From mboxrd@z Thu Jan 1 00:00:00 1970 From: Andreas Larsson Subject: [PATCH v3 0/2] i2c: i2c-ocores: Add support for sparc, custom set and get functions, and the GRLIB port of the controller Date: Tue, 13 Nov 2012 20:25:25 +0100 Message-ID: <1352834727-16368-1-git-send-email-andreas@gaisler.com> Return-path: Sender: linux-kernel-owner@vger.kernel.org To: Wolfram Sang , Ben Dooks , Peter Korsgaard Cc: linux-i2c@vger.kernel.org, Grant Likely , devicetree-discuss@lists.ozlabs.org, linux-kernel@vger.kernel.org, software@gaisler.com List-Id: linux-i2c@vger.kernel.org On sparc, irqs are not present as an IORESOURCE in the struct platform_device representation. By using platform_get_irq instead of platform_get_resource the driver works for sparc. The GRLIB port of the ocores i2c controller needs custom getreg and setreg functions to allow for big endian register access and to deal with the fact that the PRELOW and PREHIGH registers have been merged into one register. Signed-off-by: Andreas Larsson Changes since v2: - Return error from platform_get_irq on error - Trigger usage of the grlib specific functions on compatible property instead of name Andreas Larsson (2): i2c: i2c-ocores: Add irq support for sparc i2c: i2c-ocores: Add support for the GRLIB port of the controller and custom getreg and setreg functions drivers/i2c/busses/i2c-ocores.c | 66 ++++++++++++++++++++++++++++++++++---- 1 files changed, 59 insertions(+), 7 deletions(-)
