Based on the i.MX8MP GPC and blk-ctrl patch-set [1] issued by Lucas. This series patches add the i.MX8MP PCIe support. - 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. Tested on the i.MX8MM EVK and i.MX8MP EVK boards, PCIe works fine.
