Hi Krzystof:
Thanks for your review comments.
Sorry to reply late, since I'm taking the Spring Festival Vacation in the past days.
Got that. Would be changed later.

It's my fault that I'm trying to let fsl,imx6q-pcie.yaml to cover the binding
DT-schema for the Endpoint modes.

One standalone fsl,imx6q-pcie-ep.yaml should be created as DT-schema for i.MX
PCIe Endpoint modes.

I would summit next version a moment later. Please help to review them.
Thanks in advanced.
