Add documentation for the serial communication interface (RSCI) found on
the Renesas RZ/G3E (R9A09G047) SoC. The RSCI IP on this SoC is identical
to that on the RZ/T2H (R9A09G077) SoC, but it has a 32-stage FIFO compared
to 16 on RZ/T2H. It supports both FIFO and non-FIFO mode operation. RZ/G3E
has 6 clocks(5 module clocks + 1 external clock) compared to 3 clocks
(2 module clocks + 1 external clock) on RZ/T2H, and it has multiple resets.
It has 6 interrupts compared to 4 on RZ/T2H.

There are two compatible strings defined in "8250.yaml" that require
two clocks to be specified, along with their names:
- "spacemit,k1-uart", used in "spacemit/k1.dtsi"
- "nxp,lpc1850-uart", used in "lpc/lpc18xx.dtsi"
When only one clock is used, the name is not required. However there
are two places that do specify a name:
- In "mediatek/mt7623.dtsi", the clock for the "mediatek,mtk-btif"
compatible serial device is named "main"
- In "qca/ar9132.dtsi", the clock for the "ns8250" compatible
serial device is named "uart"
In commit d2db0d7815 ("dt-bindings: serial: 8250: allow clock
'uartclk' and 'reg' for nxp,lpc1850-uart"), Frank Li added the
restriction that two named clocks be used for the NXP platform
mentioned above.
Change that logic, so that an additional condition for (only) the
SpacemiT platform similarly restricts the two clocks to have the
names "core" and "bus".
Finally, add "main" and "uart" as allowed names when a single clock is
specified.

Pull new SoC support from Arnd Bergmann:
"These five newly supported chips come with both devicetree

- Marvell PXA1908 was the first 64-bit mobile phone chip from Marvell
in the product line that started with the Digital StrongARM SA1100
based PDAs and continued with the Intel PXA2xx that dominated early
smartphones. This one only made it only into a few products before
the entire product line was cut in 2015.
- The QiLai SoC is made by RISC-V core designer Andes Technologies
and is in the 'Voyager' reference board in MicroATX form factor. It
uses four in-order AX45MP cores, which is the midrange product from
Andes.
- CIX P1 is one of the few Arm chips designed for small workstations,
and this one uses 12 Cortex-A720/A520 cores, making it also one of
the only ARMv9.2 machines that one can but at the moment.
- Axiado AX3000 is an embedded chip with relative small Cortex-A53
CPU cores described as a "Trusted Control/Compute Unit" that can be
used as a BMC in servers. In addition to the usual I/O, this one
comes with 10GBit ethernet and and a 4TOPS NPU.

The UART controllers in most Rockchip SoCs are part of power domains
that are always powered on. These always powered on power domains have
typically not been described in the device tree.
Because these power domains have been left out of the device tree there
has not been any real need to properly describe the UART controllers
power domain of Rockchip SoCs.
On Rockchip RK3528 the UART controllers are spread out among the
described PD_RKVENC, PD_VO and PD_VPU power domains. However, one UART
controller belong to an undescribed always powered on power domain.
Add support to describe an optional power-domains for the UART
controllers.

Update the RSCI binding to support an optional secondary clock input on
the RZ/T2H SoC. At boot, the RSCI operates using the default synchronous
clock (PCLKM core clock), which is enabled by the bootloader. However, to
support a wider range of baud rates, the hardware also requires an
asynchronous external clock input. Clock selection is controlled
internally by the CCR3 register in the RSCI block.
Due to an incomplete understanding of the hardware, the original binding
defined only a single clock ("fck"), which is insufficient to describe the
full capabilities of the RSCI on RZ/T2H. This update corrects the binding
by allowing up to three clocks and defining the `clock-names` as
"operation", "bus", and optionally "sck" for the asynchronous clock input.
This is an ABI change, as it modifies the expected number and names of
clocks. However, since there are no in-kernel consumers of this binding
yet, the change is considered safe and non-disruptive.
Also remove the unneeded `serial0` alias from the DTS example and use
the R9A09G077_CLK_PCLKM macro for core clock.

The 8250 binding before converting to json-schema states,
- clock-frequency : the input clock frequency for the UART
or
- clocks phandle to refer to the clk used as per Documentation/devicetree
for clock-related properties, where "or" indicates these properties
shouldn't exist at the same time.
Additionally, the behavior of Linux's driver is strange when both clocks
and clock-frequency are specified: it ignores clocks and obtains the
frequency from clock-frequency, left the specified clocks unclaimed. It
may even be disabled, which is undesired most of the time.
But "anyOf" doesn't prevent these two properties from coexisting, as it
considers the object valid as long as there's at LEAST one match.
Let's switch to "oneOf" and disallows the other property if one exists,
precisely matching the original binding and avoiding future confusion on
the driver's behavior.
