[v13,0/5] PCI: add 4x lane support for pci-j721e controllers

Message

Siddharth Vadapalli Nov. 28, 2023, 5:43 a.m. UTC

Hello,

This series adds support to the pci-j721e PCIe controller for up to 4x Lane
configuration supported by TI's J784S4 SoC. Bindings are also added for
the num-lanes property which shall be used by the driver. The compatible
for J784S4 SoC is added.

This series is based on linux-next tagged next-20231128.

Regards,
Siddharth.

These patches have been floating around for a long time (v12 was almost
identical and was submitted back in April, without any review back then
already [1]), and it looks like reviewers are happy with it.

Could you merge them to get them in 6.8?

Thanks!
Maxime

Having a glance, it looks good to me, too.

Applied, so it should make it to 6.8.  Apologies for the delay.
