    Subject[PATCH v6 1/5] dt-bindings: media: Add Allwinner A10 CSI binding
    Date
    The Allwinner A10 CMOS Sensor Interface is a camera capture interface also
    used in later (A10s, A13, A20, R8 and GR8) SoCs.

    On some SoCs, like the A10, there's multiple instances of that controller,
    with one instance supporting more channels and having an ISP.
