Hmm one more comment. This should containe the standard property:
reg = <0x02b0 0x4>;
And the parent SCM driver should claim the whole SCM GENERAL register
area as defined in "Table 13-68. GENERAL Register Summary" for omap3
for example. So that would be the following for the parent:
reg = <0x48002270 xxx>;
The size needs to be checked and it may need multiple regions or instances
defined. That way we can use the drivers/mfd/syscon.c SCM driver for all
the misc registers without having to redo the bindings.
Regards,
Tony
