Subject[PATCH v5 17/37] MIPS: JZ4740: define IRQ numbers based on number of intc IRQs
Date
For interrupts numbered after those of the interrupt controller, define
their numbers based upon the number of interrupts provided by the SoC
interrupt controller. This is in preparation for supporting newer
Ingenic SoCs which provide more interrupts.
