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.

arm: iop: specify PMUs are for XScale CPUs Now that we can specify which PMU variant we're likely to deal with, do so in the iop board code. This will allow us to split the ARMv6, ARMv7, and XScale PMU drivers.

ARM: pmu: remove arm_pmu_type enumeration The arm_pmu_type enumeration was initially introduced to identify different PMU types in the system, the usual one being that on the CPU (ARM_PMU_DEVICE_CPU). With the removal of the PMU reservation code and the introduction of devicetree bindings for the CPU PMU, the enumeration is no longer required. This patch removes the enumeration and updates the various CPU PMU platform devices so that they no longer pass an .id field referring to identify the PMU type.
