v2 (Stefan):
- Added clk framework support and dropped ad-hoc clock code
- Removed #ifdef's for Octeon vs OcteonTX/TX2 completely The differentiation is now made via driver data / compatible string
- Added device-tree bindings documentation
- Removed unused macro
RFC -> v1 (Stefan):
Separated this patch from the OcteonTX/TX2 RFC patch series into a single patch. This is useful, as the upcoming MIPS Octeon support will use this I2C driver.
Added MIPS Octeon II/III support (big endian). Rename driver and its function names from "octeontx" to "octeon" to better match all Octeon platforms.
Moved from union to defines / bitmasks as suggested by Simon. This makes the driver usage on little- and big-endian platforms much easier.
Enhanced Kconfig text
Removed all clock macros (use values from DT)
Removed long driver debug strings. This is only available when a debug version of this driver is built. The user / developer can lookup the descriptive error messages in the driver in this case anyway.
Removed static "last_id"
Dropped misc blank lines. Misc reformatting.
Dropped "!= 0"
Added missing function comments
Added missing strut comments
Changed comment style
Renames "result" to "ret"
Hex numbers uppercase
Minor other changes
