FSL Driver load issues with OF

FSL Driver load issues with OF

[Benjamin Zores]

Hi there,

Since the progressive migration of some PPC drivers to use of_platform bus
(typically migrating OF parsing from fsl_soc.c to the device probe/init 
functions),
I'm experiencing driver load issues.

Actually, I'm not longer able to load of these drivers as the probe() 
function is never called.
Everything goes fine if I put code back to fsl_soc.c with the 
arch_initcall() command.

Example of drivers that do no longer load for me: gianfar, talitos ...
Is there something obvious that I've missed ?

Make sure your board is calling of_platform_bus_probe(), and that the
devices you're trying to probe are under buses described by the id list.

Thx for spotting this point.
When porting my custom board I indeed had a part of code that returned 
before of_platform_bus_probe()
can be called. Thx again, it now works fine.
