Subject[PATCH V2 6/7] ARM: OMAP4+: Correct Wakeup-gen code to use physical irq number
Date
The wakeup gen mask/unmask callback uses the irq element of the
irq_data to setup. The irq is the linux virtual irq number and
is same as the hardware irq number only when the parent irqchip
is setup as a legacy domain. When it is used as a linear domain,
the virtual irqs are allocated dynamically and wakeup gen code
cannot rely on these numbers to access the irq registers. Instead
use the hwirq element of the irq_data which represent the physical
irq number.
