Subject: [PATCH v8 12/12] ARM: shmobile: Convert file to use cntvoff
Date: Tue, 1 May 2018 14:31:31 +0200 [thread overview]
Message-ID: <20180501123131.7738-13-mylene.josserand@bootlin.com> (raw)
In-Reply-To: <20180501123131.7738-1-mylene.josserand@bootlin.com>
Now that a common function is available for CNTVOFF's
initialization, let's convert shmobile-apmu code to use
this function.
