2015-03-24arm64: pmu: add support for interrupt-affinity propertyWill Deacon1-0/+1
Historically, the PMU devicetree bindings have expected SPIs to be listed in order of *logical* CPU number. This is problematic for bootloaders, especially when the boot CPU (logical ID 0) isn't listed first in the devicetree. This patch adds a new optional property, interrupt-affinity, to the PMU node which allows the interrupt affinity to be described using a list of phandled to CPU nodes, with each entry in the list corresponding to the SPI at the same index in the interrupts property.
