I need to enable power saving mode on my i.MX6 Solo based board. The board used same configuration of sabrelite with additional PMIC (PF0100 as pmic).
All I need is to switch the device to STANDBY mode based on a GPIO interrupt (looks like mem mode is not supported by the kernel)
These are the power state modes supported in my board.
root@imx6qsabrelite:/# cat /sys/power/state
freeze standby mem
I am also able to make switch board to STOP mode by below command.
root@imx6qsabrelite:~# echo standby > /sys/power/state
PM: Syncing filesystems ... done.
Freezing user space processes ... (elapsed 0.01 seconds) done.
PM: Calling sched_clock_suspend+0x0/0x2c
PM: Calling fw_suspend+0x0/0x24
PM: Calling cpufreq_bp_suspend+0x0/0xc4
PM: Calling cpu_pm_suspend+0x0/0x20
How do I configure a GPIO as the wake up source?
Appreciate your pointers...
