Subject: [PATCH 01/05 v2] gpio: rcar: Use lazy disable
Date: Wed, 20 Nov 2013 00:23:08 +0000 [thread overview]
Message-ID: <20131120002308.27342.34176.sendpatchset@w520> (raw)
In-Reply-To: <20131120002259.27342.35575.sendpatchset@w520>
From: Magnus Damm <damm@opensource.se>
Set the ->irq_enable() and ->irq_disable() methods to NULL
to enable lazy disable of interrupts. This by itself provides
some level of optimization, but is mainly enabled as ground
work for future Suspend-to-RAM wake up support.
