[PATCH 07/22] ARM: omap1: move perseus spi pinconf to board file

[PATCH 07/22] ARM: omap1: move perseus spi pinconf to board file

[Arnd Bergmann]

The driver has always had a FIXME about this, and it seems
like this trivial code move avoids a mach header inclusion,
so just do it.

With that out of the way, and the header file inclusions
changed to global files, the driver can also be compile-tested
on other platforms.

This appears to be part of a series but I've no cover letter or anything
else from it.  What's the story for dependencies and merging?

Sorry for missing you on the cover letter. The patch is part of a series
to make omap1 part of ARCH_MULTIPLATFORM. I'd like to merge the entire
series through the arm-soc tree to avoid dependencies:
