The Prism54 SPI driver hardcodes GPIO numbers and expects users to
pass them as module parameters, apparently a relic from its life as a
staging driver. This works because there is only one user, the Nokia
N8x0 tablet.

Convert this to the gpio descriptor interface and move the gpio
line information into devicetree to improve this and simplify the
code at the same time.

Yes, this is definitely the right idea/way. From what I remember, Kalle
Valo was partially involved in p54spi/stlc45xx. The details are very fuzzy.
So,  I could be totally wrong. From what I remember Kalle was working
for Nokia (or as a contractor for Nokia?) at the time.

I wrote stlc45xx driver as part of my thesis when working for Nokia and
I think then someone wrote p54spi after that. Oh man, this was a long
time ago so hard to remember :)
