Subject[PATCH v8 00/15] Add PCIe support to TI's J721E SoC
Date
TI's J721E SoC uses Cadence PCIe core to implement both RC mode
and EP mode.

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.
