Sharp's newer range of Zaurus clamshell handhelds, the cxx00's are similar to the c7x0 series yet different. This patch series abstracts the differences and generates a set of common drivers that support both series of devices. It then adds machine support for Spitz (SL-C3000) and Borzoi (SL-C3100). Hooks for Akita (SL-C1000) differences are also added. The I2C driver for its IO expander is the only missing piece. This patch: Separate out the Sharp Zaurus c7x0 series specific code from corgi_ssp.c so that other models such as the cxx00's can share it. Create sharpsl.h which will be used to abstract machine/model specifics. This enables the driver to be used by the Zaurus cxx00 series.
