[PATCH v4 0/6] i2c: npcm: read/write operation, checkpatch

[warp5tw at gmail.com]

From: Tyrone Ting <kfting at nuvoton.com>

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.
