    Subject[PATCH v3 0/3] dt-bindings: connector: usb: provide bindings for altmodes
    Date
    In some cases we need a way to specify USB-C AltModes that can be
    supportd on the particular USB-C connector. For example, x86 INT33FE
    driver does this by populating fwnode properties internally. For the
    Qualcomm Robotics RB5 platform (and several similar devices which use
    Qualcomm PMIC TCPM) we have to put this information to the DT.

    Provide the DT bindings for this kind of information and while we are at
    it, change svid property to be 16-bit unsigned integer instead of a
    simple u32.

    NOTE: usage of u16 is not compatible with the recenty extended
    qcom/qrb5165-rb5.dts DT file. I'm looking for the guidance from DT and
    USB maintainers whether to retain u32 usage or it's better to switch to
    u16.

    Changes since v2:
    - Inlined altmode definitions instead of having them under $defs (Rob)
    - Explicity list permitted AltMode names (currenty only displayport is
    allowed) (Rob)

    Changes since v1:
    - Added type:object and fixed 'description' string in the altmodes-list
    definition.
