Subject: [PATCH v2 0/6] typec: mux: Introduce support for multiple TypeC muxes

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.

Included in the series is a the new FSA4480 driver. This is done to deal with
the renaming of the driver-side typec_mux -> typec_mux_dev.

Changes since v1:
- Omitted QMP changes from this series, as the muxing implementation needs a
  little bit more debugging.

Bjorn Andersson (6):
  device property: Helper to match multiple connections
  device property: Use multi-connection matchers for single case
  typec: mux: Introduce indirection
  typec: mux: Allow multiple mux_devs per mux
  dt-bindings: usb: Add binding for fcs,fsa4480
  usb: typec: mux: Add On Semi fsa4480 driver
