Richard Purdie 50a5de4482 [PATCH] SharpSL: Abstract c7x0 specifics from Corgi SSP
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.
