Adding of additional 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
Changes from v3:
* Use the max_lanes setting per chip for the mask size required since
bootloader could have set num_lanes to a higher value that the
device tree which would leave in an undefined state
* Reorder patches do the previous change to not break bisect
* Remove line breaking for dev_warn to allow better grepping and since
no strict 80 columns anymore
Changes from v4:
* Correct invalid settings for j7200 PCIe RC + EP
* Add j784s4 configuration for selection of 4x lanes
Changes from v5:
* Dropped 'PCI: j721e: Add warnings on num-lanes misconfiguration' patch
from series
* Reworded 'PCI: j721e: Add per platform maximum lane settings' commit
message
* Added yaml documentation and schema checks for ti,j721e-pci-* lane
checking
Changes from v6:
* Fix wordwrapping in commit messages from ~65 columns to correct 75
columns
* Re-ran get_maintainers.pl to add missing maintainers in CC
Changes from v7:
* Addressed review comments in ti,j721e-pci-ep.yaml and
ti,j721e-pci-host.yaml from v6
* Added warn message if num-lanes property value is invalid.
* Addressed build issue reported in
https://lore.kernel.org/all/[email protected]/
Changes from v8:
* Use "const: 1" in ti,j721e-pci-ep.yaml and ti,j721e-pci-host.yaml
when num-lanes min and max values are equal.
Changes from v9:
* Rebase on next-20230315
Changes from v10:
* Rebase on next-20230317
Changes from v12:
* Rebase on next-20230331
