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