I knew it because I remembered when Shawn (from Freescale) tried to
mainline their serial driver and Wolfram (from Pengutronix) pointed out
that the IP is actually an amba pl011.
If you know that (or you see that CONFIG_SERIAL_AMBA_PL011=y in
arch/arm/configs/mxs_defconfig) it's just a matter of
$ grep \\.name drivers/tty/serial/amba-pl011.c
Best regards
Uwe
