This series introduces bindings for anx7625/it6505 to register Type-C mode-switch in their output endpoints, and use data-lanes property to describe the pin connections. This series is not directly related to the built-in mux in anx7625, which automatically switches between the two orientations of a single Type-C connector. This series adds support of registering mode switches for two downstream devices, while we use orientation switches for two orientations of the Type-C connector. The first two patch modifies fwnode_graph_devcon_matches and cros_typec_init_ports to enable the registration of the switches. Patch 4~6 introduce the bindings for anx7625 and the corresponding driver modifications. Patch 7~9 add similar bindings and driver changes for it6505. v13: https://lore.kernel.org/all/20230303143350.815623-1-treapking@chromium.org/ v12: https://lore.kernel.org/all/20230221095054.1868277-1-treapking@chromium.org/ v11: https://lore.kernel.org/all/20230204133040.1236799-1-treapking@chromium.org/ v10: https://lore.kernel.org/all/20230112042104.4107253-1-treapking@chromium.org/ v9: https://lore.kernel.org/all/20230109084101.265664-1-treapking@chromium.org/ v8: https://lore.kernel.org/all/20230107102231.23682-1-treapking@chromium.org/ v7: https://lore.kernel.org/all/20230105132457.4125372-1-treapking@chromium.org/ v6: https://lore.kernel.org/all/20221124102056.393220-1-treapking@chromium.org/ v5: https://lore.kernel.org/linux-usb/20220622173605.1168416-1-pmalani@chromium.org/ Changes in v14: -
