[PATCH v9 0/8] i2c-octeon and i2c-thunderx driver

[Jan Glauber]

Hi Wolfram,

this update adds ACPI support for the clock-frequency setting in the
thunderx driver. For SMBUS alert support it is currently unclear how
it will look like in ACPI so I left that unimplemented.

Patch #5 - #7 are (final) cleanup patches.

Patches are on-top of next-20160512.

Changes to v8:
- Use device property for clock-frequency setting in thunderx,
  get rid of of_find_node_by_name
- Simplify adap.name by using device name
- SMBUS ACPI handling
- Re-phrase SMBUS error/not-specified message

Changes to v7:
- Sort include files also in octeon-core.c
- Add cleanup bool patch (left-over from v7)
- Dropped read-write function shuffle patch

Changes to v6:
- Fixed read_int kerneldoc
- Removed udelay after write-int in recovery
- Killed retries in recovery, use EAGAIN
- Disable SMBUS QUICK and remove unneeded length check
- Spell out enable/disable
- Switch to wait_event_timeout
- Removed superfluous status check in HLC write
- Optimize wait-queue also for HLC
- Use readq/writeq instead of __raw_* in some places
- Add STAT_IDLE to status check (valid after a write)

Changes to v5:
- Switch to i2c recovery framework
- Clean-up register access, introduce new helper functions
- Fixed ready bit check in combined write
- Fixed IFLG clear in hlc_enable
- Removed complicated last phase logic, not needed when we send
  START for every message part

Changes to v4:
- Splitted the High-Level Controller patch into several patches
- Reworded some commit messages

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

Thanks,
Jan
