There is a "native" RTC driver for DS3231 now (maxim,ds3231-rtc, one of
the multiple functions implemented as MFD) so do all we can to
discourage the use of the legacy, counter-API based, driver.
Flag the compatible as deprecated.

The AT25XV021A variant is a flash variant of Atmel's AT25 family
that adds extra protections, requiring additional writes to the
device to program or erase data.
This commit adds a flash driver for AT25XV021A devices instead of
modifying (1) the existing AT45 SPI flash driver or (2) the
existing AT24/25 EEPROM driver because this variant poses
fundamental changes that affect all aspects of the driver.
Notably,
- AT25XV021A includes a second status register, and the format
and functions of the existing status register is
changed from the existing drivers.
- AT25XV021A requires executing page or chip erase commands
before writing, making it incompatible with the
existing AT24/25 EEPROM driver.
- AT25XV021A adds a software protection layer that requires
extra writes before executing program or erase commands.
Tested writing to and erasing from an AT25XV021A device. Tested
reading from an AT25XV021A device across page boundaries. Tested
chip erase function. Tested driver initialization from varying
initial hardware states.

Add EM4 wakeup capable pin mapping to GPIO port node. Pins
capable of EM4 wakeup have dedicated interrupt flags.
Add EM4 as a soft-off power state that is disabled by default.
Marking it as disabled allows users to enter it with
`pm_state_force()`, while preventing the power management
subsystem from selecting the state automatically.

There are 14 TIMG and 2 TIMA, all which can be either a counter or a pwm,
so let's fix the names to avoid ambiguity and enforce uniqueness.
Rule applied here being:
tim<g/a><n>: tim<g/a><n>@<address> {
...
counter<g/a><n>: counter<g/a><n> {
...
};
pwm<g/a><n>: pwm<g/a><n> {
...
};
};
It will be much easier then once get the 16 timer nodes included.

Those memories should be disabled by default and enabled
at application level.
Incidentally, fix the way Kconfig symbol is enabled as
we should not parse status of ramcfg, but status of enabled
memory nodes.

Remove the universal, unconditional declaration of the RAM area
at the SoC level, due to:
- the hardcoded base address 0 overlapping the exception vectors,
the ATCM and the BTCM areas.
- the availability of the BTCM not being guaranteed unconditionally
(config pin dependant)
- the possibility of having a 'black hole' between the ATCM and
the BTCM depending on the operating mode of the R-cores cluster,
which leads to a part of the text section being unavailable
- qemu not properly implementing the configuration-dependant
behaviour of the ATCM and BTCM areas.

Because the EC host command with SHI/SPI backend is timing sensitive, it
required the CPU to response the SHI interrrupt as soon as possible.
This commit re-arranges the default interrupt priority by:
1. keep the SHI's interrupt priority to 1.
2. Decrease the priority of the other peripherals by 1.
(i.e. increase the priority `value` by 1)

When compiling, the following warning occurs:
Warning (simple_bus_reg): /soc/sai1@452005804: simple-bus unit address
format error, expected "52005804"
Looking at table 3 in the reference manual[1] for the stm32n6 it seems that
the sai1_a address simply had a typo, where a "4" was added in front of the
correct address.
Fix the typo.

Add tearing effect support for better display synchronization. If
tearing effect is configured in the mipi_dbi device, the display
controller configures its tearing effect register.
Display orientation configuration is updated to also rotated the
direction of the display pixel vertical scanline, such that scan order
matches the display orientation.

Add tearing effect support for better display synchronization. This
allows users to configure an external interrupt on falling/rising edges
of the gpio connected to the display controllers tearing effect pin.
See dt-bindings/mipi_dbi/mipi_dbi.h for details of how this works for
mipi_dbi display interfaces.

1. Added new boolean type 'nxp,internal-voltage-regulator-en'
and 'nxp,chop-oscillator-en' properties for 'nxp,vref'.
The user can use these properties to improve the stability
and accuracy of the VREF output voltage.
2. Added properties 'nxp,current-compensation-en' and
'nxp,internal-voltage-regulator-en' and 'nxp,chop-oscillator-en'
for LPC55S3x, MCXN23x, MCXN94x, and MCXW7x VREF node.

RP2350 adds four more PWM slices from the eight available on RP2040,
which are only broken out to package pins on RP2350B. This change fixes
the driver to support the correct number of slices on RP2350.
Tested by confirming that PWM can correctly be configured on GPIO 44 of
RP2350B.

Which does not have HW support for it, as stated by ST here:
https://www.st.com/en/microcontrollers-microprocessors/stm32u575-585.html
"
The STM32U575 portfolio offers from 1 to 2 Mbytes of flash memory
and from 48- to 169-pin packages.
The STM32U585 is available with 2 Mbytes of flash memory and provides
an additional encryption accelerator engine (AES, PKA, and OTFDEC).
"
All the U5 SoC have a hash HW accelerator (even the ones which don't
have crypto support: U535XX, U575XX, U59XXX and U5FXXX).
The hash node is therefore moved directly inside the stm32u5.dtsi.
