Dear Freescale Support Team,
We are working on the Power management Module on i.MX6Q Based SabreSDP Platform with B5 Revision and the Processor Revision is 1.2(i.e AC)
We would like to know about the ARM Power off sequence in i.MX6q and any one has the procedure to Enter in to the ARM Power off state please share.
And i would like to know any other module dependency with ARM Power off . What is the power consumption will reduce if ARM Power off performed in the SabreSDP Platform.
Any other documentation for suspend and resume what is the exact procedure. How to make sure ARM is in Power OFF mode.
Best Regards,
Cader.

The mentioned app notes relate to Linux BSP :

Please use Linux documentation for information about source files, responsible
for power saving modes.

In particular, please look at Chapter 16 "Low-level Power Management (PM) Driver"
of "Linux_6DQ_RM_L3.0.35_1.1.0.pdf".
Also the SDK contains examples.
Please look at Chapter 24 (Configuring the Power Modes) of "iMX6_Firmware_Guide.pdf".

Please look at section 5 (Use case configuration and usage guidelines) of app note AN4576 (i.MX 6DualLite Power Consumption Measurement), in particular, for Deep-Sleep mode :
echo mem > /sys/power/state
