[PATCH v2 0/7] usb: typec: Introduce typec-switch binding

[Prashant Malani <pmalani@chromium.org>]

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.

v1: https://lore.kernel.org/linux-usb/20220607190131.1647511-1-pmalani@chromium.org/

Changes since v1:
- Fixed function signature error in "else case" of typec_mux.h
- typec-switch.yaml: Fixed indentation, compatible, and node names in examples.
- anx7625.yaml:
    + Introduced patternProperties for "switch" children (suggested by Krzysztof Kozlowski).
    + Added unevaluatedProperties descriptor (suggested by Krzysztof Kozlowski).
    + Added "address-cells" and "size-cells" properties to "switches".
