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
- Reword commit text and subject
