The clock framework handles clock rates as "unsigned long", so u32 on
32-bit architectures and u64 on 64-bit architectures.

The current code casts the dividend to u64 on 32-bit to avoid a
potential overflow. For example DIV_ROUND_UP(3000000000, 1500000000)
= (3.0G + 1.5G - 1) / 1.5G = = OVERFLOW / 1.5G, which has been
introduced in commit 9556f9da ("clk: divider: handle integer overflow
when dividing large clock rates").

On 64 bit platforms this masks the divisor, so that only the lower
32 bit are used. Thus requesting a frequency >= 4.3GHz results
in incorrect values. For example requesting 4300000000 (4.3 GHz) will
effectively request ca. 5 MHz. Requesting clk_round_rate(clk, ULONG_MAX)
is a bit of a special case, since that still returns correct values as
long as the parent clock is below 8.5 GHz.

Fix this by switching to DIV_ROUND_UP_NO_OVERFLOW, which cannot
overflow. This avoids any requirements on the arguments (except
that divisor should not be 0 obviously).

Add hardware description for the USB-C port in the Radxa Rock 5 Model B.
This describes the OHCI, EHCI and XHCI USB parts, but not yet the
DisplayPort AltMode (bindings are not yet upstream).

For now the fusb302 node is marked with status "fail", since the board
is usually powered through the USB-C port. Handling of errors can result
in hard resets, which removed the bus power for some time resulting in
a board reset.

The main problem right now is that devices are supposed to interact with
the power-supply within 5 seconds after the plug event according to the
USB PD specification. This is more or less impossible to achieve when
the kernel is the first software communicating with the power-supply.

Currently the most likely workaround will be USB-PD handling added to
U-Boot. In that case U-Boot can update the status to "okay". That way
booting a kernel with the updated DT on an old U-Boot avoids a reset
loop.

Enabling the GPU power domain requires that the GPU regulator is
enabled. The regulator is enabled at boot time, but automatically
gets disabled when there are no users.

If the GPU driver is not probed at boot time or rebound while
the system is running the system will try to enable the power
domain before the regulator is enabled resulting in a failure
hanging the whole system. Avoid this by adding an explicit
dependency.

Some power domains require extra voltages to be applied. For example
trying to enable the GPU power domain on RK3588 fails when the SoC
does not have VDD GPU enabled. The same is expected to happen for
the NPU, which also has a dedicated supply line.

We get the regulator using devm_of_regulator_get(), so a missing
dependency in the devicetree is handled gracefully by printing a warning
and creating a dummy regulator. This is necessary, since existing DTs do
not have the regulator described. They might still work if the regulator
is marked as always-on. It is also working if the regulator is enabled
at boot time and the GPU driver is probed before the kernel disables
unused regulators.

The regulator itself is not acquired at driver probe time, since that
creates an unsolvable circular dependency. The power domain driver must
be probed early, since SoC peripherals need it. Regulators on the other
hand depend on SoC peripherals like SPI, I2C or GPIO. MediaTek does not
run into this, since they have two power domain drivers.

Add optional support for a voltage supply required to enable a
power domain. The binding follows the way it is handled by the
Mediatek binding to keep things consistent.

This will initially be used by the RK3588 GPU power domain, which
fails to be enabled when the GPU regulator is not enabled. It is
not limited to that platform, since older generations have similar
requirements. They worked around this by marking the regulators
as always-on instead of describing the dependency.

The Rockchip power-domain controller also plans to make use of
per-domain regulators similar to the MediaTek power-domain controller.
Since existing DTs are missing the regulator information, the kernel
should fallback to the automatically created dummy regulator if
necessary. Thus the version without the _optional suffix is needed.

The Rockchip driver plans to use the managed version, but to be
consistent with existing code the unmanaged version is added at the
same time.

This reverts commit cc77e2ce.

It was reported that adding ATA_QUIRK_NOLPM for Samsung SSD 870 QVO drives
breaks entering lower package states for certain systems.

It turns out that Samsung SSD 870 QVO actually has working LPM when using
a recent SSD firmware version.

The author of commit cc77e2ce ("ata: libata-core: Add ATA_QUIRK_NOLPM
for Samsung SSD 870 QVO drives") reported himself that only older SSD
firmware versions have broken LPM:
https://lore.kernel.org/stable/93c10d38-718c-459d-84a5-4d87680b4da7@debian.org/



Unfortunately, he did not specify which older firmware version he was using
which had broken LPM.

Let's revert this quirk, which has FW version field specified as NULL
(which means that it applies for all Samsung SSD 870 QVO firmware versions)
for now. Once the author reports which older firmware version(s) that are
broken, we can create a more fine grained quirk, which populates the FW
version field accordingly.

A VMM may send a non-fatal signal to its threads, including vCPU tasks,
at any time, and thus may signal vCPU tasks during KVM_RUN.  If a vCPU
task receives the signal while its trying to spawn the huge page recovery
vhost task, then KVM_RUN will fail due to copy_process() returning
-ERESTARTNOINTR.

Rework call_once() to mark the call complete if and only if the called
function succeeds, and plumb the function's true error code back to the
call_once() invoker.  This provides userspace with the correct, non-fatal
error code so that the VMM doesn't terminate the VM on -ENOMEM, and allows
