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/202211260346.4JvNnDdc-lkp@intel.com/
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.
