ARM: 6048/1: ARM: iop3xx: register PMU IRQs during board initialisation
This patch adds an initcall for the iop3xx platforms so that they register their PMU IRQS with the PMU framework in the Kernel. Cc: Lennert Buytenhek <kernel@wantstofly.org> Signed-off-by: Will Deacon <will.deacon@arm.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
