Thanks for tracking that down. I see boot failures for arm:vexpress-a9
when trying to boot from mmc.

I dimly recall that I have seen this before. Ah yes ... commit 89a5e15bcba8
("gpio/mmc/of: Respect polarity in the device tree") fixes the above commit.
Can you give it a try ?

One may wonder though why the parsing code was backported in the first place.
It doesn't look like a bug fix to me.

Thanks,
Guenter
