7 title: Intel Local Advanced Programmable Interrupt Controller (LAPIC)
10   - Rahul Tanwar <rtanwar@maxlinear.com>
13   Intel's Advanced Programmable Interrupt Controller (APIC) is a
14   family of interrupt controllers. The APIC is a split
17   (lapic) receives interrupts from the processor's interrupt pins,
26   This schema defines bindings for local APIC interrupt controller.
