Hi list,
Physik Instrumente uses an FTDI chip for their hardware. I found yet another
new hardware type from them which is not in the FTDI list. Here is a patch for
it.

TCPCI stands for typec port controller interface, its implementation
has full typec port control with power delivery support, it's a
standard i2c slave with GPIO input as irq interface, detail see spec
"Universal Serial Bus Type-C Port Controller Interface Specification
Revision 1.0, Version 1.1"
This patch adds 3 APIs to get the typec port power and data type,
and preferred power role by its name string.

This allows dual-role ports to be reported as having gadget mode by the
musb_has_gadget helper. This is required to enable MUSB at all with MUSB
glue layers that set the port mode to MUSB_PORT_MODE_DUAL_ROLE at init.
Most notably, this allows calling musb_start when needed in the virtual

I still haven't managed to find a gcc that reproduces this, so I
probably need to get the exact same distro you are using installed
somewhere :-(

better check it's return value to avoid a NULL pointer dereference

The Aspeed BMC SoCs support a "virtual hub" function. It provides some

This driver adds support for the full functionality, emulating the

This driver handles the reset control in a common manner; deassert
resets before use, assert them after use. There is no good reason
why it should be exclusive.
Also, use devm_ for clean-up.
