Subject: [PATCH] ARM: topology: Make it clear that all CPUs need to be described
Date: Thu, 20 Mar 2014 12:59:34 +0000	[thread overview]
Message-ID: <1395320374-29576-1-git-send-email-broonie@kernel.org> (raw)

From: Mark Brown <broonie-QSEj5FYQhm4dnm+yROfE0A@public.gmane.org>

The ARMv8 code will reject topologies that omit some CPUs (and it's not
clear that it's ever sensible to do so). Update the binding document to
make this clear.
