Hi Lucas: Can you help to take a look at this v4 series, and give your ack for other 4 patches of this patch-set if you're fine with them? Thus, I can ping Lorenzo to help merge the v4 set firstly before the merger of the i.MX8MM PCIe support patches. Thanks in advanced.

Just move the imx6_pcie_clk_disable() to an earlier place without function changes, since it wouldn't be only used in imx6_pcie_suspend_noirq() later.
