[PATCH V2 4/6] tty: serial: lpuart: add imx7ulp support

2017-05-15 Thread Dong Aisheng
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 that it has four extra registers (verid, param, global, pincfg) located at the beginning
