Subject: [PATCH v2 00/14] 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

v1 of the series can be found @ [1]

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.
