The original semantics of UPIO_MEM did not include the notion of bitness and endianness; different drivers used UPIO_MEM to refer to their original mmio bitness/endianness. For example, for the 8250 driver this is 8-bit LE but for the amba-pl011 driver this is 16-bit LE. Since UPIO_* values are userspace ABI via TIOCGSERIAL/TIOCSSERIAL ioctls, the original meaning of UPIIO_MEM must remain as it was: the original mmio stride/width/endianness of the driver.
