Subject: [PATCH v3 3/8] arm64: add io{read,write}64be accessors
Date: Thu, 19 May 2016 18:11:04 +0300 [thread overview]
Message-ID: <1463670664-2856-1-git-send-email-horia.geanta@nxp.com> (raw)
In-Reply-To: <1463670405-1059-1-git-send-email-horia.geanta@nxp.com>
This will allow device drivers to consistently use io{read,write}XXbe
also for 64-bit accesses.
