Is Haibo the author of this patch? If so, his name should appear in
the From field.

Please avoid using 0x80000000 and use the real IOMUX value instead.

I made this patch based on NXP kernel tree, Haibo is the original author of this
feature, but the original patch can NOT be applied directly, I have to refine the patch
to meet the upstream requirement, so I added him as another signed-off tag,
to avoid confuse, I can remove this sign-off in next patch version. Same story
for other patches in this series.
