    HISI LPC: Add ACPI UART support · adf3457b
    John Garry authored
    On the Huawei D03 development board the system UART is
    the UART connected on the LPC bus.
    
    The profile for the device driver required for this HW
    is as follows:
     - platform driver
     - 16550
     - ACPI support
     - polling mode support
     - IO space support
    
    In principle we should use the PNP driver (8250_dw.c) for
    8250-devices with ACPI FW. However since this driver does
    not support PNP devices, and modifying the PNP core code
    to support it is not worth the effort, use the generic
    8250 isa driver.
    
    For this, we setup the pdev platform data for the serial
    8250 port.
