This series add the i.MX PCIe EP mode support. And had been verified on i.MX8MQ, i.MX8MM EVK and i.MX8MP EVK boards. In the verification, one EVK board used as RC, the other one used as EP. Use the cross TX/RX differential cable connect the two PCIe ports of these two EVK boards. +-----------+ +------------+ | PCIe TX |<-------------->|PCIe RX | | | | | |EVK Board | |EVK Board | | | | | | PCIe RX |<-------------->|PCIe TX | +-----------+ +------------+ Main changes from v5 -> v6: - The v6 only contains the DTS changes, since PCIe part had been picked up. - Based on Shawn's for-next branch, and the following two patch-sets [1] and [2] issued by Marek, rebase the DTS changes.
