From: Dirk Brandewie <dirk.brandewie@xxxxxxxxx>

This patch set reworks i2c-designware.c to enable supporting multiple
instances of the driver in the system and adds support for Designware
I2C IP cores behind PCI devices.

Previous discussion thread:

Changes since V4:
rebased onto v3.1-rc9.
cleanup of whitespace errors
Fix warning from PCI core during suspend/resume.
Dropped patch removing i2c-intel-mid.c

Changes since V3:
commits 330d1c^..5c7d3e from linux-next rebased onto v3.0-rc2

Changes since V2:
Fixed bug that kept PCI driver from compiling :-(

PCI Runtime power mangement code changed to remove warning at probe
time and remove device.

Fix checking of component version on big endian machine to work

Changes since V1 of the patch set:

Patches 1-3 are now Jean-Hugues Deschenes patches unmodified from

Patch 4 moves the version checking introduced in Jean's code to the
core init function.

Patch 5 splits i2c-designware.c into IP core and bus specific files.

Patch 6-9 rework i2c-designware-core.c and i2c-designware-platdrv.c to
add the ability to support multiple instances of the driver.

Patch 10 Finishes moving all register access and associated offset and
bit definitions into the core.

Patch 11 Adds support for designware I2C IP cores behind PCI
devices on the Moorestown and Medfield platforms. removed change to
authors name.

Patch 12 Adds runtime power management to the PCI driver.

Patch 13 Fixs a warning from the PCI core during suspend/resume.
