Hi Vidya,

when you resend with review comments addressed, can you please reorder
the patches slightly? I think it's more natural to order them like this:

    dt-bindings: PCI: tegra: Add sideband pins configuration entries
    PCI: tegra: Add support to configure sideband pins
    dt-bindings: PCI: tegra: Add PCIe slot supplies regulator entries
    PCI: tegra: Add support to enable slot regulators
    arm64: tegra: Add configuration for PCIe C5 sideband signals
    arm64: tegra: Add PCIe slot supply information in p2972-0000 platform

Or perhaps even like this:

    dt-bindings: PCI: tegra: Add sideband pins configuration entries
    dt-bindings: PCI: tegra: Add PCIe slot supplies regulator entries
    PCI: tegra: Add support to configure sideband pins
    PCI: tegra: Add support to enable slot regulators
    arm64: tegra: Add configuration for PCIe C5 sideband signals
    arm64: tegra: Add PCIe slot supply information in p2972-0000 platform

That makes it more obvious that patches 1-2 need an Acked-by from Rob
and patches 1-4 need to go through Lorenzo's tree and that I'll pick up
patches 5-6.

Thierry
