[PATCH V3 4/7] dt-bindings: serial: fsl-lpuart: add i.MX7ULP support

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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.
