Because some newer hardware variants have multiple possible parents for
the RTC's timekeeping clock, this driver models it as a "rtc-32k" clock.
However, it does not add any consumer for this clock. This causes the
common clock framework to disable it, preventing RTC time access.
Since the RTC's timekeeping clock should always be enabled, regardless
of which drivers are loaded, let's mark this clock as critical instead
of adding a consumer in the RTC driver.

Currently the mpfs clock driver uses a reference clock called the
"msspll", set in the device tree, as the parent for the cpu/axi/ahb
(config) clocks. The frequency of the msspll is determined by the FPGA
bitstream & the bootloader configures the clock to match the bitstream.
The real reference is provided by a 100 or 125 MHz off chip oscillator.
However, the msspll clock is not actually the parent of all clocks on
the system - the reference clock for the rtc/mtimer actually has the
off chip oscillator as its parent.
In order to fix this, add support for reading the configuration of the
msspll & reparent the "config" clocks so that they are derived from
this clock rather than the reference in the device tree.

Since the commit 948fb0969e ("clk: Always clamp the rounded rate"),
the clk_core_determine_round_nolock() would clamp the requested rate
between min and max rates from the rate request. Normally these fields
would be filled by clk_core_get_boundaries() called from
clk_round_rate().
However clk_gfx3d_determine_rate() uses a manually crafted rate request,
which did not have these fields filled. Thus the requested frequency
would be clamped to 0, resulting in weird frequencies being requested
from the hardware.
Fix this by filling min_rate and max_rate to the values valid for the
respective PLLs (0 and ULONG_MAX).

clk_set_rate_range() works so that the frequency is re-evaulated each time the
rate is changed. Previously we wouldn't let clk providers see a rate that was
different if it was still within the range, which could be bad for power if the
clk could run slower when a range expands. Now the clk provider can decide to
do something differently when the constraints change. This broke Nvidia's clk
driver so we had to wait for the fix for that to bake a little more in -next.
The rate range patch series also introduced a kunit suite for the clk framework
that we're going to extend in the next release. It already made it easy to find
corner cases in the rate range patches so I'm excited to see it cover more clk
code and increase our confidence in core framework patches in the future. I
also added a kunit test for the basic clk gate code and that work will continue
to cover more basic clk types: muxes, dividers, etc.
Beyond the core code we have the usual set of clk driver updates and additions.
Qualcomm again dominates the diffstat here with lots more SoCs being supported
and i.MX follows afer that with a similar number of SoCs gaining clk drivers.
Beyond those large additions there's drivers being modernized to use
clk_parent_data so we can move away from global string names for all the clks
in an SoC. Finally there's lots of little fixes all over the clk drivers for

Here is the big set of staging driver updates for 5.18-rc1.
Loads of tiny cleanups for almost all staging drivers in here, nothing
major at all. Highlights include:
- remove the ashmem Android driver. It is long-dead and if
there are any legacy userspace applications still using it,
the Android kernel images will maintain it, the community
shouldn't care about it anymore
- wfx wifi driver major cleanups. Should be ready to merge out
of staging soon, and will coordinate with the wifi maintainers
after -rc1 is out
- major cleanups and unwinding of the layers of the r8188eu
driver. It's amazing just how many unneeded layers of
abstraction is in there, just when we think it's done, another
is found...
- lots of tiny coding style cleanups in many other staging
drivers.
There will be merge conflict with a fbtft change and the spi driver
changes in your tree, but it's pretty obvious what to do (the function
shouldn't return anything.)
All have been in linux-next for a while with no reported problems.

When clk_put() is called we don't make another clk_set_rate() call to
re-evaluate the rate boundaries. This is unlike clk_set_rate_range()
that evaluates the rate again each time it is called.
However, clk_put() is essentially equivalent to clk_set_rate_range()
since after clk_put() completes the consumer's boundaries shouldn't be
enforced anymore.
Let's add a call to clk_set_rate_range() in clk_put() to make sure those
rate boundaries are dropped and the clock provider drivers can react.
Also add a few tests to make sure this case is covered.

