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:
Error: Documentation/devicetree/bindings/pinctrl/renesas,rzg2l-pinctrl.example.dts:29.34-35 syntax error
FATAL ERROR: Unable to parse input tree

make: *** [Makefile:1418: dt_binding_check] Error 2
\ndoc reference errors (make refcheckdocs):

See https://patchwork.ozlabs.org/patch/1508385

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.

The base patch series required for this path is v5.14-rc2. (I had
mentioned it in the cover letter, maybe I should have added a note
here too)

Sorry for the inconvenience.

Cheers,

I knew that and thought I'd updated my base. But it seems I didn't. Now fixed.

+description:
+  The Renesas SoCs of the RZ/G2L series feature a combined Pin and GPIO
+  controller.
+  Pin multiplexing and GPIO configuration is performed on a per-pin basis.
+  Each port features up to 8 pins, each of them configurable for GPIO function
+  (port mode) or in alternate function mode.
+  Up to 8 different alternate function modes exist for each single pin.
