Subject: Re: [PATCH 2/4] PCI: dwc: dra7xx: Populate cpu_addr_fixup ops
Date: Mon, 20 Feb 2017 09:32:35 +0100	[thread overview]
Message-ID: <2636ef0f-78e1-b38a-5864-c53a645e7073@axis.com> (raw)

Hello Kishon!


It's nice to see that you are improving the dwc framework+drivers.

pcie-artpec6.c has the same quirk as dra7xx,
see define ARTPEC6_CPU_TO_BUS_ADDR.

I could create a patch, but I guess it would make more sense
if it's part of this series.

Keep up the good work!


Regards,
Niklas
