This series adds a new typec class driver for the TUSB320xA family of
Type-C port controllers and a typec_mux class driver for the TS5USBA224
switch mux.

This series was bourne out of frustration with the existing extcon
driver for the TUSB320, which did not offer a convenient driver model
for the Audio Accessory mode muxing offered by the TS5USBA224. I found
the typec subsystem to be more suitable.

I have tested this on my i.MX8MM platform with USB OTG support and it
works as desired. However I am not very familiar with this part of the
kernel, so I welcome your critical feedback to this series. Thanks in
advance.
