1c49e3783f selftests/memfd: Fix implicit declaration warnings
The memfd tests emit several warnings:

  fuse_test.c:261:7: warning: implicit declaration of function 'open'
  fuse_test.c:67:6: warning: implicit declaration of function 'fcntl'
  memfd_test.c:397:6: warning: implicit declaration of function 'fallocate'
  memfd_test.c:64:7: warning: implicit declaration of function 'open'
  memfd_test.c:90:6: warning: implicit declaration of function 'fcntl'

These are all caused by the test not including fcntl.h.

Instead of including linux/fcntl.h, include fcntl.h, which should
eventually cause the former to be included as well.

b68c1c65de selftests/gpio: Fix build when source tree is read only
Currently the gpio selftests fail to build if the source tree is read
only:

  make -j 160 -C tools/testing/selftests TARGETS=gpio
  make[1]: Entering directory '/linux/tools/testing/selftests/gpio'
  make OUTPUT=/linux/tools/gpio/ -C /linux/tools/gpio
  make[2]: Entering directory '/linux/tools/gpio'
  mkdir -p /linux/tools/gpio/include/linux 2>&1 || true
  ln -sf /linux/tools/gpio/../../include/uapi/linux/gpio.h /linux/tools/gpio/include/linux/gpio.h
  ln: failed to create symbolic link '/linux/tools/gpio/include/linux/gpio.h': Read-only file system

This happens because we ask make to build ../../../gpio (tools/gpio)
without pointing OUTPUT away from the source directory.

To fix it we create a subdirectory of the existing OUTPUT directory,
called tools-gpio, and tell tools/gpio to build in there.

Merge series "regulator: bd718x7: support voltage scaling" from Matti Vaittinen <matti.vaittinen@fi.rohmeurope.com>:
RFC for adding a support for typical voltage scaling connection

In few occasions there has been a need to scale the voltage output
from bucks on BD71837. Usually this is done when buck8 is used to
power specific GPU which can utilize voltages down to 0.7V. As lowest
the buck8 on BD71837 can go is 0.8V, and external connection is used to
scale the voltages.

The BD71837, BD71847 and BD71850 bucks can be adjusted by pulling up the
feedback pin using suitable voltage/resistors.

	|---------------|
	|       buck 8  |-------+----->Vout
	|               |       |
	|---------------|       |
	       |                |
	       |                |
	       +-------+--R2----+
	               |
	               R1
	               |
	       V FB-pull-up

This will scale the voltage as follows:
 - Vout_o = Vo - (Vpu - Vo)*R2/R1
 - Linear_step = step_orig*(R1+R2)/R1
where:
Vout_o is adjusted voltage output at vsel reg value 0
Vo is original voltage output at vsel reg value 0
Vpu is the pull-up voltage V FB-pull-up in the picture
R1 and R2 are resistor values.

>From HW point of view this does not need to be limited to buck 8. This
connection can be used to adjust output from any of the bucks on
BD71837/47/50.

As this seems to be a 'de-facto' way to scale the voltages on BD71837 it
might be a good idea to support computing the new voltage ranges for
bucks based on the V-pull-up and resistor R1/R2 values given from
device-tree. This allows describing the external HW connection using DT
to correctly scale the voltages.

This RFC uses "rohm,feedback-pull-up-r1-ohms" and
"rohm,feedback-pull-up-r2-ohms" to provide the resistor values - but
these names (without the picture) might not be too descriptive. I am
grateful for all suggestions as better and more descriptive names.

This patch series is an RFC because this connection feels somewhat
"hacky". OTOH - when hack becomes widely used, it is less of an hack and
more of a standard - and occasionally supporting HW hacks using SW may
benefit us all, right? :)

The other thing some projects do is allowing the change of BD71837 buck8
voltages when buck8 is enabled. This however will introduce voltage
spikes as buck8 was not originally designed for this. The specific HW
platform must be evaluated to be able to tolerate these spikes. Thus
this patch series does not support buck8 voltage changes when buck8 is
enabled. I wonder if this should be allowed per some config option(?) I
don't want to help people frying their boards... Opinions? Is there
suggested way of allowing this type of features at own risk? Config or
even Some #ifdef which is not listed in Kconfig? Device-tree property?
 If you have (good) suggestions I could add the optional (non default)
DVS support for non DVS bucks on BD71837.

Merge series "Audio Graph Updates" from Sameer Pujar <spujar@nvidia.com>:
This series is a prepraration for using generic graph driver for Tegra210
audio. Tegra audio graph series will be sent in a separate series because
it has some dependency over other series for documentation work. This
series can focus on the generic ASoC driver updates. Below are the summary
of changes done.

