f2422fe437 dt-bindings: serial: fsl-lpuart: add i.MX7ULP support 
The lpuart of imx7ulp is basically the same as ls1021a. It's also
32 bit width register, but unlike ls1021a, it's little endian.
Besides that, imx7ulp lpuart has a minor different register layout
from ls1021a.

6b9c1fa25a serial: unify serial bindings into a single dir 
Move all bindings in bindings/tty/serial into bindings/serial so we only
have one place dir with serial/uart related bindings in it.
