The high level features are: *) Supports Legacy, MSI and MSI-X interrupt *) Supports upto GEN4 speed mode *) Supports SR-IOV *) Supports multiple physical function *) Ability to route all transactions via SMMU This patch series *) Add support in Cadence PCIe core to be used for TI's J721E SoC *) Add a driver for J721E PCIe wrapper v1 of the series can be found @ [1] v2 of the series can be found @ [2] v3 of the series can be found @ [5] v4 of the series can be found @ [6] v5 of the series can be found @ [7] v6 of the series can be found @ [8] v7 of the series can be found @ [9] Changes from v7: 1) Replaced WARN with pr_warn 2) Included support for "dma-ranges" property patch in this series [10] Changes from v6: 1) Fixed bot found errors running 'make dt_binding_check' Changes from v5: 1) Added Reviewed-by: for PATCH #6 2) Protect writes to PCI_STATUS with spin_lock during raising interrupts in EP mode to reduce the time between read and write of RMW. Changes from v4: 1) Added Reviewed-by: & Acked-by: tags from RobH 2) Removed un-used accessors for pcie-cadence.h and removed having ops for read/write accessors 3) Updated cdns,cdns-pcie-host.yaml to remove "mem" from reg Changes from v3: 1) Changed the order of files in MAINTAINTERS file to fix Joe's comments 2) Fixed indentation and added Reviewed-by: Rob Herring <robh@kernel.org> 3) Cleaned up computing msix_tbl 4) Fixed RobH's comment on J721E driver Changes from v2: 1) Converting Cadence binding to YAML schema was done as a separate series [3] & [4]. [3] is merged and [4] is pending. 2) Included MSI-X support in this series 3) Added link down interrupt handling (only error message) 4) Rebased to latest 5.7-rc1 5) Adapted TI J721E binding to [3] & [4] Changes from v1: 1) Added DT schemas cdns-pcie-host.yaml, cdns-pcie-ep.yaml and cdns-pcie.yaml for Cadence PCIe core and included it in TI's PCIe DT schema. 2) Added cpu_addr_fixup() for Cadence Platform driver. 3) Fixed subject/description/renamed functions as commented by Andrew Murray.
