Subject[PATCH 00/13] Add PCIe support to TI's J721E SoC
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

This is a trimmed down series of the initial RFC series [1].

Changes from RFC [1]:
*) Ability to route all transactions via SMMU is removed
*) SR-IOV support is removed
*) Miscellaneous improvement to endpoint core is removed

All these will be sent as smaller series.

I've also pushed the series along with device tree changes [2].

[1] ->
[2] -> j7_pci_v1

Kishon Vijay Abraham I (13):
PCI: cadence: Remove stray "pm_runtime_put_sync()" in error path
linux/kernel.h: Add PTR_ALIGN_DOWN macro
PCI: cadence: Add support to use custom read and write accessors
PCI: cadence: Add support to start link and verify link status
PCI: cadence: Add read and write accessors to perform only 32-bit
PCI: cadence: Allow pci_host_bridge to have custom pci_ops
PCI: cadence: Add new *ops* for CPU addr fixup
PCI: cadence: Use local management register to configure Vendor ID
dt-bindings: PCI: Add host mode dt-bindings for TI's J721E SoC
dt-bindings: PCI: Add EP mode dt-bindings for TI's J721E SoC
PCI: j721e: Add TI J721E PCIe driver
misc: pci_endpoint_test: Add J721E in pci_device_id table
MAINTAINERS: Add Kishon Vijay Abraham I for TI J721E SoC PCIe
