Currently the only way of excluding certain tests from a collection is by
passing all the other tests explicitly via `--test`. Therefore, if the user
wants to skip a single test the resulting command line might be too big,
depending on the collection. Add an option `--skip` that takes care of
that.

cpupower currently installs a cpupower.service unit file into unitdir
unconditionally, regardless of whether systemd is used by the host.
Improve the installation procedure by making this systemd step optional:
a 'SYSTEMD' build parameter that defaults to 'true' and can be set to
'false' to disable the installation of systemd's unit file.
Since 'SYSTEMD' defaults to true, the current behavior is kept as the
default.

This patch series adds CANFD support to RZ/V2H(P), RZ/V2N, RZ/T2H and
RZ/N2H SoCs.
The CANFD controller on RZ/V2H(P) and RZ/V2N SoCs is similar to the one
on RZ/G3E SoC, while the CANFD controller on RZ/T2H and RZ/N2H SoCs is
similar to R-Car Gen 4 SoCs but with some differences in terms of
number of channels and AFLPN and CFTML bits.
The patch series includes:
- Specifying reset-names for RZ/G2L and RZ/G3E CANFD controllers.
- Documenting the CANFD controller on RZ/V2H(P) and RZ/V2N SoCs.
- Documenting the CANFD controller on RZ/T2H and RZ/N2H SoCs.

In sensor variants (such as ADXL380 and ADXL382) that support low-power
mode, the SAR signal path allows sampling acceleration data at lower rates;
more specifically, when the sensor operates in VLP mode, the sampling
frequency is 1 kHz.
To add support for the 1kHz sampling frequency value, modify the operating
mode selection logic to take into account the sampling frequency, and
configure the decimation filters only when applicable (i.e. when using a
sampling frequency that relies on the DSM signal path); in addition,
constrain the available sampling frequency values based on whether the
sensor is operating in low-power mode.

The ADXL380 driver assumes that acceleration samples are always retrieved
via the high-performance DSM signal path; as a result, the sampling
frequency value depends exclusively on the decimation filter settings in
the TRIG_CFG register.
In preparation for adding support for sampling frequency values that rely
on the low-power SAR signal path (on which the decimation filters are not
supported), use the (currently unused) 'odr' member of struct adxl380_state
to store the sampling frequency value, and when userspace requests the
current frequency value, retrieve it from the struct instead of calculating
it from the decimation filter settings.

Multiple DRM drivers use the pm_runtime_put() return value for printing
debug or even error messages and all of those messages are at least
somewhat misleading.
Returning an error code from pm_runtime_put() merely means that it has
not queued up a work item to check whether or not the device can be
suspended and there are many perfectly valid situations in which that
can happen, like after writing "on" to the devices' runtime PM "control"
attribute in sysfs for one example. It also happens when the kernel
has been configured with CONFIG_PM unset.
For this reason, modify all of those drivers to simply discard the
pm_runtime_put() return value which is what they should be doing.
This will facilitate a planned change of the pm_runtime_put() return
type to void in the future.

Also update the irq_chip_pm_put() kerneldoc comment to be more accurate.

Previously, the pcie-qcom driver probed first, deasserted PERST#, enabled
link training and scanned the bus. By the time the pwrctrl driver probe got
called, link training was already enabled by the controller driver.
Thus the pwrctrl drivers had to call the .assert_perst() callback, to
assert PERST#, power on the needed resources, and then call the
.assert_perst() callback to deassert PERST#.
Now since all pwrctrl drivers and this controller driver have been
converted to the new pwrctrl design where the pwrctrl drivers will first
power on the devices before this driver deasserts PERST# and scan the bus.
So there is no longer a need for .assert_perst() callback in this driver
and in DWC core driver. Hence, drop them.

Adopt pwrctrl APIs to create, power on/off, and destroy pwrctrl devices.
In qcom_pcie_host_init(), call pci_pwrctrl_create_devices() to create
devices, then pci_pwrctrl_power_on_devices() to power them on, both after
controller resource initialization. Once successful, deassert PERST# for
all devices.
In qcom_pcie_host_deinit(), call pci_pwrctrl_power_off_devices() after
asserting PERST#. Note that pci_pwrctrl_destroy_devices() is not called
here, as deinit is only invoked during system suspend where device
destruction is unnecessary. If the driver becomes removable in future,
pci_pwrctrl_destroy_devices() should be called in the remove() handler.
Remove the old pwrctrl framework code from the PCI core (including
devlinks) as the new APIs are now the sole consumer of pwrctrl
functionality. And also do not power on the pwrctrl drivers during probe()
as this is now handled by the APIs.

To fix bridge resource allocation issues when powering PCI bridges with the
pwrctrl driver, introduce APIs to explicitly power on and off all related
devices simultaneously.
Previously, the individual pwrctrl drivers powered on/off the PCI devices
autonomously, without any control from the controller drivers. But to
enforce ordering with respect to powering on the devices, these APIs will
power on/off all the devices at the same time.
The pci_pwrctrl_power_on_devices() API recursively scans the PCI child
nodes, makes sure that pwrctrl drivers are bound to devices, and calls
their power_on() callbacks. If any pwrctrl driver is not bound, it will
return -EPROBE_DEFER.
Similarly, pci_pwrctrl_power_off_devices() API powers off devices
recursively via their power_off() callbacks.
These APIs are expected to be called during the controller probe and
suspend/resume time to power on/off the devices. But before calling these
APIs, the pwrctrl devices should be created using the
pci_pwrctrl_{create/destroy}_devices() APIs.

Previously, the PCI core created pwrctrl devices during pci_scan_device()
on its own and then skipped enumeration of those devices, hoping the
pwrctrl driver would power them on and trigger a bus rescan.
This approach works for endpoint devices directly connected to Root Ports,
but it fails for PCIe switches acting as bus extenders. When the switch
requires pwrctrl support and the pwrctrl driver is not available during
the pwrctrl device creation, its enumeration will be skipped during the
initial PCI bus scan.
This premature scan leads the PCI core to allocate resources (bridge
windows, bus numbers) for the upstream bridge based on available downstream
buses at scan time. For non-hotplug capable bridges, PCI core typically
allocates resources based on the number of buses available during the
initial bus scan, which happens to be just one if the switch is not powered
on and enumerated at that time. When the switch gets enumerated later on,
it will fail due to the lack of upstream resources.
As a result, a PCIe switch powered on by the pwrctrl driver cannot be
reliably enumerated currently. Either the switch has to be enabled in the
bootloader or the switch pwrctrl driver has to be loaded during the pwrctrl
device creation time to work around these issues.
Introduce new APIs to explicitly create and destroy pwrctrl devices from
controller drivers by recursively scanning the PCI child nodes of the
controller. These APIs allow creating pwrctrl devices based on the original
criteria and are intended to be called during controller probe and removal.
These APIs, together with the upcoming APIs for power on/off will allow the
controller drivers to power on all the devices before starting the initial
bus scan, thereby solving the resource allocation issue.

The pwrctrl drivers still power on the resources on their own now. So there
