Subject[PATCH v5 1/2] of: Documentation: Specify local APIC ID in "reg"
Set the "reg" property to the processor's local APIC ID.
Local APIC ID is assigned by hardware and may differ from CPU number.

-The reg property describes the CPU number. The lapic property points to
-the local APIC timer.
+A "cpu" node describes one logical processor (hardware thread).
+
+Required properties:
+
+- device_type
+ Device type, must be "cpu".
+
+- reg
+ Local APIC ID, a unique number assigned to each processor by
+ hardware. This ID is used to specify the destination of interrupt
+ messages with "physical" destination mode, including startup IPI.
