	Hi Thomas, Jason,

The renesas-intc-irqpin and renesas-irqc interrupt controllers are
cascaded to GICs. Hence when propagating wake-up settings to their parent
interrupt controllers, a lockdep warning is printed.

Avoid these false positive by using separate lockdep classes for IRQC
and INTC External IRQ Pin interrupts.

This depends on "[PATCH 0/2] irqchip: renesas: Propagate wake-up
settings to parent". Initially I didn't see the warnings on all
platforms due to another unrelated lockdep warning.

Thanks!
