[PATCHv6 00/11] i2c: Relax mandatory I2C ID table passing

[Kieran Bingham <kieran@ksquared.org.uk>]

Version 6 of this patchset adds two new patches on top of the existing
submission to resolve the (final?) pending question from the previous
discussions during v5 [0]. Javier's tags are also collected here.

In particular, the remaining issue was that a user could provide a full
vendor prefixed string to the sysfs interface to instantiate an i2c
device. In version 5 of this submission this would not have matched
against a device driver as highlighted by the test patch provided by
Wolfram.

As such, in this series I have extended i2c_of_match_device_strip_vendor
so that it will also perform a search against a full compatible string
for the matching process. This was not done by the core OF framework as
the sysfs interface does not create an of_node to match against. If so
desired, this function could now be renamed to i2c_of_match_device_sysfs

Patch 11/11 of this series brings back Wolframs test case (correctly this
time) and also serves as a demonstration as to how to map the ID's when
matched against an of-style node. Note that this patch is *not* signed
off and not suitable for integration.
