Merge branch 'pci/controller/cadence'
- Add j721e DT and driver support for 'num-lanes' for devices that support
x1, x2, or x4 Links (Matt Ranostay)
- Add j721e DT compatible strings and driver support for j784s4 (Matt Ranostay)
- Make TI J721E Kconfig depend on ARCH_K3 since the hardware is specific to
those TI SoC parts (Peter Robinson)
* pci/controller/cadence:
PCI: j721e: Make TI J721E depend on ARCH_K3
PCI: j721e: Add TI J784S4 PCIe configuration
PCI: j721e: Add PCIe 4x lane selection support
PCI: j721e: Add per platform maximum lane settings
dt-bindings: PCI: ti,j721e-pci-*: Add j784s4-pci-* compatible strings
dt-bindings: PCI: ti,j721e-pci-*: Add checks for num-lanes
