Subject: [PATCH 03/03] gpio: em: Use lazy disable and mask on suspend
Date: Wed, 13 Nov 2013 22:59:55 +0000 [thread overview]
Message-ID: <20131113225955.21449.34737.sendpatchset@w520> (raw)
In-Reply-To: <20131113225927.21449.78044.sendpatchset@w520>
From: Magnus Damm <damm@opensource.se>
Set the ->irq_enable() and ->irq_disable() methods to NULL
to enable lazy disable of interrupts. Also extend the code
to set IRQCHIP_MASK_ON_SUSPEND which tells the core that
only IRQs marked as wakeups need to stay enabled during
Suspend-to-RAM.
Tested on the KZM9D board with GPIO-keys.
