[v3] pinctrl/arm64: qcom: continued - fix Qualcomm TLMM pinctrl schema warnings

[PATCH v3 07/34] dt-bindings: pinctrl: qcom,tlmm-common: add common check for function

Posted by Krzysztof Kozlowski 3 years, 6 months ago

Certain pins, like SDcard related, do not have functions and such should
not be required.  Add a check for this in common Qualcomm TLMM pin
controller schema.
