In arch/arm/boot/dts/uniphier-pinctrl.dtsi, there are child nodes of
pinctrl that defines pinmux and pincfg, however, there are no rules
about
that in dt-bindings.

'make dtbs_check' results an error with the following message:

pinctrl: 'ain1', 'ain2', 'ainiec1', 'aout', 'aout1', 'aout2', ...
... 'usb2', 'usb3' do not match any of the regexes: 'pinctrl-[0-9]+'

To avoid this issue, add the rules of pinmux and pincfg in each child
node
and grandchild node.

After coming up with this hack, I found a better way using
additionalProperties:

additionalProperties:
type: object

I see. I'll add it next.

and then all this:

Same thing here.

Yes. I'll add it, too.

Thank you,
