Yocto mx6dl PMIC_ON_REQ control on shutdown

Hi community,

 

    I need to look and work through the shutdown procedure of our imx6DL custom board that was based on sabresd and using PFUZE100 pmic.  

 

PMIC_ON_REQ line is connected to PMIC_PWRON

 

kernel version - 4.1.15

 

I'm trying to find the implementation of pm_power_off() function that is called on shutdown, and find a place where software toggles the PMIC_ON_REQ line, in case of a soft shutdown (issuing "$shutdown -h -P now")

 

We are using the device tree, and there is nothing that i could find in arch/arm/mach-imx

 

the rtc-snvs driver is disabled (CONFIG_POWER_RESET_IMX is not set)

 

Any tips ?

Thanks,

Stas
