Currently, The imx pgc power domain doesn't set the fwnode
pointer, which results in supply regulator device can't get
consumer imx pgc power domain device from fwnode when creating
a link.
This causes the driver core to instead try to create a link
between the parent gpc device of imx pgc power domain device and
supply regulator device. However, at this point, the gpc device
has already been bound, and the link creation will fail. So adding
the fwnode pointer to the imx pgc power domain device will fix
this issue.

for the VDDCX and VDDMX power domains in voltage level mode,

The commit c494a447c14e ("soc: bcm: bcm2835-power: Refactor ASB control")
refactored the ASB control by using a general function to handle both
the enable and disable. But this patch introduced a subtle regression:
we need to check if !!(readl(base + reg) & ASB_ACK) == enable, not just
check if (readl(base + reg) & ASB_ACK) == true.
Currently, this is causing an invalid register state in V3D when
unloading and loading the driver, because `bcm2835_asb_disable()` will
return -ETIMEDOUT and `bcm2835_asb_power_off()` will fail to disable the
ASB slave for V3D.

This updates the power domain to support WAY_EN operations. WAY_EN
operations on mt8365 are using a different component to check for the
acknowledgment, namely the infracfg-nao component. Also to enable a way
it the bit needs to be cleared while disabling a way needs a bit to be
set. To support these two operations two flags are added,
BUS_PROT_INVERTED and BUS_PROT_STA_COMPONENT_INFRA_NAO. Additionally
another regmap is created if the INFRA_NAO capability is set.
This operation is required by the mt8365 for the MM power domain.

When building with clang 18 I see the following warning:
| drivers/soc/renesas/rmobile-sysc.c:193:22: warning: cast to smaller integer
| type 'enum pd_types' from 'const void *' [-Wvoid-pointer-to-enum-cast]
| 193 | add_special_pd(np, (enum pd_types)id->data);
This is due to the fact that `id->data` is a void* and `enum pd_types`
has the size of an integer. This cast from pointer-width to int-width
causes truncation and possible data loss. Instead, cast to `uintptr_t`
which has the same width as void*.

The DT of_device.h and of_platform.h date back to the separate
of_platform_bus_type before it as merged into the regular platform bus.
As part of that merge prepping Arm DT support 13 years ago, they
"temporarily" include each other. They also include platform_device.h
and of.h. As a result, there's a pretty much random mix of those include
files used throughout the tree. In order to detangle these headers and
replace the implicit includes with struct declarations, users need to
explicitly include the correct includes.

[Ulf: Re-based to fit the pmdomain subsystem]

It has been pointed out that naming a subsystem "genpd" isn't very
self-explanatory and the acronym itself that means Generic PM Domain, is
known only by a limited group of people.
In a way to improve the situation, let's rename the subsystem to pmdomain,
which ideally should indicate that this is about so called Power Domains or
"PM domains" as we often also use within the Linux Kernel terminology.

Pull drm ci scripts from Dave Airlie:
"This is a bunch of ci integration for the freedesktop gitlab instance
where we currently do upstream userspace testing on diverse sets of
GPU hardware. From my perspective I think it's an experiment worth
going with and seeing how the benefits/noise playout keeping these
files useful.
Ideally I'd like to get this so we can do pre-merge testing on PRs
eventually.
Below is some info from danvet on why we've ended up making the
decision and how we can roll it back if we decide it was a bad plan.
Why in upstream?
- like documentation, testcases, tools CI integration is one of these
things where you can waste endless amounts of time if you
accidentally have a version that doesn't match your source code
- but also like the above, there's a balance, this is the initial cut
of what we think makes sense to keep in sync vs out-of-tree,
probably needs adjustment
- gitlab supports out-of-repo gitlab integration and that's what's
been used for the kernel in drm, but it results in per-driver
fragmentation and lots of duplicated effort. the simple act of
smashing an arbitrary winner into a topic branch already started
surfacing patches on dri-devel and sparking good cross driver team
discussions
Why gitlab?
- it's not any more shit than any of the other CI
- drm userspace uses it extensively for everything in userspace, we
have a lot of people and experience with this, including
integration of hw testing labs
- media userspace like gstreamer is also on gitlab.fd.o, and there's
discussion to extend this to the media subsystem in some fashion
Can this be shared?
- there's definitely a pile of code that could move to scripts/ if
other subsystem adopt ci integration in upstream kernel git. other
bits are more drm/gpu specific like the igt-gpu-tests/tools
integration
- docker images can be run locally or in other CI runners
Will we regret this?
- it's all in one directory, intentionally, for easy deletion
- probably 1-2 years in upstream to see whether this is worth it or a
Big Mistake. that's roughly what it took to _really_ roll out solid
CI in the bigger userspace projects we have on gitlab.fd.o like
mesa3d"

Pull more RISC-V updates from Palmer Dabbelt:
- The kernel now dynamically probes for misaligned access speed, as
opposed to relying on a table of known implementations.
- Support for non-coherent devices on systems using the Andes AX45MP
core, including the RZ/Five SoCs.
- Support for the V extension in ptrace(), again.
- Support for KASLR.
- Support for the BPF prog pack allocator in RISC-V.
- A handful of bug fixes and cleanups.
