linux-stable.git/include/linux/of_i2c.h, branch master Linux kernel stable tree i2c: move OF helpers into the core 2013-08-23T08:22:20+00:00 Wolfram Sang wsa@the-dreams.de 2013-07-11T11:56:15+00:00 687b81d083c082bc1e853032e3a2a54f8c251d27 I2C of helpers used to live in of_i2c.c but experience (from SPI) shows that it is much cleaner to have this in the core. This also removes a circular dependency between the helpers and the core, and so we can finally register child nodes in the core instead of doing this manually in each driver. So, fix the drivers and documentation, too. Signed-off-by: Wolfram Sang <wsa@the-dreams.de>

drivers/of: Add the of_find_i2c_device_by_node function. 2009-01-09T22:49:06+00:00 Jon Smirl jonsmirl@gmail.com 2009-01-09T22:49:06+00:00 2526c151c31358aec66b63921dd712bbec5ee0cb The of_find_i2c_device_by_node function allows you to follow a reference in the device tree to an i2c device node and then locate the linux device instantiated by the device tree. Example use: an I2S bus driver finding the i2c_device instance for a codec described by a device tree node. This was waiting for Anton's i2c patches that were just added.
