Hi!

These patches are part of RFC series [1] ({43-46,48}/50),
these were dropped earlier as they weren't part of -rc release
at the time of posting now that patches have landed in v5.10-rc1
I am resending them with non-RFC tag.

[1] https://patchwork.kernel.org/project/cip-dev/
list/?series=363279&state=%2A&archive=both
Series looks good to me.

arch/arm64/boot/dts/renesas/r8a774a1.dtsi | 38 +++++++++++++++++++
arch/arm64/boot/dts/renesas/r8a774b1.dtsi | 38 +++++++++++++++++++

I see that the nodes are stil marked as "disabled"... I guess
devboards are not plugged into into PCIe hosts for the testing.
It's the same controller which works as a host and endpoint (PCIe EP). By default on the boards controller is enabled
as host and not EP as a result status is set to disabled. So during testing host is disabled and EP is enabled.
OK.


Anyway, it would be good to know if the merged -cip code was tested
and what was the result :-).
Attached are the results for G2M as PCIe host and G2N as PCIe EP tested on CIP kernel.

So on the host pcietest read/write/copy commands are tested (also lspci output)
Thank you for attaching the test results.
I will apply and push this series.


Cheers,
Prabhakar
Best regards,
Nobuhiro
