 SPI device driver bug fixes branch for the v3.8 merge window. Most of
 this is bug fixes to the core code and the sh-hspi and s3c64xx device
 drivers.
 
 There is also a patch here to add DT support to the Atmel driver. This
 one should have been in the first round, but I missed it. It's a low
 risk change contained within a single driver and the Atmel maintainer
 has requested it.
