clocksource/drivers: Add EcoNet Timer HPT driver

Introduce a clocksource driver for the so-called high-precision timer (HPT)
in the EcoNet EN751221 and EN751627 MIPS SoCs.

It's a 32 bit upward-counting one-shot timer which relies on the crystal so it
is unaffected by CPU power mode. On MIPS 34K devices (single core) there is
one timer, and on 1004K devices (dual core) there are two.

Each timer has two sets of count/compare registers so that there is one for
each of the VPEs on the core. Because each core has 2 VPEs, register selection
takes the CPU number / 2 for the timer corrisponding to the core, then CPU
number % 2 for the register corrisponding to the VPE.

These timers use a percpu-devid IRQ to route interrupts to the VPE which set
the event.

clocksource/drivers/nxp-timer: Add the System Timer Module for the s32gx platforms

STM supports commonly required system and application software timing
functions. STM includes a 32-bit count-up timer and four 32-bit
compare channels with a separate interrupt source for each
channel. The timer is driven by the STM module clock divided by an
8-bit prescale value (1 to 256).

STM has the following features:
• One 32-bit count-up timer with an 8-bit prescaler
• Four 32-bit compare channels
• An independent interrupt source for each channel
• Ability to stop the timer in Debug mode

The s32g platform is declined into two versions, the s32g2 and the
s32g3. The former has a STM block with 8 timers and the latter has 12
timers.

The platform is designed to have one usable STM instance per core on
the system which is composed of 3 x Cortex-M3 + 4 Cortex-A53 for the
s32g2 and 3 x Cortex-M3 + 8 Cortex-A53 for the s32g3.

There is a special STM instance called STM_TS which is dedicated to
the timestamp. The 7th STM instance STM_07 is directly tied to the
STM_TS which means it is not usable as a clockevent.

The driver instantiate each STM described in the device tree as a
clocksource and a clockevent conforming to the reference manual even
if the Linux system does not use all of the clocksource. Each
clockevent will have a cpumask set for a specific CPU.

Given the counter is shared between the clocksource and the
clockevent, the STM module can not be disabled by one or another so
the refcounting mechanism is used to stop the counter when it reaches
zero and to start it when it is one. The suspend and resume relies on
the refcount to stop the module.

As the device tree will have multiple STM entries, the driver can be
probed in parallel with the async option but it is not enabled
yet. However, the driver code takes care of preventing a race by
putting a lock to protect the number of STM instances global variable
which means it is ready to support the option when enough testing will
be done with the underlying time framework.

Merge tag 'timers-core-2024-11-18' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip

Pull timer updates from Thomas Gleixner:
"A rather large update for timekeeping and timers:

- The final step to get rid of auto-rearming posix-timers

posix-timers are currently auto-rearmed by the kernel when the
signal of the timer is ignored so that the timer signal can be
delivered once the corresponding signal is unignored.

This requires to throttle the timer to prevent a DoS by small
intervals and keeps the system pointlessly out of low power states
for no value. This is a long standing non-trivial problem due to
the lock order of posix-timer lock and the sighand lock along with
life time issues as the timer and the sigqueue have different life
time rules.

Cure this by:

- Embedding the sigqueue into the timer struct to have the same
life time rules. Aside of that this also avoids the lookup of
the timer in the signal delivery and rearm path as it's just a
always valid container_of() now.

- Queuing ignored timer signals onto a seperate ignored list.

- Moving queued timer signals onto the ignored list when the
signal is switched to SIG_IGN before it could be delivered.

- Walking the ignored list when SIG_IGN is lifted and requeue the
signals to the actual signal lists. This allows the signal
delivery code to rearm the timer.

This also required to consolidate the signal delivery rules so they
are consistent across all situations. With that all self test
scenarios finally succeed.

- Core infrastructure for VFS multigrain timestamping

This is required to allow the kernel to use coarse grained time
stamps by default and switch to fine grained time stamps when inode
attributes are actively observed via getattr().

These changes have been provided to the VFS tree as well, so that
the VFS specific infrastructure could be built on top.

- Cleanup and consolidation of the sleep() infrastructure

- Move all sleep and timeout functions into one file

- Rework udelay() and ndelay() into proper documented inline
functions and replace the hardcoded magic numbers by proper
defines.

- Rework the fsleep() implementation to take the reality of the
timer wheel granularity on different HZ values into account.
Right now the boundaries are hard coded time ranges which fail
to provide the requested accuracy on different HZ settings.

- Update documentation for all sleep/timeout related functions
and fix up stale documentation links all over the place

- Fixup a few usage sites

- Rework of timekeeping and adjtimex(2) to prepare for multiple PTP
clocks

A system can have multiple PTP clocks which are participating in
seperate and independent PTP clock domains. So far the kernel only
considers the PTP clock which is based on CLOCK TAI relevant as
that's the clock which drives the timekeeping adjustments via the
various user space daemons through adjtimex(2).

The non TAI based clock domains are accessible via the file
descriptor based posix clocks, but their usability is very limited.
They can't be accessed fast as they always go all the way out to
the hardware and they cannot be utilized in the kernel itself.

As Time Sensitive Networking (TSN) gains traction it is required to
provide fast user and kernel space access to these clocks.

The approach taken is to utilize the timekeeping and adjtimex(2)
infrastructure to provide this access in a similar way how the
kernel provides access to clock MONOTONIC, REALTIME etc.

Instead of creating a duplicated infrastructure this rework
converts timekeeping and adjtimex(2) into generic functionality
which operates on pointers to data structures instead of using
static variables.

This allows to provide time accessors and adjtimex(2) functionality
for the independent PTP clocks in a subsequent step.

- Consolidate hrtimer initialization

hrtimers are set up by initializing the data structure and then
seperately setting the callback function for historical reasons.

That's an extra unnecessary step and makes Rust support less
straight forward than it should be.

Provide a new set of hrtimer_setup*() functions and convert the
core code and a few usage sites of the less frequently used
interfaces over.

The bulk of the htimer_init() to hrtimer_setup() conversion is
already prepared and scheduled for the next merge window.

- Drivers:

- Ensure that the global timekeeping clocksource is utilizing the
cluster 0 timer on MIPS multi-cluster systems.

Otherwise CPUs on different clusters use their cluster specific
clocksource which is not guaranteed to be synchronized with
other clusters.

- Mostly boring cleanups, fixes, improvements and code movement"

spuriously offered on platforms that won't have the hardware since it's
generally only seen on Arm based platforms. This config is overly
restrictive, while platforms that rely on the SP804 do select it in
their Kconfig there are others such as the Arm fast models which have a
SP804 available but currently unused by Linux. Relax the dependency to
allow it to be user selectable on arm and arm64 to avoid surprises and
in case someone comes up with a use for extra timer hardware.
