I had this question because we have below info in the patch
"dt-bindings: add binding for i.MX8MQ IOMUXC":

diff --git a/Documentation/devicetree/bindings/pinctrl/fsl,imx8mq-pinctrl.txt b/Documentation/devicetree/bindings/pinctrl/fsl,imx8mq-pinctrl.txt
new file mode 100644

...
+       Refer to imx8mq-pinfunc.h in device tree source folder for all available
+       imx8mq PIN_FUNC_ID.
