This patch series addresses the conversion of the I2C DT binding
for Atmel/Microchip SoCs to Device Tree Schema format. The
SAMA7G5 compatible has also been added to the I2C DT binding. It also
ensures consistency across the SoC files regarding the ordering
of the `rx` and `tx` strings of the `dma-names` property of the
`i2c` nodes by changing it in the SoC file of `sama7g5`.

Swap `rx` and `tx` for the `dma-names` property of the `i2c` nodes
in order to maintain consistency across Microchip/Atmel SoC files.

My bot found errors running 'make DT_CHECKER_FLAGS=-m dt_binding_check'
on your patch (DT_CHECKER_FLAGS is new in v5.13):
yamllint warnings/errors:
dtschema/dtc warnings/errors:
Documentation/devicetree/bindings/i2c/atmel,at91sam-i2c.example.dt.yaml:0:0: /example-0/i2c@f8034600/eeprom@1a: failed to match any schema with compatible: ['wm8731']
doc reference errors (make refcheckdocs):
See https://patchwork.ozlabs.org/patch/1603370
This check can fail if there are any dependencies. The base for a patch
series is generally the most recent rc1.
If you already ran 'make dt_binding_check' and didn't see the above
error(s), then make sure 'yamllint' is installed and dt-schema is up to
date:
pip3 install dtschema --upgrade
Please check and re-submit.

It seems this is undocumented compatible. Could you use something else,
documented?

This looks not needed, because it contains microchip,sam9x60-i2c which
is mentioned earlier.

Hmm, I might have misunderstood the functionality. I thought it would be
stricter, having to match all the strings of that compatible. I guess
something like this should be enough then?
oneOf:
- enum:
- atmel,sama5d4-i2c
- atmel,sama5d2-i2c
- microchip,sam9x60-i2c
- microchip,sama7g5-i2
Just adding the sama7g5 compatible seems to pass the check on my end.
