The PS/2 module in npcx provides a hardware accelerator mechanism
including an 8-bit shift register, a state machine, and control logic
that handle both the incoming and outgoing data. The hardware
accelerator mechanism is shared by 4 PS/2 channels. To support it,
this CL separates the PS/2 driver into channel and controller drivers.
The controller driver is in charge of the PS/2 transaction. The channel
driver is in charge of the connection between the Zehpyr PS/2 API
interface and controller driver.

NPCX WIMU CR_SIN is used to wake up soc from NPCX sleep power state.
The wake-up IRQ enabled when UART init. It causes the wake-up IRQ to
generate many extra interrupt events, which causes the system too busy
to handle other events. This PR moves the UART wake-up IRQ enabling
from UART init to npcx_power_enter_system_sleep() to avoid the

node is a single source of truth defining the CPU frequency. This is

MPS2 AN521 is a dual (Cortex-M33) core where the two cores
have different capabilities. E.g CPU0 implements TrustZone-M,
while CPU1 implements the FPU. Therefore we introcude separate

select the different Cortex-M capabilities. We also update

them get the value from the Kconfig settings, directly.

We should gurantee that we do not use SRAM during Zephyr early

Add a third option for the HFXO capacitance that keeps the default
value of the XOSC32MCAPS register untouched. The message in the above
commit incorrectly claimed that external load capacitors for HFXO
(the reset value of the XOSC32MCAPS register) was the configuration
in effect before. In fact, the register value was modified during
the device trimming in the SystemInit() function to use the internal
capacitors, and that is the configuration required for proper RADIO
operation on nRF5340 DK, for instance.

NPCX7 variants allocate code RAM either at 0x10070000 or 0x10090000.
The MPU requires addresses and region sizes to be aligned, so the
generic cortex_m/arm_mpu_regions.c results in an ineffective setup with
the addresses above.
This adds a custom mpu_regions setup for the npcx7, which covers both
available sizes, resulting in these two possible setups:
- 192kB devices
Code ram: 0x10090000 to 0x100bffff
MPU region: 0x10080000 to 0x100bffff (256k)
- 320kB devices
Code ram: 0x10070000 to 0x100bffff
MPU region 0: 0x10040000 to 0x1007ffff (256k)
MPU region 1: 0x10080000 to 0x100bffff (256k)
In both cases MPU data RAM setting is from 0x200c0000 to 0x200cffff,
matching the generic Cortex-m setup.

Commit f5c6afeccb attempted to avoid
accessing lpc55xxx flash registers in nonsecure mode by conditionalizing
part of the SoC clock initialization routine on whether the flash driver
was enabled. This caused secure applications without the flash driver

any console output. Fix this by changing the condition to depend on
whether we are building a nonsecure image.

Zephyr kernel masks interrupts before calling the SoC PM
sleep entry point. On the Cortex-Mx family this prevents
wake from peripheral interrupts. The SoC PM layer requires
interrupts to wake the SoC and must prevent the CPU from
vectoring to an interrup until PM exit. The SoC does this
by setting ARM NVIC PRIMASK to 1 and BASEPRI to 0. On
return to the kernel SoC sets PRIMASK to 0 allowing ISR's
to fire. In addition the MEC HW only clears its peripheral
sleep enables if the CPU vectors to an ISR. On wake we
clear the MEC PCR sleep control register which clears all
the peripheral sleep enables so peripherals will be active
before exiting the SoC PM layer.
