is suspended. When active sampling resumes at the configured rate.
When suspended fetch/get will return an errno and 0'ed out samples.

If for any reason the timer counter didn't hold a value close enough to
zero on boot then the cycle delta could overflow and the reported ticks
won't be right. Those who really want the hardware uptime where this
makes sense (as opposed to Zephyr's uptime) can still rely on
sys_clock_cycle_get_64().

Enabled simultaneous support by adding a DTS variable named “io-mapped”.
There are 3 possibilities through instance in dtsi file.
Under PCIe, PCIe ns16550.
Under soc and has a variable io-mapped, legacy(IO mapped).
Under soc and don’t have a variable io-mapped, MMIO mapped.
Simultaneous access can be enabled by a Kconfig.
For PCIe instances UART initialization should be done post-kernel as it
depends on PCIe initialization.

GPT timer driver previously used "restart mode", where the timer would
count to a given value, then rollover. In this mode, "Any write access
to the Compare register of Channel 1 will reset the GPT counter". Since
a write to the compare register takes affect after 1 cycle of the
module's bus clock, and the bus clock is not synchonized with the GPT
module's low frequency counter clock, writing to the compare register
will induce a counter reset, and can cause the GPT to lose time
synchronization. This can induce time drift over time.
To fix this, rework the GPT driver to use "free run" mode. Note that
free run mode is not used directly, rather the GPT is configured to
reset on a tick boundary at boot, and then the second compare register
is used to set capture points. This way, the GPT interrupt will always
fire at a tick boundary, and no calculations are needed to handle
the counter rollover.

Added a new watchdog driver which can handle a multiple wdt_dw instances
and can control the pause signal.
The mlt platform has three designware watchdogs, one for each core.
I decided to create a separate intel watchdog driver for the following
reasons:
1. All three devices share the same interrupt number. Each watchdog reports
an interrupt to the core to which it has been assigned. The same interrupt
number cannot be used by multiple devices in the device tree. So, it would
be assigned to only one device. The other dw watchdog devices would use
this assignment, even though it would not be described for them in the dt.
The interrupt handler function in dw watchdog checks the interrupt flag.
If the interrupt was connected to the first watchdog, and the second or
third watchdog signal an interrupt, the interrupt handler of the first
device would ignore it because it would not have set the interrupt flag.
The watchdog device don't knows anything about the existence of the others
devices.
2. The designware watchdog only supports a hardware pause signal. It cannot
be paused programmatically. On the mtl platform, there is a separate group
of control registers for all per-core watchdogs. There are GPIO-like
registers that allows control of a hardware pause signal for subordinate
watchdogs. This separate block is shared by all three watchdogs.
3. The base addresses of the subordinate watchdogs are read from the
aforementioned control registers. As a result, in the device tree we have
only one base address for the intel watchdog, which points to the pause
control registers and containing the base addresses of the subordinate
devices.

There are some needs to attach and reattach i3c/i2c devices at runtime
Some I2C devices can have special registers where the address can be
changed at runtime. Also some I3C devices can be powered off at runtime
freeing up the address space they take up. These new APIs allow for these
to be changed at runtime. This also moves some config/data in to a common
i3c config/data structure which would allow the api to operate on to be
common for all I3C drivers.

Introduce flash extended operations that can be used to disable access
to option and control registers until reset. Disabling access to these
registers improves system security, because flash content (or protection
settings) can't be changed even when exploit was found.
On STM32 devices, registers can be locked until reset by writing wrong
key during unlock procedure. It triggers a bus fault, so during the
procedure we need to ignore faults and clear bus fault pending bit.
Please note that option register disabling was implemented for devices
that have OPTCR register (F2, F4, F7 and H7). Implementation on other
devices requires more testing, since documentation is not precise
enough. Disabling control register was implemented for devices that
have CR register.

This patch makes possible to choose custom byte which should be used
to enable non-permanent readout protection (RDP1). Actually, any byte
except 0xAA and 0xCC (which are used by RDP0 and RDP2 respectively)
can be used to enable RDP1 but in multi-image environment, some other
image could check if RDP1 is enabled by comparing it to some hardcoded
value.
If property is not defined, 0x55 will be used to enable RDP1. The
default value comes from STM32 HAL.

family. These devices can enable protection on entire flash content.
Readout protection functionality was exposed as vendor extended

Enabling readout protection permanently or disabling readout protection
(changing from level 1 to level 0) is guarded by

CONFIG_FLASH_STM32_READOUT_PROTECTION_DISABLE_ALLOW respectively.

- That MIN_DELAY is a magic arbitrary number that is never going to be
right for all cases. Get rid of it in favor of a smarter solution.
- `sys_clock_set_timeout()` should not base its next match value on the
current time. Tracking the `last_tick` and `last_elapsed` values avoids
the need for all the tick rounding computation.
- Clamp the next timeout to HPET_MAX_TICKS/2. This leaves room for the
added elapsed time and any possible IRQ servicing delay.
