to host
On the Mediatek Genio 510-EVK and 700-EVK boards, ssusb2 controller is
one but has two ports: one is routed to the M.2 slot, the other is on
the RPi header who does support full OTG.
Since Mediatek Genio 700-EVK USB support was added, dual role mode
property is set to otg for ssusb2. This config prevents the M.2
Wifi/Bluetooth module, present on those boards and exposing Bluetooth
as an USB device to be properly detected at startup as the default role
is device.
To keep the OTG functionality and make the M.2 module be detected at
the same time, add role-switch-default-mode property set to host and
also fix the polarity of GPIO associated to the USB connector, so the
ssusb2 controller role is properly set to host when the other port is
unused.

Some of the regulators in the MT6357 PMIC dtsi have compatible set to
regulator-fixed, even though they don't serve any purpose: all those
regulators are handled as a whole by the mt6357-regulator driver. In
fact this is the only dtsi in this family of chips where this is the
case: mt6359 and mt6358 don't have any such compatibles.
A side-effect caused by this is that the DT kselftest, which is supposed
to identify nodes with compatibles that can be probed, but haven't,
shows these nodes as failures.
Remove the useless compatibles to move the dtsi in line with the others
in its family and fix the DT kselftest failures.

By hardware, the first and second core of the video decoder IP
need the VDEC_SOC to be powered up in order to be able to be
accessed (both internally, by firmware, and externally, by the
kernel).
Similarly, for the video encoder IP, the second core needs the
first core to be powered up in order to be accessible.
Fix that by reparenting the VDEC1/2 power domains to be children
of VDEC0 (VDEC_SOC), and the VENC1 to be a child of VENC0.

Based on the comments in the MT8188 IOMMU binding header, the rdma0
device specifies the wrong IOMMU device for the IOMMU port it is
tied to:
This SoC have two MM IOMMU HWs, this is the connected information:
iommu-vdo: larb0/2/5/9/10/11A/11C/13/16B/17B/19/21
iommu-vpp: larb1/3/4/6/7/11B/12/14/15/16A/17A/23/27
rdma0's endpoint is M4U_PORT_L1_DISP_RDMA0 (on larb1), which should use
iommu-vpp, but it is currently tied to iommu-vdo.
Somehow this went undetected until recently in Linux v6.15-rc1 with some
IOMMU subsystem framework changes that caused the IOMMU to no longer
work. The IOMMU would fail to probe if any devices associated with it
could not be successfully attached. Prior to these changes, only the
end device would be left without an IOMMU attached.

Create "pct_idle" counter group, the sofware notion of residency
so it can now be singled out, independent of other counter groups.
Create "cpuidle" group, the cpuidle invocation counts.
Disable "cpuidle", by default.
Create "swidle" = "cpuidle" + "pct_idle".
Undocument "sysfs", the old name for "swidle", but keep it working
for backwards compatibilty.
Create "hwidle", all the HW idle counters
Modify "idle", enabled by default
"idle" = "hwidle" + "pct_idle" (and now excludes "cpuidle")

... and don't error out so hard on missing module descriptions.
Before commit 6c6c1fc09de3 ("modpost: require a MODULE_DESCRIPTION()")
we used to warn about missing module descriptions, but only when
building with extra warnigns (ie 'W=1').
After that commit the warning became an unconditional hard error.
And it turns out not all modules have been converted despite the claims
to the contrary. As reported by Damian Tometzki, the slub KUnit test
didn't have a module description, and apparently nobody ever really
noticed.
The reason nobody noticed seems to be that the slub KUnit tests get
disabled by SLUB_TINY, which also ends up disabling a lot of other code,
both in tests and in slub itself. And so anybody doing full build tests
didn't actually see this failre.
So let's disable SLUB_TINY for build-only tests, since it clearly ends
up limiting build coverage. Also turn the missing module descriptions
error back into a warning, but let's keep it around for non-'W=1'
builds.

Probe cpuidle "sysfs" residency and counts separately,
since soon we will make one disabled on, and the
other disabled off.
Clarify that some BIC (build-in-counters) are actually "groups".
since we're about to re-name some of those groups.
no functional change.

The CoreThr column displays total thermal throttling events
since boot time.
Change it to report events during the measurement interval.
This is more useful for showing a user the current conditions.
Total events since boot time are still available to the user via
/sys/devices/system/cpu/cpu*/thermal_throttle/*

On systems with >= 1024 cpus (in my case 1152), turbostat fails with the error output:
"turbostat: /sys/fs/cgroup/cpuset.cpus.effective: cpu str malformat 0-1151"
A similar error appears with the use of turbostat --cpu when the inputted cpu
range contains a cpu number >= 1024:
# turbostat -c 1100-1151
"--cpu 1100-1151" malformed
...
Both errors are caused by parse_cpu_str() reaching its limit of CPU_SUBSET_MAXCPUS.
It's a good idea to limit the maximum cpu number being parsed, but 1024 is too low.
For a small increase in compute and allocated memory, increasing CPU_SUBSET_MAXCPUS
brings support for parsing cpu numbers >= 1024.
Increase CPU_SUBSET_MAXCPUS to 8192, a common setting for CONFIG_NR_CPUS on x86_64.
