    Subject[PATCH v11 0/9] Register Type-C mode-switch in DP bridge endpoints
    Date

    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.

    - Removed DT property validation in it6505 driver
    - Rebased to drm-misc-next
    - Fixed indentations in bindings patches
    - Added a new patch to fix indentations in Kconfig

    Changes in v6:
    - Changed it6505_typec_mux_set callback function to accommodate with
    the latest drm-misc patches
    - Changed the driver implementation to accommodate with the new binding
    - Dropped typec-switch binding and use endpoints and data-lanes properties
    to describe the pin connections
    - Added new patches (patch 1,2,4) to fix probing issues
    - Changed the bindings of it6505/anx7625 and modified the drivers
    accordingly
