Merge tag 'spi-for-linus' of git://git.secretlab.ca/git/linux-2.6

Pull SPI updates from Grant Likely:
 "Primarily SPI device driver bug fixes, one removal of an old driver,
  and some new tegra support.  There is some core code change too, but
  all in all pretty small stuff.

  The new features to note are:
   - Common code for describing GPIO CS lines in the device tree
   - Remove the SPI_BUFSIZ limitation on spi_write_the_read()
   - core spi ensures bits_per_word is set correctly
   - SPARC can now use SPI"
