In the SoC that comes on the nRF5340 DK the number of MPU
regions in the nRF5340 Network MCU is 8, instead of 16. We
fix this in DTS by introducing different .dtsi headers for the
different SoC part variants: the nrf340 Engineering A (first
SoC revision, present in the nRF5340 PDK) and the nrf5340
(second SoC revision, present on nRF5340 DK).

As a general rule devicetree properties should correspond to hardware
description or configuration. In cases where a Zephyr driver receives
instance-specific configuration data from a devicetree property that
property should be marked as being Zephyr-specific. Rename
concat-buf-size to zephyr,concat-buf-size to follow this guideline.

The Nordic TWIM peripheral generates a start condition for each bus
transaction. Devices such as the SSD1306 display and some NXP sensors
can only tolerate the presence of a start condition and device address
after a stop condition. Those devices will not operate correctly when
these signals are observed while the bus is already active. This
motivated the addition of a RAM buffer into which message fragments
could be collected so TWIM can transmit them without injecting
unnecessary start conditions.
However many I2C devices interpret these signals as a repeated start
and ignore them and so function properly without a buffer
concatenating the message fragments.
There is no default for the concat-buf-size property, and the previous
strict requirement for one when performing scatter/gather I/O
transactions broke working drivers for devices that tolerate the
repeated starts. Allow those drivers to work by respecting the
property description and attempting to concatenate messages only if a
buffer in which to place them has been provided.

Use the new SFDP infrastructure to read the supported erase type sizes
and commands from the Basic Flash Parameters block. This removes the
need for explicit reference to most block sizes from this driver.
We're also seeing devices where the page size is not 256 bytes.
Accommodate them.

With SFDP support we no longer need to get the JEDEC ID or device size
from devicetree. Make them optional in drivers that have been
converted to support SFDP. When runtime SFDP is not enabled the
presence of the required properties will be verified at build-time.

Allow the devicetree binding for a jedec,spi-nor device to provide the
device capabilities by encoding the Serial Flash Discoverable
Parameters Basic Flash Parameters table in the devicetree node. This
supports applications where a specific flash device will be used and
runtime discovery of device capabilities is not desired.

Add devicetree bindings for the Xilinx AXI GPIO v2 IP. This GPIO
controller has an optional "GPIO2" port, which is not always present.
The Xilinx specific devicetree property names and their meaning match a
subset of what can automatically be generated based on the FPGA logic
design using https://github.com/Xilinx/device-tree-xlnx. These
properties are also used by the Linux kernel.

Add pin controller support for Nuvoton NPCX series
Add pin-mux controller support for Nuvoton NPCX series.
This CL includes:
1. Add pin controller device tree declarations and introduce alt-cells
to select pads' functionality.
2. Add npcx7-alts-map.dtsi since the mapping between IO and controller
is irregular and vary in each chip series.
3. Add nuvoton,npcx-pinctrl-def.yaml and its declarations to change all
pads' functionality to GPIO by default.
4. Pinmux controller driver implementation.

Initial support for Nuvoton NPCX7M6FB SoC of NPCX series which is a chip
family of embedded controllers (EC) and targeted for a wide range of
portable applications. We implemented the SoC skeleton in
soc/arm/nuvoton_npcx since there're many chip families in Nuvoton and
aim to different markets such as PC, General MCU, and Audio. The
architectures and hardware modules are different between them. Hence, we
suggest using the company name plus with chip series for better
understanding.

The FT5336 driver has been improved and generalized so that multiple
Focaltech touch controllers can be supported using the same single
driver. According to specifications the following list of controller
variants should be supported: FT5x06, FT5606, FT5x16, FT6x06, Ft6x36,
FT5x06i, FT5336, FT3316, FT5436i, FT5336i and FT5x46.
Tested using ER-TFTM028-4 display module (FT6X06).
