Message

Adding of dditional support to Cadence PCIe controller (i.e. pci-j721e.c)
for up to 4x lanes, and reworking of driver to define maximum lanes per
board configuration.

Changes from v1:
* Reworked 'PCI: j721e: Add PCIe 4x lane selection support' to not cause
  regressions on 1-2x lane platforms

Changes from v2:
* Correct dev_warn format string from %d to %u since lane count is a unsigned
  integer
* Update CC list

Matt Ranostay (3):
  PCI: j721e: Add PCIe 4x lane selection support
  PCI: j721e: Add per platform maximum lane settings
  PCI: j721e: Add warnings on num-lanes misconfiguration
