This patch series adds support to show and change the bus frequency
via sysfs, by exposing files to show the minimum, maximum and current
frequency as well as allowing the frequency to be changed. This allows
the user to view or change the bus frequency on a per bus level.

Changes since v3:

* use DEVICE_ATTR_RO and make i2c_adapter_visible_attr static

* implement sysfs bus frequency support for the diolan u2c bus

Octavian Purdila (4):
i2c: document the existing i2c sysfs ABI
i2c: document struct i2c_adapter
i2c: show and change bus frequency via sysfs
i2c: i2c-diolan-u2c: sysfs bus frequency support
