Re: [PATCH V4 00/28] Enable Tegra PCIe root port features

[Manikanta Maddireddy <mmaddireddy@nvidia.com>]

Hi Lorenzo,

Thierry Ack'ed most of the patches, I am planning to address the review
comments for remaining two patches and publish V5. If you can review the
series, I will consolidate both the comments and address in V5.
