From mboxrd@z Thu Jan 1 00:00:00 1970 From: Andreas Larsson Subject: [PATCH 1/2] i2c: i2c-ocores: Add irq support for sparc Date: Tue, 23 Oct 2012 17:03:56 +0200 Message-ID: <1351004637-11049-2-git-send-email-andreas@gaisler.com> References: <1351004637-11049-1-git-send-email-andreas@gaisler.com> Return-path: In-Reply-To: <1351004637-11049-1-git-send-email-andreas-FkzTOoA/JUlBDgjK7y7TUQ@public.gmane.org> Sender: linux-i2c-owner-u79uwXL29TY76Z2rM5mHXA@public.gmane.org To: linux-i2c-u79uwXL29TY76Z2rM5mHXA@public.gmane.org, Peter Korsgaard Cc: Jean Delvare , Ben Dooks , Wolfram Sang , Grant Likely , Rob Herring , linux-kernel-u79uwXL29TY76Z2rM5mHXA@public.gmane.org, devicetree-discuss-uLR06cmDAlY/bJ5BZ2RsiQ@public.gmane.org, software-FkzTOoA/JUlBDgjK7y7TUQ@public.gmane.org List-Id: devicetree@vger.kernel.org There are no platform resources of type IORESOURCE_IRQ on sparc, so the irq number is acquired in a different manner for sparc. The general case uses platform_get_irq, that internally still uses platform_get_resource.
