[PATCH] ppc32: Register definition for MPC52xx

From: Grant Likely <hidden>
Date: 2005-07-17 07:06:05 

Here are additional register definitions for the MPC52xx.  CDM clock
enables and port config bit settings in mpc52xx.h.  Registers needed
to support non-UART PSC modes in mpc52xx_psc.h.  Drivers which use
these regs/bits are to follow once I'm happy with them, but I thought
that others may be interested in them now.

Cheers,
g.

These should be held off until the drivers are ready (and really only
what the drivers need).  Thanks!
