[PATCH] SPI controller driver for OMAP Microwire
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.
