Normal practice is examples only show what the binding document defines and doesn't include consumers in a provider example (or vice-versa). The "qca,ddr-wb-channel-interrupts" and "qca,ddr-wb-channels" properties are also not yet documented by a schema, so avoid (not yet enabled) warnings on them by dropping the interrupt-controller node from the example.

|
The DDR controller of the AR7xxx and AR9xxx families provides an interface to
|
|
flush the FIFO between various devices and the DDR. This is mainly used by
|
|
the IRQ controller to flush the FIFO before running the interrupt handler of
|
|
such devices.
