Subject: [PATCH v3 8/9] arm,arm64,drivers: move externs in a new header file
Date: Mon, 27 Mar 2017 14:18:24 +0100	[thread overview]
Message-ID: <20170327131825.32134-9-juri.lelli@arm.com> (raw)
In-Reply-To: <20170327131825.32134-1-juri.lelli@arm.com>

Create a new header file (include/linux/arch_topology.h) and put there
declarations of interfaces used by arm, arm64 and drivers code.