A bug recently affected the Tegra30 where calling clk_set_rate_range()
on a clock would make it change its rate to the minimum.
This was due to the clock in question being a mux that was orphan at
registration, which lead to the clk_core req_rate being 0, and the
clk_set_rate_range() function then calling clk_set_rate() with req_rate,
effectively making that clock running at the minimum rate allowed, even
though the initial rate was within that range.
Make a test suite to create a mux initially orphan, and then make sure
that if our clock rate was initially within a given range, then
enforcing that range won't affect it.

When registering a clock that doesn't have a recalc_rate implementation,
and doesn't have its parent registered yet, we initialize the clk_core
rate and 'req_rate' fields to 0.
The rate field is later updated when the parent is registered in
clk_core_reparent_orphans_nolock() using __clk_recalc_rates(), but the
'req_rate' field is never updated.
This leads to an issue in clk_set_rate_range() and clk_put(), since
those functions will call clk_set_rate() with the content of 'req_rate'
to provide drivers with the opportunity to change the rate based on the
new boundaries. In this case, we would call clk_set_rate() with a rate
of 0, effectively enforcing the minimum allowed for this clock whenever
we would call one of those two functions, even though the actual rate
might be within range.
Let's fix this by setting 'req_rate' in
clk_core_reparent_orphans_nolock() with the rate field content just
updated by the call to __clk_recalc_rates().

The RTC power domain in sun6i and newer SoCs manages the 16 MHz RC
oscillator (called "IOSC" or "osc16M") and the optional 32 kHz crystal
oscillator (called "LOSC" or "osc32k"). Starting with the H6, this power
domain also handles the 24 MHz DCXO (called variously "HOSC", "dcxo24M",
or "osc24M") as well. The H6 also adds a calibration circuit for IOSC.
Later SoCs introduce further variations on the design:
- H616 adds an additional mux for the 32 kHz fanout source.
- R329 adds an additional mux for the RTC timekeeping clock, a clock
for the SPI bus between power domains inside the RTC, and removes the
IOSC calibration functionality.
Take advantage of the CCU framework to handle this increased complexity.
This driver is intended to be a drop-in replacement for the existing RTC
clock provider. So some runtime adjustment of the clock parents is
needed, both to handle hardware differences, and to support the old
binding which omitted some of the input clocks.

Since so far the key value is always the same, it does not need to be

Improve PRCI driver to reduce the complexity, we remove the SoCs C files
by putting all stuff in each SoCs header files, and include these
SoCs-specific header files in core of PRCI. It can also avoid the W=1
kernel build warnings about variable defined but not used
[-Wunused-const-variable=], like commit 487dc7bb6a ("clk: sifive:
fu540-prci: Declare static const variable 'prci_clk_fu540' where it's
used") does.

This patch is prerequisite for moving SoCs C files into SoCs header
files. Currently, fu540-prci.c and fu740-prci.c use same names for
several macro definitions and variables, it would cause redefinition
error when we trying to include all stuff in sifive-prci.c. In this
patch, we also remove the temporary macro definitions which are
added by previous patch.

This is a temporary patch in whole patch set. We are going to change the
macro name in dt-binding, in order to avoid breaking the driver build
and git bisect, add these macro definitions for the time being, and we
will remove them later.

Most of the i.MX clock generic API is built by selecting MXC_CLK.
Without it, the i.MX93 clock driver will fail to build:
aarch64-linux-gnu-ld: drivers/clk/imx/clk-imx93.o:
in function `imx93_clocks_probe': clk-imx93.c:(.text+0xa8):
undefined reference to `imx_obtain_fixed_clk_hw'
So fix this by selecting MXC_CLK for the CLK_IMX93.
Fixes: 24defbe194 ("clk: imx: add i.MX93 clk")

We no longer have users for the compatibility clocks and we can drop them.
These are old duplicate clocks for what we using.
