This patch adds support for the Global Clock Controller on QCom SM4250 and
SM6115, codename bengal. The code is taken from OnePlus repo [1], and the
keyword bengal corresponds to sm4250 and sm6115, so I'm adding both compat
strings.

My bot found errors running 'make DT_CHECKER_FLAGS=-m dt_binding_check'
on your patch (DT_CHECKER_FLAGS is new in v5.13):

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.

This doesn't cover the ability to define pinctrl state both in immediate
nodes and nested one level down. So please mimic how this is done in

Documentation/devicetree/bindings/pinctrl/qcom,sc8180x-pinctrl.yaml

This says that gpio0-9, gpio10-99 and gpio100-179 are valid, but the
driver only presents gpio0-112, so this should be:

^gpio([0-9]|[1-9][0-9]|10[0-9]|11[0-2]$

You only have 114 (113 GPIOs + UFS_RESET) gpios.

Doesn't the &tlmm need to be defined in the example as well?

The wakeup-parent should most likely be &pdc, but feel free to omit
"wakup-parent" from the example if that helps.
