From: Tyrone Ting <kfting@xxxxxxxxxxx> 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.
