Subject[PATCH 00/13] 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

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].
