The POSIX_MAX_FDS option does not correspond to any standard
POSIX option. It was used to define the size of the file
descriptor table, which is by no means exclusively used by
POSIX (also net, fs, ...).
POSIX_MAX_FDS is being deprecated in order to ensure that
Zephyr's POSIX Kconfig variables correspond to those defined in
the specification, as of IEEE 1003.1-2017. Namely,
POSIX_OPEN_MAX. CONFIG_POSIX_MAX_OPEN_FILES is being deprecated
for the same reason.
To mitigate any possible layering violations, that option is
not user selectable. It tracks the newly added
CONFIG_ZVFS_OPEN_MAX option, which is native to Zephyr.
With this deprecation, we introduce the following Kconfig
options that map directly to standard POSIX Option Groups by
simply removing "CONFIG_":
* CONFIG_POSIX_DEVICE_IO
Similarly, with this deprecation, we introduce the following
Kconfig options that map directly to standard POSIX Options by
simply removing "CONFIG":
* CONFIG_POSIX_OPEN_MAX
In order to maintain parity with the current feature set, we
introduce the following Kconfig options.
* CONFIG_POSIX_DEVICE_IO_ALIAS_CLOSE
* CONFIG_POSIX_DEVICE_IO_ALIAS_OPEN
* CONFIG_POSIX_DEVICE_IO_ALIAS_READ
* CONFIG_POSIX_DEVICE_IO_ALIAS_WRITE
Gate open(), close(), read(), and write() via the
CONFIG_POSIX_DEVICE_IO Kconfig option and move
implementations into device_io.c, to be conformant with the
spec.
Lastly, stage function names for upcoming ZVFS work, to be
completed as part of the LTSv3 Roadmap (e.g. zvfs_open(), ..).

This commit refactors the Intel SSP DAI driver to support dynamic
management of SSP IP. This change additionally separates the
management of the DAI part from the management part of the SSP IP.
Key changes:
- Add new static functions to manage SSP IP power.
- Update the DAI SSP configuration functions to use the new management
approach.
- Update device tree bindings and instances to reflect the new SSP IP
management mechanism.
- ace30 (PTL) support.

In the Intel platforms most of HPSRAM is used by modules when
are required. By default all these banks are powered off and are
enabled by L2 MM driver only when needed.
At the driver initialisation each unused page is unmaped and
when whole HPSRAM bank is unused the power is switched off.
Since mapping memory in MMU TLB and flushing it at system start is
not needed and time consuming, this patch modifies the init
sequence to avoid it.
Additionally it adds MMU maping and unmaping for pages allocated
from unused pool.

The commit adds and no_explicit_erase capability to flash_parameters,
that indicates whether device is program-erase type device; such
devices, like Flash type devices, require erase prior to writing
random data at any previously programmed location.
This capability should only be set by drivers.
The flash_params_get_erase_cap() function has been added, for parsing
flash_parameters object to obtain erase capabilities of device.
The function returns capabilities as combination of bits representing
them. Currently it will return:
0 -- no erase capabilities
FLASH_ERASE_C_EXPLICIT -- erase required before write of random data.
Additional capabilities have been reserved but are not yet used.
There are following Kconfig options added:
FLASH_HAS_EXPLICIT_ERASE
FLASH_HAS_NO_EXPLICIT_ERASE
that should be selected by device driver to indicate whether
devices served by driver needs erase prior to write.
The above Kconfigs are used to figure out whether app is built
for hardware that requires erase prior to write.
They can be also used to detect that it is attempted to build
some subsystem that will not work with provided hardware, for example
file system that has not been prepared to work with devices that
do not require erase.

This commit should deal with the followings:
1. PLL requires that VDD level be changed to 1V2 and then released
to 0V9 when it's turned off. Changing the VDD level should be
done when the regulator driver is available. Otherwise, the VDD
level will be fixed to 1V2 (reset value).
2. Check if PLL is allowed to be turned off as it might happen that
USB is enabled which is clocked by PLL.
3. Do not wait for the PLL to lock. This is now performed silently
when PLL is requested.
4. Before switching to PLL we should check if PLL is already enabled
as it might happen that PLL node is initially disabled.

driver to work when PM is enabled. The sleep state is bound to the
counter start/stop functionality. TIMER3/4 block instances are

This patch adds a timeout to the clock_control_on() implementation. The
reason for this timeout is to prevent system freezes when the PLL is
configured incorrectly, or, if BICR is wrong. The locking time of the
AUXPLL is <30us, however, when it starts it also starts other
dependencies which take much longer to become ready. The locking time
has been experimentally measured to be around 2ms, so a 10x bound has
been added.

These devices have a somewhat odd hybrid design, with a free-running
64 bit up counter but no comparator. Instead interrupts are triggered
by (one of an array of) 32 bit down counters with reset (a-la SysTick,
but without the 24 bit precision issues). The combination actually
results in a fairly simple driver as we can skip the comparator
rounding math.
