a00bb94c7b dt-bindings: i2c: gpio: Add properties for dealing with write-only SDA/SCL w/o pullup
There are slave devices that understand I2C but have read-only SDA and
SCL. Examples are FD650 7-segment LED controller and its derivatives.
Typical board designs don't even have a pull-up for both pins.
Therefore add properties for not using open-drain. For write-only SCL
we have a property already, add one for write-only SDA.

0a4eecf96c dt-bindings: i2c: renesas,rzv2m: Fix SoC specific string
The preferred form for Renesas' compatible strings is:
"<vendor>,<family>-<module>"

Somehow the compatible string for the r9a09g011 I2C IP was upstreamed
as renesas,i2c-r9a09g011 instead of renesas,r9a09g011-i2c, which
is really confusing, especially considering the generic fallback
is renesas,rzv2m-i2c.

The first user of renesas,i2c-r9a09g011 in the kernel is not yet in
a kernel release, it will be in v6.1, therefore it can still be
fixed in v6.1.
Even if we don't fix it before v6.2, I don't think there is any
harm in making such a change.

s/renesas,i2c-r9a09g011/renesas,r9a09g011-i2c/g for consistency.

7a2f36828c dt-bindings: cros-ec: Reorganize and enforce property availability
Various properties in the cros-ec binding only apply to different
compatible strings. For example, the interrupts and reg property are
required for all cros-ec devices except for the rpmsg version. Add some
conditions to update the availability of properties so that they can't
be used with compatibles that don't support them.

This reveals that many of the examples in bindings that use cros-ec were
missing the interrupts property. Add the property to make those bindings
whole again.

e7c2194046 dt-bindings: i2c: migrate mt7621 text bindings to YAML
SoC MT7621 I2C bindings used text format, so migrate them to YAML.
There are some additions to the binding that were not in the original
txt file. This binding is used in MT7621 and MT7628a Ralink SoCs. To
properly match both dts nodes in tree we need to add to the schema
'clocks', 'clock-names' and 'reset-names'. Both 'clock-names' and
'reset-names' use 'i2c' as string so maintain that as const in
the schema. Also, Properly update MAINTAINERS file to align the
changes.

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.
