Subject: [PATCH v3 04/10] arm: sa1100: use new functions that hide PWER access
Date: Sun, 15 Dec 2013 08:28:11 +0400	[thread overview]
Message-ID: <1387081697-21841-5-git-send-email-dbaryshkov@gmail.com> (raw)
In-Reply-To: <1387081697-21841-1-git-send-email-dbaryshkov@gmail.com>

In order to continue cleaning up of the sa11x0 IRQ driver, split away
PWER setting. Now irq driver asks core to enable either irq wake event
or to enable GPIO wake event, instead of accessing PWER directly.
