Timur Tabi 895d603f94 powerpc/fsl_msi: add support for the fsl, msi property in PCI nodes ... On Freescale parts with multiple MSI controllers, the controllers are combined into one "pool" of interrupts. Whenever a device requests an MSI interrupt, the next available interrupt from the pool is selected, regardless of which MSI controller the interrupt is from. This works because each PCI bus has an ATMU to all of CCSR, so any PCI device can access any MSI interrupt register. The fsl,msi property is used to specify that a given PCI bus should only use a specific MSI device. This is necessary, for example, with the Freescale hypervisor, because the MSI devices are assigned to specific partitions. Ideally, we'd like to be able to assign MSI devices to PCI busses within the MSI or PCI layers. However, there does not appear to be a mechanism to do that. Whenever the MSI layer wants to allocate an MSI interrupt to a PCI device, it just calls arch_setup_msi_irqs(). It would be nice if we could register an MSI device with a specific PCI bus. So instead we remember the phandles of each MSI device, and we use that to limit our search for an available interrupt. Whenever we are asked to allocate a new interrupt for a PCI device, we check the fsl,msi property of the PCI bus for that device. If it exists, then as we are looping over all MSI devices, we skip the ones that don't have a matching phandle.
