caad8883e4 dt-bindings: i2c: renesas,riic: Document the R9A08G045 support
Document the Renesas RZ/G3S (R9A08G045) RIIC IP. This is compatible with
the version available on Renesas RZ/V2H (R9A09G075).

2362c73002 dt-bindings: i2c: adjust indentation in DTS example to coding style
Bindings coding style expects 2- or 4-space indentation in the DTS
example.  Correct files having something odd (6- or 8-space) to 4-space
while re-ordering few properties according to DTS coding style (the
first property should be compatible, then reg/ranges).  No functional
impact.

c1f39c62eb dt-bindings: i2c: renesas,riic: Document R9A09G057 support
Document support for the I2C Bus Interface (RIIC) available in the
Renesas RZ/V2H(P) (R9A09G057) SoC.

The RIIC interface in the Renesas RZ/V2H(P) differs from RZ/A in a
couple of ways:
- Register offsets for the RZ/V2H(P) SoC differ from those of the
  RZ/A SoC.
- RZ/V2H register access is limited to 8-bit, whereas RZ/A supports
  8/16/32-bit.
- RZ/V2H has bit differences in the slave address register.

To accommodate these differences, a new compatible string
"renesas,riic-r9a09g057" is added.

de917701da dt-bindings: i2c: renesas,riic: Document RZ/Five SoC
The RIIC block on the RZ/Five SoC is identical to one found on the RZ/G2UL
SoC. "renesas,riic-r9a07g043" compatible string will be used on the
RZ/Five SoC so to make this clear, update the comment to include RZ/Five
SoC.

No driver changes are required as generic compatible string
"renesas,riic-rz" will be used as a fallback on RZ/Five SoC.

4e2a2ed96a dt-bindings: i2c: renesas,riic: Fix 'unevaluatedProperties' warnings
With 'unevaluatedProperties' support implemented, there's a number of
warnings when running dtbs_check:

arch/arm64/boot/dts/renesas/r9a07g043u11-smarc.dtb: i2c@10058000: Unevaluated properties are not allowed ('resets' was unexpected)
	From schema: Documentation/devicetree/bindings/i2c/renesas,riic.yaml

The main problem is that bindings schema marks resets as a required
property for RZ/G2L (and alike) SoC's but resets property is not part
of schema. So to fix this just add a resets property with maxItems
set to 1.

Now the I2C device nodes in all DTS files have gained "interrupt-names"

112dfa5ca1 dt-bindings: i2c: renesas,riic: Add interrupt-names
The Renesas RZ/A and RZ/G2L I2C Bus Interface has no less than 8
interrupts.  Hence document the "interrupt-names" property, to make it
easier to review the interrupt mappings in DTS files.

Note that this property cannot be made required yet, as the RIIC nodes
in all DTS files lack the property.
