There are currently modem_cmd_send() and modem_cmd_send_nolock()
functions, each with slightly different behavior regarding acquiring (or
not) sem_tx_lock. Introduce a generic function that will allow caller to
select behavior using flags.
While at it, add possibility to disable setting and unsetting command
handlers. This will be useful in situations when there are multiple
replies expected one after the other coming as a response to single
command. This is the case for example with ESP-AT driver, which expects
following data as response to AT+CIPSEND command:
OK
>
where 'OK' is handled by static CMD_RESP (so releasing response
semaphore right away), while '>' is handled by dynamic
CMD_HANDLER (which is releasing another semaphore). Keeping command
handlers in place allows to receive '>' without race condition because
of small period of time where command handlers are not set.
Convert modem_cmd_send_nolock() and modem_cmd_send() to static inline
functions, as they are just a specific invocation of
modem_cmd_send_ext() function.

Add a shim that allows using the nrfx I2S driver via the Zephyr API.
Add also missing devicetree nodes representing the I2S peripherals
in the nRF52 Series SoCs.
Extend the "nordic,nrf-i2s" binding with a new property that allows
specifying the clock source to be used by the I2S peripheral (so that
it is possible to use HFXO for better accurracy of the peripheral clock
or, in the nRF53 Series SoCs, to use the dedicated audio oscillator).

Create version 2 of the MEC GPIO driver to support MEC172x to not
interfere with MEC152x. When the MEC172x ECIA interrupt aggregator
driver is ready, this driver will use ECIA for registering GPIO
interrupt callbacks instead of maintaining its own interrupt table.
Add V2 DT binding.
Add the Kconfig configuration settings for the MEC172x GPIO
V2 driver at the SoC and board level.
Add port id to DT allowing use of DT FOR EACH macro in the driver.

created from DT nodes with a compatible property matching "ti,ina23x".
The following datasheets were referenced while developing the driver:

Voltage: 5V
Measured Values:
Voltage: 5.1 V

Use `dma_reload()` instead of `dma_config()` within DMA callbacks. This
significantly shortens time required to reconfigure DMA engine to
transmit / receive the next data block and allows to configure higher
I2S bus data rates.
The maximum I2S data rate supported by the driver is still lower than
that of underlying hardware. To fully support hardware capabilities the
I2S driver would have to use scatter-gather / linked-list DMA transfer.
This is currently not supported by the DMA driver.

The KBC/ACPI event data is 4-byte in width and composed of
event/data/type fields. However, the field position is defined by each
chip vendor via macro and not unified in the current implementation.
The commit uses the structure bit field to define and unify the field
position. It helps the application access it with a common approach.

Add driver implementation and header files for a MEC172x
aggregated interrupt driver. Enable the parent(ECIA) node
to have the driver initialize interrupt hardware for use.
Enable child nodes for those GIRQs used for aggregation.
Refer to chip documention for the list of GIRQs restricted
to aggregation and those which support direct mode.
Add chip level device tree node for MEC172x EC interrupt
aggregator parent and GIRQ children. Each child node contains
a list of sources representing the source bit position in the
GIRQ registers.
Add DT bindings for ECIA and GIRQ nodes.
Add build file(s) and configuration items for the MEC172x ECIA
aggregated interrupt driver. Add and enable the MEC172x interrupt
driver on the MEC172x evaluation board(EVB). Enable parent node to

Add basic counter driver based on Timer Counter (TC) module for Atmel
SAM family.
Remarks:
- The driver is not thread safe.
- The driver does not implement guard periods.
- The driver does not guarantee that short relative alarm will trigger
the interrupt immediately and not after the full cycle / counter
overflow.

This commit introduces an automatic recovery procedure in cases an
entropy source error was detected.
- On Series with soft reset support a soft rest is executed.
- On Series w/o soft reset support the pipeline is cleared by reading

Because these two functions are called from threads and ISR.
And they run a bit-wise OR operation on the interrupt registers.
So protect them to prevent race condition between thread and ISR
context where causing an interrupt won't enable as expected.
eg.
- Pseudo code of thread enable IER1's bit1:
1. load word from IER1 (0x40) and write into CPU register S1
=> S1=0x40
2. Or S1's bit1
=> S1=0x42
(But if an interrupt is triggered here)
3. Store word to IER1 from S1
=> IER1=0x42
(IER1 will be 0x42 not 0x43, IER1's bit0 is disable again due to the
race condition above)
-Pseudo code of ISR enable IER1's bit0
1. load word from IER1 (0x40) write into CPU register S2
=> S2=0x40
2. Or S2's bit0
=> S2=0x41
3. Store word to IER1 from S2
=> IER1=0x41
4. Go back to thread.
