Is this firmware redistributable? I would assume not as like other Renesas IP
firmware. If so, you should add a documentation about how an user can get the
firmware, and package it. Like,
Documentation/PCI/controller/rcar-pcie-firmware.rst

I will do so in V2 .

The Gen4 firmware is now part of linux-firmware, so I updated that piece of documentation and sent a patch.

Since the runtime usage count is incremented and not dropped anywhere else, the
driver will never runtime suspend.

+}

I do not think we can actually runtime suspend the PHY itself, so this is expected.

The rest of the feedback is handled in V2, thank you !
