Current sinking capability of iMX7 GPIOs when configured as Open Drain outputs

I was trying to find the current sinking abillity of GPIO pins of the iM7D SoC when configured as open drain output.


I could find the current sinking/sourcing capability for Push/Pull outputs but not for open drain outputs in the iMX7 datasheet:


A peripheral pin would be driving a CMOS Chip that is biased (supply voltage is at 5V). So I was thinking if it is possible to configure this pin(iMX7) as open drain and pull it up through a resistor to 5V to interface these devices.
