Subject: [PATCH 03/10] ARM: shmobile: r8a7791 IRQC platform device support
Date: Tue, 01 Oct 2013 08:12:19 +0000 [thread overview]
Message-ID: <20131001081219.4136.26850.sendpatchset@w520> (raw)
In-Reply-To: <20131001081143.4136.46925.sendpatchset@w520>
From: Magnus Damm <damm@opensource.se>
Add a platform device for the r8a7791 IRQC hardware
driving IRQ pins IRQ0 to IRQ9. The Linux interrupt
number is statically assigned to allow board code
written in C to make use of static interrupt numbers.
Signed-off-by: Magnus Damm <damm@opensource.se>
