Subject: [PATCH] ARM: 7235/1: irqdomain: export irq_domain_simple_ops for
!CONFIG_OF
irqdomain support is used in interrupt controller drivers that may not
have device tree support but only need the basic HW->Linux irq
translation. Rather than having each of these implement their own IRQ
domain, allow them to use the simple ops.