 * Support multiple instances of a component. For example there can be
   multiple I2S devices which can use the same component driver.

 * Support open platforms with empty Codec endpoint. Customers can plug
   their own HW and can populate codec endpoint.

 * In a component model there can be many components which can be
   connected together. In such cases Identify no-pcm DPCM DAI links which
   can be used in BE<->BE connections.

 * Expose structures or helpers to be re-used by other similar graph
   drivers.

The series is based on following references where DPCM usgae for Tegra
Audio and simple-card driver proposal were discussed.

 * https://lkml.org/lkml/2020/4/30/519 (DPCM for Tegra)
 * https://lkml.org/lkml/2020/6/27/4 (simple-card driver)

Changelog
=========

v4 -> v5
--------
 * No changes in the core/audio-graph driver patches which are
   part of the current series.
 * Dropped Tegra audio patches and doc patches. This will be
   sent separately once the doc depdendencies are resolved.

v3 -> v4
--------
 * Added new patches to convert graph.txt and audio-graph-card.txt
   to corresponding json-schema files. Later these references
   are used in Tegra audio graph schema.

 * AHUB component binding docs are updated to reflect the usage
   of ports/port/endpoint

 * More common stuff is moved into graph_parse_of() and this is
   used by both generic and Tegra audio graph.

 * DT binding for Tegra audio graph is updated to included "ports { }"

 * As per the suggestion 'void *data' member is dropped from
   'asoc_simple_priv' and instead container method is used to
   maintain required custom data internal to Tegra audio graph.

v2 -> v3
--------
 * Dropped new compatible addition in generic graph driver
   after reviewing it with Morimoto-san. Instead added Tegra
   audio graph driver and new compatibles are added in the same.
 * Added new patches to expose new members for customization
   in audio graph driver.
 * Added new patch for Tegra audio graph driver and related
   documentation.
 * Minor change in below commit where mutex version of helper is used
   "ASoC: audio-graph: Identify 'no_pcm' DAI links for DPCM"
 * DT binding is updated to use the newly exposed compatibles
 * No changes in other patches

v1 -> v2
--------
 * Re-organized ports/endpoints description for ADMAIF and XBAR.
   Updated DT patches accordingly.
 * After above change, multiple Codec endpoint support is not
   required and hence dropped for now. This will be considered
   separately if at all required in future.
 * Re-ordered patches in the series.

060352e141 kunit: tool: fix extra trailing \n in raw + parsed test output
For simplcity, strip all trailing whitespace from parsed output.
I imagine no one is printing out meaningful trailing whitespace via
KUNIT_FAIL() or similar, and that if they are, they really shouldn't.

`isolate_kunit_output()` yielded liens with trailing \n, which results
in artifacty output like this:

$ ./tools/testing/kunit/kunit.py run
[16:16:46] [FAILED] example_simple_test
[16:16:46]     # example_simple_test: EXPECTATION FAILED at lib/kunit/kunit-example-test.c:29

[16:16:46]     Expected 1 + 1 == 3, but

[16:16:46]         1 + 1 == 2

[16:16:46]         3 == 3

[16:16:46]     not ok 1 - example_simple_test

[16:16:46]

After this change:
[16:16:46]     # example_simple_test: EXPECTATION FAILED at lib/kunit/kunit-example-test.c:29
[16:16:46]     Expected 1 + 1 == 3, but
[16:16:46]         1 + 1 == 2
[16:16:46]         3 == 3
[16:16:46]     not ok 1 - example_simple_test
[16:16:46]

We should *not* be expecting lines to end with \n in kunit_tool_test.py
for this reason.

Do the same for `raw_output()` as well which suffers from the same
issue.

This is a followup to [1], but rebased onto kunit-fixes to pick up the
other raw_output() fix and fixes for kunit_tool_test.py.

390881448b kunit: tool: print out stderr from make (like build warnings)
Currently the tool redirects make stdout + stderr, and only shows them
if the make command fails.
This means build warnings aren't shown to the user.

This change prints the contents of stderr even if make succeeds, under
the assumption these are only build warnings or other messages the user
likely wants to see.

We drop stdout from the raised exception since we can no longer easily
collate stdout and stderr and just showing the stderr seems fine.

Example with a warning:

[14:56:35] Building KUnit Kernel ...
../lib/kunit/kunit-test.c: In function ‘kunit_test_successful_try’:
../lib/kunit/kunit-test.c:19:6: warning: unused variable ‘unused’ [-Wunused-variable]
   19 |  int unused;
      |      ^~~~~~

[14:56:40] Starting KUnit Kernel ...

