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 Matt Ranostay (5): dt-bindings: PCI: ti,j721e-pci-*: add checks for num-lanes PCI: j721e: Add per platform maximum lane settings PCI: j721e: Add PCIe 4x lane selection support dt-bindings: PCI: ti,j721e-pci-*: add j784s4-pci-* compatible strings PCI: j721e: add j784s4 PCIe configuration .../bindings/pci/ti,j721e-pci-ep.yaml | 40 +++++++++++++++-- .../bindings/pci/ti,j721e-pci-host.yaml | 40 +++++++++++++++-- drivers/pci/controller/cadence/pci-j721e.c | 44 ++++++++++++++++--- 3 files changed, 113 insertions(+), 11 deletions(-) -- 2.38.GIT _______________________________________________ linux-arm-kernel mailing list linux-arm-kernel@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-arm-kernel
