configured. In this case just complain but do not fail the probe.
Also disable sensor switch during overheat situations because changing
the channel while the system is too hot could clear the overheat state
by changing the source while the temperature is still very high.
Even if the overheat state is not declared, overheat interrupt must be
cleared by reading the DFX interrupt cause _after_ the temperature has
fallen down to the low threshold, otherwise future possible interrupts
would not be served. A work polls the corresponding register until the
overheat flag gets cleared in this case.

Merge tag 'kconfig-v4.21' of git://git.kernel.org/pub/scm/linux/kernel/git/masahiroy/linux-kbuild
Pull Kconfig updates from Masahiro Yamada:
- support -y option for merge_config.sh to avoid downgrading =y to =m
- remove S_OTHER symbol type, and touch include/config/*.h files correctly
- fix file name and line number in lexer warnings
- fix memory leak when EOF is encountered in quotation
- resolve all shift/reduce conflicts of the parser
- warn no new line at end of file
- make 'source' statement more strict to take only string literal
- rewrite the lexer and remove the keyword lookup table
- convert to SPDX License Identifier
- compile C files independently instead of including them from zconf.y
- fix various warnings of gconfig
- misc cleanups
* tag 'kconfig-v4.21' of git://git.kernel.org/pub/scm/linux/kernel/git/masahiroy/linux-kbuild: (39 commits)
kconfig: surround dbg_sym_flags with #ifdef DEBUG to fix gconf warning
kconfig: split images.c out of qconf.cc/gconf.c to fix gconf warnings
kconfig: add static qualifiers to fix gconf warnings
kconfig: split the lexer out of zconf.y
kconfig: split some C files out of zconf.y
kconfig: convert to SPDX License Identifier
kconfig: remove keyword lookup table entirely
kconfig: update current_pos in the second lexer
kconfig: switch to ASSIGN_VAL state in the second lexer
kconfig: stop associating kconf_id with yylval
kconfig: refactor end token rules
kconfig: stop supporting '.' and '/' in unquoted words
treewide: surround Kconfig file paths with double quotes
microblaze: surround string default in Kconfig with double quotes
kconfig: use T_WORD instead of T_VARIABLE for variables
kconfig: use specific tokens instead of T_ASSIGN for assignments
kconfig: refactor scanning and parsing "option" properties
kconfig: use distinct tokens for type and default properties
kconfig: remove redundant token defines
kconfig: rename depends_list to comment_option_list
...
The Kconfig lexer supports special characters such as '.' and '/' in
the parameter context. In my understanding, the reason is just to
support bare file paths in the source statement.
I do not see a good reason to complicate Kconfig for the room of
ambiguity.
The majority of code already surrounds file paths with double quotes,
and it makes sense since file paths are constant string literals.
Make it treewide consistent now.
