- Simplify __pci_find_next_cap_ttl() by replacing magic numbers with #defines, extracting fields with FIELD_GET(), etc (Hans Zhang) - Convert __pci_find_next_cap_ttl() to a PCI_FIND_NEXT_CAP() macro that takes a config space accessor function so we can also use it in cases where the usual config accessors aren't available (Hans Zhang) - Similarly convert pci_find_next_ext_capability() to a PCI_FIND_NEXT_EXT_CAP() macro (Hans Zhang) - Implement dwc, dwc endpoint, and cadence capability search interfaces on top of PCI_FIND_NEXT_CAP() and PCI_FIND_NEXT_EXT_CAP(), replacing the previous duplicated code (Hans Zhang) - Search for capabilities in the cadence core instead of hard-coding their offsets, which are subject to change (Hans Zhang) * pci/capability-search: PCI: cadence: Use cdns_pcie_find_*capability() to avoid hardcoding offsets PCI: cadence: Implement capability search using PCI core APIs PCI: dwc: ep: Implement capability search using PCI core APIs PCI: dwc: Implement capability search using PCI core APIs PCI: Refactor extended capability search into PCI_FIND_NEXT_EXT_CAP() PCI: Refactor capability search into PCI_FIND_NEXT_CAP() PCI: Clean up __pci_find_next_cap_ttl() readability
