Polling mode is enabled if the "interrupts" property is missing.
Thus, this commit deletes "interrupts" entry from "required" section
and adds a description for the fallback to polling mode at the
"interrupts" entry.

Add dedicated samsung,exynos8895-uart compatible to the dt-schema for
representing uart of the Exynos8895 SoC.
Like GS101, it has a required DT property samsung,uart-fifosize, but
it does not exhibit the 32 bit register access limit.

This binding currently duplicates the permitted clock-names in various
places, and when adding more compatibles, clock-names will have to be
duplicated even more.
The reason is:
1) subschemas (-if: ...), still have to match the top-level:
pattern: '^clk_uart_baud[0-3]$'
2) there is one compatible that doesn't follow sequential numbering for
the clock names (samsung,s3c6400-uart)
3) when limiting the number of clock-names, we also want to enforce
sequential names
Because of 1) and 2), the patterns can not simply be changed to
constant strings, and later overridden in a different subschema (for
samsung,s3c6400-uart only).
Since we can't populate the top-level clock-names based on the
compatible, and because when limiting the number of items we generally
want sequential numbers and not a pattern, move the permitted strings
into a subschema of its own and populate it based on the compatible:
* 'uart clk_uart_baud2 clk_uart_baud3' for the one outlier
* 'uart clk_uart_baud0..3' for everything else
This way we can avoid having to duplicate the permitted names
everywhere.
While at it, add blank lines as per the universal style, which is to
have blank lines between properties, except where they are booleans.
Also add another example using a compatible that uses the default
clock-names scheme, as opposed to the existing example that uses
samsung,s3c6400-uart's non-default clock-names. This allows testing
both versions of the clock-names property when running
dt_binding_check.

SCIF support
Document support for the Serial Communication Interface with FIFO (SCIF)
available in the Renesas RZ/V2H(P) (R9A09G057) SoC. The SCIF interface in
the Renesas RZ/V2H(P) is similar to that available in the RZ/G2L
(R9A07G044) SoC, with the following differences:
- RZ/V2H(P) SoC has three additional interrupts: one for Tx end/Rx ready
and two for Rx and Tx buffer full, all of which are edge-triggered.
- RZ/V2H(P) supports asynchronous mode, whereas RZ/G2L supports both
synchronous and asynchronous modes.
- There are differences in the configuration of certain registers such
as SCSMR, SCFCR, and SCSPTR between the two SoCs.
To handle these differences in the driver, a new SoC-specific compatible
string is added, ensuring proper handling of the unique features and
register configurations of the RZ/V2H(P) SoC.

The Marvell PXA SSP block is the same or similiar to the MMP2 variant.
The only difference in the binding is the PXA version supports DMA (and
that's probably a binding difference rather than an actual h/w
difference).
The old binding didn't belong under 'serial' as it is not a UART. The
SSP block also supports audio devices, so 'spi' is not a perfect fit
either. As the existing schema for MMP2 is there, just leave things
as-is.
The examples in the old text binding were pretty out of sync with
reality. 'clock-names' and 'ssp-id' aren't documented nor used.

Pull more SoC devicetree updates from Arnd Bergmann:
"This is a follow-up to an earlier pull request for device tree
changes, as three platform maintainers sent their contents too late to
be included in the main set, but had not caused any further problems
since then:
- The Amlogic platform now containts support for two new SoC types,
the A4 and A5 chips for audio applications. Both come with a
reference board, and one more dts file gets addded for the
combination of the MNT Reform Laptop with the BPI-CM4 CPU module
- The ASpeed platform adds support for six addititional server
platforms that use ast2500 or ast2600 as their BMC, while another
one gets removed
- The RISC-V platforms from Microchip, Starfive and and T-HEAD get
additional features for existing hardware, plus the addition of the
Milk-V Mars based on the StarFive VisionFive v2 board"

Convert the Broadcom BCM2835 Auxiliary UART to newer DT schema.
Created DT schema based on the .txt file which had
`compatible`, `reg` `clocks` and `interrupts` as the
required properties. This binding is used by Broadcom BCM2835
SOC used in some Raspberry PI boards.
Changes from original file:
Implemented complete example which the original txt binding lacked.

access-controllers is an optional property that allows a peripheral to
refer to one or more domain access controller(s).
Description of this property is added to all peripheral binding files of
the peripheral under the STM32 firewall controller. It allows an accurate
representation of the hardware, where various peripherals are connected
to a firewall bus. The firewall can then check the peripheral accesses
before allowing its device to probe.
