    Subject[PATCH 5.16 0222/1039] tty: serial: uartlite: allow 64 bit address
    Date
    From: Lizhi Hou <lizhi.hou@xilinx.com>

    [ Upstream commit 3672fb65155530b5eea6225685c75329b6debec3 ]

    The base address of uartlite registers could be 64 bit address which is from
    device resource. When ulite_probe() calls ulite_assign(), this 64 bit
    address is casted to 32-bit. The fix is to replace "u32" type with
    "phys_addr_t" type for the base address in ulite_assign() argument list.

    Fixes: 8fa7b6100693 ("[POWERPC] Uartlite: Separate the bus binding from the driver proper")
