[PATCH v2 0/2] Add TI K3 PCIe Endpoint Controller support for AM64X

[Hrushikesh Salunke]

Hello,

This series adds support for the Endpoint mode on Cadence PCIe controller 
on TI's K3 family of SoCs. The driver is an adaptation of the Linux 
driver (drivers/pci/controller/cadence/pci-j721e.c) and has been 
implemented specifically for Endpoint mode of operation on AM64X. A minor
set of changes will be sufficient to support other K3 SoCs as well.

This patch is tested on AM64X EVM. Following are the log corresponding
to this feature.
