I have noticed my SABRE Lite board consumes around 100 mA @ 5V during suspend, with the Ethernet cable unplugged. I'm wondering if it is possible to connect the EN pins of the +2.5V and +1.2V (core voltage) regulators to GPIO pins on the i.MX6 and turn them off during suspend, then turn them back on during resume.

Hi Victhor
core voltage can not be disabled, they can be just lowered
(0.9V for VDD_ARM_IN ) during low power modes. One can check
IMX6DQCEC Table 6. Operating Ranges
Table 9. Stop Mode Current and Power Consumption
Best regards
igor
