Inverting polarity for data i clock lines  for PCIe for IMX6

We are building one PCIe interface with Gigabit PCIe RGMII chip I210 where IMX6 is master.

I got that our data (Rx, TX) and also CLK comming from IMX6 are with inverted polarity in our PCB.

I know that generally PCIe standard should  allow inverting polarity for data but i am not sure for CLK.

Also I am not sure if it is valid for IMX6.

My question is:

 

Can I neglect data and clock polarity for both Data lines and CLK for IMX6 based PCIe system.

Thank in advance
