Subject: [PATCH 01/02] irqchip: renesas-irqc: Use lazy disable
Date: Wed, 04 Dec 2013 12:05:46 +0000 [thread overview]
Message-ID: <20131204120546.29642.15772.sendpatchset@w520> (raw)
In-Reply-To: <20131204120537.29642.942.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.
