-Subject: [PATCH 216/226] dpaa2-evb: Fix interrupt handling
-
-Mask only the events handled by the driver - DPDMUX_IRQ_EVENT_LINK_CHANGED.
-
-Use clear-on-read mechanism for the interrupt status and avoid calling
-dpdmux_clear_irq_status(). Status contains the events handled (only link
-state change for the moment) and masks the first 16-bits, as they are used
-to store the interface ID that generated the event.
-
