Hi Mani, thanks for the reminder.
Actually this patch set depends on my PERST# patch set [1], which adds
support for Root Port dts nodes and correctly adjusts the sequence of PERST#
assert/deassert and regulator/clock enable in pci-imx6 driver.
I will resend this series once the PERST# patch set been accepted.
