    Subject[PATCH RFC 0/4] Driver for Apple Z2 touchscreens.
    Date
    Hi.

    This series adds support for Apple touchscreens using the Z2 protocol.
    Those are used as the primary touchscreen on mobile Apple devices, and for the
    touchbar on laptops using the M-series chips. (T1/T2 laptops have a coprocessor
    in charge of speaking Z2 to the touchbar).

    Sending this as a RFC for now, since this series requires the SPI controller
    support which is not upstream yet:
