Subject: Merge branch 'pci/capability-search'
X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=fef353037982e3fd9aa38e2b8a7426768443777c;p=users%2Fhch%2Fmisc.git

Merge branch 'pci/capability-search'

- 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
