This adds a SPI driver for the Microwire controller on OMAP1 chips. This
driver has been used in the Linux-OMAP tree for some time now, including
with some of those displays using standardized 9-bit commands followed by
data with 8-bit words.
Microwire only supports half duplex transfers, but that's all that most SPI
protocols need. When full duplex, or higher speeds, are needed there are
several other controllers that can be used on OMAP.
