Subject: [PATCH v2 8/9] arm,arm64,drivers: move externs in a new header file
Date: Thu, 9 Feb 2017 09:25:24 +0000 [thread overview]
Message-ID: <20170209092525.6654-9-juri.lelli@arm.com> (raw)
In-Reply-To: <20170209092525.6654-1-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.
