Can we configure/change this field in platform specific .dts file?
OR
Is there condition based configuration possible in DT?
To be specific,
I am adding support for AM335x EVM (using all your DT support patches),
The device is considered as OMAP3 variant and when it comes to INTC support,
I need to configure it to value "128", rest everything is same
(including base add).
Can I do something like
File - am335x-evm.dts
/include/ "omap3.dtsi"
....
Again change the specific fields of " intc: interrupt-controller"?
....
How can this be handled?
Thanks,
