Subject: [PATCH v5 0/7] typec: mux: Introduce support for multiple USB 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.

Bjorn Andersson (7):
  device property: Add helper to match multiple connections
  device property: Use multi-connection matchers for single case
  usb: typec: mux: Check dev_set_name() return value
  usb: typec: mux: Introduce indirection
  usb: typec: mux: Allow multiple mux_devs per mux
  dt-bindings: usb: Add binding for fcs,fsa4480
  usb: typec: mux: Add On Semi fsa4480 driver
