Does anyone know of a function in u-boot that can be called to power off the mx6 processor similar to the poweroff available in Linux?  Thanks.

Set TOP field in SNVS_LP Control (LPCR), which will trigger i.MX6 PMIC_ON_REQ with the Dump PMIC enabled.

Hello,

  If board hardware allows it - it is possible to use i.MX6 PMIC_ON_REQ signal

to switch off external PMIC.

 

How to control the PMIC_ON_REQ pin by SW without ON/OFF pin for i.MX6 

Regards,

Yuri.
