Subject: [PATCH] ARM: kernel: document ARM CPUs clock-frequency property
Date: Wed, 19 Jun 2013 10:47:17 +0100	[thread overview]
Message-ID: <1371635237-22860-1-git-send-email-f.fainelli@gmail.com> (raw)

ARM CPU device tree nodes may contain an optional clock-frequency
property, when set, this property must contain the CPU frequency in Hz,
which is then used by the topology parsing code in
arch/arm/kernel/topology.c to infer the CPU capacity.

Document this property to avoid any possible confusion on the
clock-frequency unit.
