Subject: [PATCH 1/5] ARM: sa1100: add platform functions to handle PWER settings
Date: Thu, 15 Jan 2015 13:09:30 +0300	[thread overview]
Message-ID: <1421316574-10022-1-git-send-email-dbaryshkov@gmail.com> (raw)

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.
