[PATCH v4 00/14] i2c-octeon and i2c-thunderx drivers

[Jan Glauber <jglauber@cavium.com>]

This series for the Octeon i2c driver is an attempt to upstream some
bug fixes and features that accumulated for some time.

On top of the Octeon changes a i2c driver for the ThunderX SOC is
added which uses the same functional block as the Octeon driver.

Patches #1-2 are cleanups.
Patches #3-10 are forward-ports of Octeon features and bugfixes.
Patch #11-12 prepare for the driver split
Patches #13-14 add the ThunderX driver.

Patches are on top of 4.5 + i2c-octeon-kerneldoc-patch and were
tested on OCTEON, OCTEON-78 and ThunderX.

Changes to v3:
- added more functionality flags for SMBUS
- removed both module parameters
- make xfer return also other errors than EGAIN
- return EPROTO on invalid SMBUS block length
- use devm_ioremap_resource
- added rename-only patch
- removed kerneldoc patch from series
- improved defines

Changes to v2:
- Split clenaup patch into several patches
- Strictly moved functional changes to later patches
- Fixed do-while checkpatch errors
- Moved defines to the patches that use them
- Use BIT_ULL macro
- Split ThunderX patch into 2 patches

Changes to v1:
- Fixed compile error on x86_64
- Disabled thunderx driver on MIPS
- Re-ordered some thunderx probe functions for readability
- Fix missing of_irq.h and i2c-smbus.h includes
- Use IS_ENABLED for CONFIG options