Note the stderr has a trailing \n, and since we use print, we add
another, but it helps separate make and kunit.py output.

Example with a build error:

[15:02:45] Building KUnit Kernel ...
ERROR:root:../lib/kunit/kunit-test.c: In function ‘kunit_test_successful_try’:
../lib/kunit/kunit-test.c:19:2: error: unknown type name ‘invalid_type’

Only 8 bits are used to represent link rate at sinker DPCD.
The really link rate is 2.7Mb times the 8 bits value.
For example, 0x0A at DPCD is equal to 2.7Gb (10 * 2.7Mb).
This patch also convert 8 bits value of DPCD to really link

`kunit.py run` will not check and complain about invalid types at
runtime.

Fix pre-existing issues found by running a type checker
$ mypy *.py

All but one of these were returning `None` without denoting this
properly (via `Optional[Type]`).

3959d0a63b kunit: Fix kunit.py parse subcommand (use null build_dir)
When JSON support was added in [1], the KunitParseRequest tuple was
updated to contain a 'build_dir' field, but kunit.py parse doesn't
accept --build_dir as an option. The code nevertheless tried to access
it, resulting in this error:

AttributeError: 'Namespace' object has no attribute 'build_dir'

Given that the parser only uses the build_dir variable to set the
'build_environment' json field, we set it to None (which gives the JSON
'null') for now. Ultimately, we probably do want to be able to set this,
but since it's new functionality which (for the parse subcommand) never
worked, this is the quickest way of getting it back up and running.

41f71629b4 drm/tegra: replace idr_init() by idr_init_base()
idr_init() uses base 0 which is an invalid identifier for this driver.
The new function idr_init_base allows IDR to set the ID lookup from
base 1. This avoids all lookups that otherwise starts from 0 since
0 is always unused.

670c90def0 cpuidle: psci: Enable suspend-to-idle for PSCI OSI mode
To select domain idlestates for cpuidle-psci when OSI mode has been
enabled, the PM domains via genpd are being managed through runtime PM.
This works fine for the regular idlepath, but it doesn't during system wide
suspend. More precisely, the domain idlestates becomes temporarily
disabled, which is because the PM core disables runtime PM for devices
during system wide suspend.

Later in the system suspend phase, genpd intends to deal with this from its
->suspend_noirq() callback, but this doesn't work as expected for a device
corresponding to a CPU, because the domain idlestates needs to be selected
on a per CPU basis (the PM core doesn't invoke the callbacks like that).

To address this problem, let's enable the syscore flag for the
corresponding CPU device that becomes successfully attached to its PM
domain (applicable only in OSI mode). This informs the PM core to skip
invoke the system wide suspend/resume callbacks for the device, thus also
prevents genpd from screwing up its internal state of it.

Moreover, to properly select a domain idlestate for the CPUs during
suspend-to-idle, let's assign a specific ->enter_s2idle() callback for the
corresponding domain idlestate (applicable only in OSI mode). From that
callback, let's invoke dev_pm_genpd_suspend|resume(), as this allows a
domain idlestate to be selected for the current CPU by genpd.

b9795a3e4e PM: domains: Enable dev_pm_genpd_suspend|resume() for suspend-to-idle
The dev_pm_genpd_suspend|resume() have so far only been used during the
syscore suspend/resume phases. However, during suspend-to-idle, where the
syscore phases doesn't exist, similar operations are sometimes needed.

An existing example are the timekeeping_suspend|resume() functions, which
are being called both through a registered syscore ops during the syscore
phases, but also as regular functions calls from cpuidle (via
tick_freeze()) during suspend-to-idle.

For similar reasons, let's enable the dev_pm_genpd_suspend|resume() APIs to
be re-used for corresponding CPU devices that are attached to a genpd,
during suspend-to-idle.

5a64f77569 PM: EM: Clarify abstract scale usage for power values in Energy Model
The Energy Model (EM) can store power values in milli-Watts or in abstract
scale. This might cause issues in the subsystems which use the EM for
estimating the device power, such as:

 - mixing of different scales in a subsystem which uses multiple
   (cooling) devices (e.g. thermal Intelligent Power Allocation (IPA))

 - assuming that energy [milli-Joules] can be derived from the EM power
   values which might not be possible since the power scale doesn't have
   to be in milli-Watts

To avoid misconfiguration add the requisite documentation to the EM and
related subsystems: EAS and IPA.
