[PATCH v2 2/4] [POWERPC] Update device tree binding for mpc5200 gpt

Marian Balakowicz m8 at semihalf.com
Fri Oct 19 04:44:24 EST 2007


Add 'fsl,' prefix to 'compatible' property for gpt nodes.
Add 'fsl,' prefix to empty, GPT0 specific 'has-wdt' property.

 5) General Purpose Timer nodes (child of soc5200 node)
 On the mpc5200 and 5200b, GPT0 has a watchdog timer function.  If the board
 design supports the internal wdt, then the device node for GPT0 should
-include the empty property 'has-wdt'.
+include the empty property 'fsl,has-wdt'.
 
 6) PSC nodes (child of soc5200 node)
 PSC nodes can define the optional 'port-number' property to force assignment
