    Subject[PATCH v2 1/2] Revert "USB: serial: ch341: add new Product ID for CH341A"
    Date
    From: frank zago <frank@zago.net>

    The 0x5512 USB PID is for the I2C/GPIO/SPI interfaces. UART is still
    present but only the TX and RX pins are available; DTS, DTR, ... are
    used for other things. Remove the PID, and let a I2C driver bind to
    it.

    Existing CH341 boards usually have physical jumpers to switch between
    the 3 modes.

    This reverts commit 46ee4abb10a07bd8f8ce910ee6b4ae6a947d7f63.
