Thanks. I have one change in my tree which I would like to get to the mainline
but it will need more interaction with others pl330 users.
It is about adding support for interrupt per channel feature.
For our case we have 8 channels and every channel has specific interrupt
+ we have one abort IRQ.

Based on the binding and Linux code two changes are necessary.
1. Extend AMBA_NR_IRQS because we have 9 IRQs
2. Driver change which is just register irqs when they are available.

Are these two changes OK for you?

Thanks,
Michal
