In addition to what Andrew said, you need to look at how you're sending
patches - this patch looks like it has been whitespace damaged, which
means it can't be applied.

Thanks for the feedback. There's 2 reserved ranges in that register
with no further descriptions available.
If naming the bit offset after the field range is OK, I will make edit
and submit a V2 though send-email.
