I'm trying to figure out a high wakeup problem with a Palm Pre. The board is a TI OMAP 3430 board and using powertop I'm seeing a rather high number of interrupts on two I2C channels. My problem is more of a request for direction on where to look to debug this. Because the high interrupts seem to be keeping the system from being able to sleep. Also, I've read the same 'bug' on google android lists for phones that have the same board.
TI documentation lists two I2C connections on this board ( to connect to a GPS and to connect to a TWL5030 power board ), but powertop shows 3 I2C connections. Question: What tools or documentation lists how to use /sys/ and /proc/ to figure out what Linux sees on each i2c bus? - Mark Arrasmith
