Subject: [PATCH v6 1/2] of: Documentation: Specify local APIC ID in "reg"
Message-ID: <c5eb2fd010855d187007859e7a332c866fbd41ec.1520974793.git.ivan.gorinov@intel.com>

Precedence: bulk

Use the "reg" property to specify 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, the unique number assigned to each processor by
