Subject: [PATCH v3 03/10] ARM: sa1100: add platform functions to handle PWER settings
Date: Sun, 15 Dec 2013 08:28:10 +0400	[thread overview]
Message-ID: <1387081697-21841-4-git-send-email-dbaryshkov@gmail.com> (raw)
In-Reply-To: <1387081697-21841-1-git-send-email-dbaryshkov@gmail.com>

PWER settings logically belongs neither to GPIO nor to system IRQ code.
Add special functions to handle PWER (for GPIO and for system IRQs)
from platform code.
