I'm not talking about that. I mentioned different API call.
/**
* fwnode_property_match_property_string - find a property string value in an array and return index
* @fwnode: Firmware node to get the property of
* @propname: Name of the property holding the string value
* @array: String array to search in
* @n: Size of the @array
*
* Find a property string value in a given @array and if it is found return
* the index back.
*
* Return: index, starting from %0, if the string value was found in the @array (success),
* %-ENOENT when the string value was not found in the @array,
* %-EINVAL if given arguments are not valid,
* %-ENODATA if the property does not have a value,
* %-EPROTO or %-EILSEQ if the property is not a string,
* %-ENXIO if no suitable firmware interface is present.
