From 687b81d083c082bc1e853032e3a2a54f8c251d27 Mon Sep 17 00:00:00 2001
From: Wolfram Sang <wsa@the-dreams.de>

Subject: [PATCH] i2c: move OF helpers into the core
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.
