PWRCTL2/BATEN2
USB port 2 power-on control for downstream power and battery charging enable. The
pin is used for control of the downstream power switch for port 2.
The value of the pin is sampled at the deassertion of reset to determine the value of
the battery charging support for Port 2 as indicated in the Battery Charging Support
Register:
0 = Battery charging not supported
1 = Battery charging supported
"
The PWRCTL_POL is left unconnected which results in active-high power enable (PWRCTL1, PWRCTL2,
PWRCTL3, and PWRCTL4) for a USB VBUS power switch.

please help me out of the use of pwrctl_pol and what is power_on control.
