I'm waiting for the ack now, and will re-base them in a proper sequence later. This series patches add the i.MX8MP PCIe support and tested on i.MX8MM EVK and i.MX8MP EVk boards. The PCIe NVME works fine on both boards. - i.MX8MP PCIe PHY has two resets refer to the i.MX8MM PCIe PHY. Add one more PHY reset for i.MX8MP PCIe PHY accordingly. - Add the i.MX8MP PCIe PHY support in the i.MX8M PCIe PHY driver. And share as much as possible codes with i.MX8MM PCIe PHY. - Add the i.MX8MP PCIe support in binding document, DTS files, and PCIe driver. Main changes v1-->v2: - It's my fault forget including Vinod, re-send v2 after include Vinod and linux-phy@lists.infradead.org. - List the basements of this patch-set. The branch, codes changes and so on. - Clean up some useless register and bit definitions in #3 patch.
