On imx8m it is more correct to read the data register than the pad

In output mode the pad status register does not contain the value

In input mode the DR will contain the same value as the PSR when the
pad
mode is GPIO.
If the pad mode is not GPIO and the pin is an input then 0 is always
returned.
Have you tried setting the SION bit of the pad?
I have tried it with the SION bit set but I thought it would be better
if the dts would match the linux dts and return the same result.
