IrqConfig GetIrqConfig (size_t index)

Obtains the IRQ number from the interrupt described by the |index|-th element in the interrupt

property.

size_t num_entries ()

May only be called after resolving the IRQ Controller, see |ResolveIrqController()|.

Defined at line 132 of file ../../zircon/kernel/phys/lib/boot-shim/include/lib/boot-shim/devicetree.h

bool NeedsInterruptParent ()

Returns whether additional scans are required to resolve the |interrupt_parent|.

This is only meaningful if |ResolveIrqController| returned false.

Defined at line 139 of file ../../zircon/kernel/phys/lib/boot-shim/include/lib/boot-shim/devicetree.h

fit::result<fit::failed, bool> ResolveIrqController (const devicetree::PropertyDecoder & decoder)

Attempts to either resolve |interrupt-parent| property from the |decoder| hierarchy

or find the |interrupt-controller| along the way.

On success with a return value |true|, the |interrupt-controller| node has been resolved,

On success with a return value |false|,the |interrupt-parent| was resolved but the

|interrupt-controller| has not. On failure, a malformed node or property has been encountered

and no further actions can be performed.
