From mboxrd@z Thu Jan 1 00:00:00 1970 From: andy@warmcat.com (Andy Green) Date: Tue, 15 Mar 2011 19:56:18 +0000 Subject: [PATCH 3 04/18] I2C: OMAP2+: hwmod data: Tag all OMAP2+ hwmod definitions with I2C IP revision In-Reply-To: <20110315195147.30000.86184.stgit@otae.warmcat.com> References: <20110315195147.30000.86184.stgit@otae.warmcat.com> Message-ID: <20110315195618.30000.53926.stgit@otae.warmcat.com> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org Since we cannot trust (or even reliably find) the OMAP I2C peripheral unit's own revision register, we must inform the OMAP I2C driver of which IP version it is running on. We do this by tagging the omap_hwmod_class for I2C on all the OMAP2+ platform / cpu specific hwmod init and passing it up to the driver (next patches).
