Hi ,
We have ported Android JB 4.2.5p1 on our custom board. Our board has Bq27520 battery chip-set. We get i2c timeout error when we try to include the battery driver from 4.2.2p1 release as shown below :
omap_i2c omap_i2c.2: timeout waiting for bus ready
[ 32.926940] power_supply bq27500-0: driver failed to report `temp' property: 4294966918

However when i use the Battery driver from ics, there seems to be no problem.
Any help would be greatly appreciated.
I have attached the entire log for your reference.
Thank You
