AC charger problem on OMAP4470

[ravirajns]

Hi All,

I am working customer board which based on OMAP4470 and twl6032 and facing below problems, Kernel version is 3.0.31 on Android 4.1.2

Problem 1:

  Whenever I connect AC charger to device continious interrupts come, due which device heats(OMAP always runs on 1.5 GHZ freq).

    I found that the  irq-373(twl_bci_fault) and irq  39 (TWL6030-PIH) are continious coming.

Problem 2:

While bootup AC and USB charger doesn't work.. once I remove and again connect charger after boot-up it works.

Please let me some suggestions to debug this issue.

Thanks and Regards,

Raviraj
