Revert "dts: bindings: LPtimer of stm32 has a x2 factor on its clock"
The stm32u5 lptim clock source has no prescaler to divide the
the LPTIM input clock frequency : no property required.
This reverts commit 572b286010.

r8a779f0 is also know as S4, this SoC is part of the Gen4 SoC series,
has 8 Cortex-A55 and a dual core lockstep Cortex-R52 processor.
SCIF0 is dedicated to Zephyr and SCIF3 to Linux.
**Control Domains**
IMPORTANT: This SoC is divided into two "domains":
- Application domain contains some peripherals as well as A55 & R52 cores.
- Control domain that contain a G4MH/RH850 MCU and other peripherals.
In order to access control domain peripherals such as gpio4-7 and CAN-FD
from application domain, the G4MH MCU has to unlock a protection
mechanism from control domain buses.
"Protected" controllers will be flagged in gen4 device trees,
warning users that they need to flash a custom G4MH firmware
to unlock access to these controllers.
**Clock controller**
This SoC clock controller is offering "domains"
for each world (Zephyr/Linux).
These domains are several "entry points" to the clock controller
which are arbitrated to avoid a world from turning off a clock needed
by another one.
We decided to use the same domain as Linux because the
security mechanism as to be implemented before accessing
another domain.

The shi module in npcx4 supports the enhanced buffer mode.
Add a new compatible string "nuvoton,npcx-shi-enhanced" for it.
Then the shi driver can determine if it should use the enhanced buffer
mode based on the compatiable string.

This add regulator driver for Smartbond DA1469X SOC.
Driver can control VDD, V14, V18, V18P, V30 rails,
full voltage range supported by SOC is covered.
For VDD, V14, V18, V18P DCDC can be configured.
Special VDD_CLAMP (always on) and VDD_SLEPP are added
to allow configuration of VDD in sleep modes.

Add an option to drive inactive columns to inactive state rather than
high impedance. This is useful if the matrix has isolation diodes for
every key, as it allows the matrix to stabilize faster and the API for
changing the pin value is more efficient than the one to change the pin
configuration.

Add soc power management for the STM32F4x chips.
One low power state is added supported by all chips from the family -
the Stop mode with voltage regulator in low-power mode.
The Stop mode for STM32F chips has to work with the IDLE timer -
CORTEX_M_SYSTICK_IDLE_TIMER, because PLL and HSI are disabled in the
Stop mode (Systick is not clocked). The only possible wakeup source is
RTC, which works as a IDLE timer for the Systick.
The exit latency may need to be adjusted per system, depending on the
system tick frequency and other variables.

On STM32WL, the backup memory is defined as part of the TAMP peripheral.
This seems to be a deviation from the stm32 family where this memory is
defined as part of the RTC.
The STM32WL reference manual shows that tamp_pclk is connected to
rtc_pclk. This means that the clock required to run the TAMP peripheral
is the same as the RTC's. A quick port of BBRAM on STM32WL is achieved
by instanciating the bbram device as a child of the RTC and by modifying
the address offset to the first backup register from the rtc base
address.

This commit introduces the SOF host DMA driver.
This driver is used by NXP platforms in the context of
SOF's host component to copy data from the host memory
to the firmware (local) memory. This is possible because
NXP platforms can access the host memory directly w/o
an actual DMA engine.

Split the common keyboard scanning code out of the ITE specific driver
and use the generic code instead.
Note that this changes few timing defaults, the change is not
significant though so I suspect there's no difference in practice.

Setting slew-rate property is not supported on Kinetis KE series
and the value will not have effect, so this property should not
be required.
We are also planning to reuse the Kinetis pin control binding and
associated driver for NXP S32K1xx devices, which doesn't support
setting the slew-rate rate as well.
