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
