DRA7xx USB1 DRVVBUS control


From Linux (6AL1.1, kernel 3.14), I have to disable/enable the USB 3.0 port during certain times.

Is there a standard means to do this (ioctl, sysfs, etc)?

I didn't think it was wise to configure the pin as a GPIO, and then use /sys/class/gpio/gpioX/value to control the pin, since the kernel's USB software would likely be the place where this is done, and I didn't want to break any state machines or other software that expects to be in control of the pin.

Thank you,

Matt Gessner
