Good catch!

Similarly to a recently reported bug in io_ti, a malicious USB device
could set port_number to -3 and we would underflow the port array in the
interrupt completion handler.
As these devices only have one or two ports, fix this by making sure we
only consider the seventh bit when determining the

TI AM335x CPPI41 module uses a single register bit for CPPI interrupts in
both musb controllers. So disabling the CPPI irq in one musb driver breaks
the other musb module.
Since musb is already disabled before tearing down dma controller in
musb_remove(), it is safe to not disable CPPI irq in

Some hardware implementations require to configure pins differently
according to the USB role (host/device), this can be an update of the
pins routing or a simple GPIO value change.
This patch introduces new optional "host" and "device" pinctrls.
If these pinctrls are defined by the device, they
Phy power on/off cycle can happen several times during device life.
We then need to balance the extcon notifier registration accordingly.

Add compatibility for extcon-usb-gpio which can handle more
than one cable per instance, allowing coherency of USB cable
states (USB/USB-HOST). These states can be generated from ID
or/and VBUS pins.
In case only one extcon device is associated to the USB device,

At OTG work running time, it's possible that several events need to be
addressed (e.g. ID and VBUS events). The current implementation handles
only one event at a time which leads to ignoring the other one. Fix it.
