DM3730 suspend issue

Other Parts Discussed in Thread: TPS65072, WL1271

Hi All,

We are using VAR-SOM-OM37 SOM(DM3730 + TPS65930) from variscite with kernel version 2.6.37 and Gingerbread android OS.

I don't know but my platform is not going to suspend state in the first attempt most of the time. After trying one or two times, it is entering properly.

I am pasting the log here.

In very rare cases, it is not at all entering into suspend state.

Can anybody tell me the reasons by analyzing logs?

Thanks,

Naresh

    Hi Naresh,

    [ 356.349731] PM: Some devices failed to suspend

    that the attempt to writing to the touchscreen (atmel_mxt_ts) registers fails. After this fail the touchscreen doesn't receive a command for sleeping and it continue to be in active state. Therefore the whole system rejects the attempt for going to sleep.

    I suggest you to investigate the problem with communication with the touchscreen but I only can guess for the reason for the fail. It is possible to have some issue with the communication via i2c or the touchscreen to be in some state which does not allow sleeping - at this moment to sends information for events for example.
