[PATCH v2 24/40] dt-bindings: pinctrl: qcom,sc7280-pinctrl: do not require function on non-GPIOs

From: Krzysztof Kozlowski
Date: Mon Sep 12 2022 - 02:19:52 EST


Certain pins, like SDcard related, do not have functions and such should
not be required:

sdc1-clk-pins: 'function' is a required property

Signed-off-by: Krzysztof Kozlowski <krzysztof.kozlowski@xxxxxxxxxx>

Another question is whether 'function' should be disallowed for such
pins?
