This series introduces a binding for Type-C data lane switches. These
control the routing and operating modes of USB Type-C data lanes based
on the PD messaging from the Type-C port driver regarding connected
peripherals.
The first patch introduces a change to the Type-C mux class mode-switch
matching code, while the second adds a config guard to a Type-C header.
The next couple of patches introduce the new "typec-switch" binding as
well as one user of it (the ANX7625 drm bridge).
The remaining patches add functionality to the anx7625 driver to
register the mode-switches, as well as program its crosspoint
switch depending on which Type-C port has a DisplayPort (DP) peripheral
connected to it.
