Omap 3530 nSleep trigger?

Yavor Trifonov

Hi,

I've got an Omap 3530 with tps 65950. The SYS_OFF_MODE pin of the processor is connected to nSleep1 pin of the tps. Using Linux 2.6.32-rc7 I can see the mpu/core/neon powerdomains are going to off but the power scripts in the tps (sleep script) are not executed. What are the exact conditions for triggering SYS_OFF_MODE? If it is indeed triggered what can cause the tps to ignore the state of nSleep1 pin?

Thanks.
