Dear Minkyu Kang, The reason I didn't provide the last patch to use the hardware I2C is that on Trats board a software I2C is used to communicate with Fuel Gage. Unfortunately in u-boot soft_i2c and hardware I2C cannot be used at the same time. The patchset was tested on Trats board and it worked correctly.
I could provide the last patch to use hardware I2C on Trats board for test purposes and prove that it can be used on other boards.
