[maverick][PATCH] UBUNTU: SAUCE: Load SysLink modules on start-up on OMAP4 devices

[Lee Jones]

This patch will become part of the Syslink driver code and is not due to go upstream until
the remaining Syslink code is ready to do so, hence SAUCE. It is believed that the next 
version TI release will be upstreamable.

This patch registers the SysLink driver-set as a platform device.
During the registration process a uevent will be fired, allowing
udev to pick it up and load the necessary loadable modules.

The following changes since commit 05cd276ae6bfe20745244f2285fab2b3d40ca1e3:
  Tim Gardner (1):
