PCI: dwc: Use of_property_present() for non-boolean properties

[PATCH] PCI: dwc: Use of_property_present() for non-boolean properties

Posted by Rob Herring (Arm) 2 weeks, 5 days ago

The use of of_property_read_bool() for non-boolean properties is
deprecated in favor of of_property_present() when testing for property
presence.
