OMAP-L138 Power States

Other Parts Discussed in Thread: OMAP-L138

Hi,

I am a litte bit confused about the powerstates of the OMAP-L138. I found these 2 documents:

1.http://processors.wiki.ti.com/index.php/OMAP-L1_Linux_Drivers_Usage#Power_Management

2.http://processors.wiki.ti.com/index.php/Startup_shutdown_and_power_management.

As far as I understand this the ARM Idle state correspods to C0 and the standby somehow corresponds to C1 just with the paripherals still powerd. Is this correct?

I am currently using the kernel from the DaVinci-PSP-SDK-03.20.00.11. Is it possible to enter standby with this kernel? I can enter deep sleep with suspend to ram as desribed in the first document but AFAIK I can only wake up from RTC Timer from DeepSleep but I want to wake up from other interrupts too like ethernet or from a touch display. Is this possible?
