[PATCH v3 4/4] ARM: OMAP2+: board-generic: Use of_irq_init API

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Use the of_irq_init API introduced in 3.2 to handle
interrupt-controller with DT.
Update the irq_match table to map the proper XXX_of_init
functions for INTC and GIC drivers.
