This patchset includes the following fixes:

- Enable the target functionality in the interrupt handling routine 
  when the i2c transfer is about to finish.
- Correct the read/write operation procedure.
- Introduce a software flag to handle the bus error (BER) condition
  which is not caused by the i2c transfer.
- Modify timeout calculation.
- Assign the client address earlier logically.
- Use an i2c frequency table for the frequency parameters assignment.
- Coding style fix.

The NPCM I2C driver is tested on NPCM750 and NPCM845 evaluation boards.

Somehow your 6th patch becomes independent from the email thread.
(Initially I thought it was a separate fix)

Please, check what's going on with email settings on your side.

The series titled as "Bug fixes...", however I haven't noticed many
Fixes tags in it.

Understood. I'll remove the "Bug fixes" in the title in the next patch set.
