[PATCH v2 2/2] PCI: imx6: Align EP link start behavior with documentation
Posted by Richard Zhu 4 months ago
According to PCI/endpoint/pci-endpoint-cfs.rst, the endpoint (EP) should
only link up after `echo 1 > start` is executed.

To match the documented behavior, do not start the link automatically
when adding the EP controller.
