[POWERPC] mpc5200 device tree bindings refinement
Much needed refinement of mpc5200 device tree binding specifications. Short list: - drop mpc52xx designator; only two supported chips exist, 5200 and 5200b. It's premature to refer to them as '52xx'. - Specify optional 'model' and 'revision' properties in the soc5200 node - Specify reqiured 'cell-index' property to identify between multiple SOC devices of the same type. (Useful for arbitrating shared register access) - Specify optional 'port-number' property for adjusting the logical serial port assignments. - Specify optional 'has-wdt' property for gpt0 node. - Add system-frequency property to soc5200 node Signed-off-by: Grant Likely <grant.likely@secretlab.ca> Signed-off-by: Paul Mackerras <paulus@samba.org>
