This series introduces a level of indirection between the controller's view of a typec_mux/switch and the implementation and then expands that to support multiple drivers. This is needed in order to support devices such as the Qualcomm Snapdragon 888 HDK, which does muxing and orientation handling in the QMP (USB+DP) PHY and SBU muxing in the external FSA4480 chip. Additionally integration of typec mux and switch in the QMP PHY is included in the series, as is the new FSA4480 driver. This is done to deal with the renaming of the driver-side typec_mux -> typec_mux_dev.

But what I can do is test this on an x86 device using a pi3usb30532 mux for USB super-speed and DP-alt-mode muxing / orientation switching.
Thanks Hans, that would be much appreciated. I realize that I failed to mention that I don't have this hardware, so I've not been able to test it myself.
I'm going to wait a bit with doing that till this has had some reviews and possibly also some newer versions because of those reviews. If you haven't received a Tested-by from me when this looks like it is ready for merging please ping me.
Will ping you when appropriate. Thanks, Bjorn
