From mboxrd@z Thu Jan 1 00:00:00 1970 From: lee.jones@linaro.org (Lee Jones) Date: Thu, 23 Aug 2012 16:01:25 +0100 Subject: [PATCH 1/3] ARM: ux500: Add i2c configurations to the Device Tree for DB8500 based devices Message-ID: <1345734087-21803-1-git-send-email-lee.jones@linaro.org> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org Since initial support was provided for the Nomadik I2C driver, it has been converted to an AMBA device. AMBA devices are probed in a slightly different way to other devices, so we have to identify them using an "arm,primecell" compatible string. As well as doing just that, this patch specifies which regulators the controller should use and requests a clock-speed. The latter is provided as more of an example, as it's the same as the recently changed default configuration.
