Subject: [PATCH v3] dt-bindings: pinctrl: update uart/mmc bindings for MT7986 SoC

From: Frank Wunderlich <[email protected]>

Some pinmux pins of the mt7986 pinctrl driver is composed of multiple
pinctrl groups, the original binding only allows one pinctrl group
per dts node, this patch sets "maxItems" for these groups and add new
examples to the binding documentation.

Fixes: 65916a1ca90a ("dt-bindings: pinctrl: update bindings for MT7986 SoC")

sorry, messed up email-list, so resend it

v3:
- squashed version from sam
- v2 was ack'd by Krzysztof, but sams patch included updated emmc-names
and different structure for uart to allow 2 pingroups
v2:
- wrap on col 80

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:

doc reference errors (make refcheckdocs):

See https://patchwork.ozlabs.org/patch/

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.
