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".
