The Apple PCIe controller requires some additional attention when
enabling an endpoint device, so that the RID gets correctly mapped to
a SID on its way to the IOMMU.
So far, we have need relying on a custom bus notifier to perform this
task, but Frank Li's series [1] is a better approach as it puts the
complexity in the core code instead of the host controller driver, and
this series builds on that:
- allow the new {en,dis}able_device() to be provided via pci_ecam_ops
- convert the Apple PCIe driver to that infrastructure
Patches on top of 6.13-rc1, plus Frank's v7 series.
