commit 0caf34350a25907515d929a9c77b9b206aac6d1e upstream. The I2C2 pins are already used and the following errors are seen: imx27-pinctrl 10015000.iomuxc: pin MX27_PAD_I2C2_SDA already requested by 10012000.i2c; cannot claim for 1001d000.i2c imx27-pinctrl 10015000.iomuxc: pin-69 (1001d000.i2c) status -22 imx27-pinctrl 10015000.iomuxc: could not request pin 69 (MX27_PAD_I2C2_SDA) from group i2c2grp on device 10015000.iomuxc imx-i2c 1001d000.i2c: Error applying setting, reverse things back imx-i2c: probe of 1001d000.i2c failed with error -22 Fix it by adding the correct I2C1 IOMUX entries for the pinctrl_i2c1 group.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
