This series of patches adds,
- Tegra root port features like Gen2, AER, etc
- Power and perf optimizations
- Fixes like "power up sequence", "dev_err prints", etc

This series of patches are tested on Tegra186 based Jetson-TX2, Tegra210
based Jetson-TX1, T124 based Jetson-TK1, Tegra20 and Tegra30 platforms.

Changes from V5 to V6:
  - Patch [V4, 20/27]: Replaced pcie_pme_disable_msi() with no_msi quirk

Changes from V4 to V5:
 - Patch [V4, 4/28]: Added blank line before block style comment
 - Patch [V4, 22/28]: "Access endpoint config only if PCIe link is up"
patch is dropped
 - Patch [V4, 27/28]:
* Updated reset gpio toggle logic to reflect active low usage
* Replaced kasprintf() with devm_kasprintf()
* Updated commit message with more information.

Changes from V3 to V4:
 - Patch [V3,27/29] is dropped
 - Patch [V3,28/29]: devm_gpiod_get_from_of_node() is directly used in
   pci-tegra driver instead of of_get_pci* wrapper function defined in
   Patch [V3,27/29].

Manikanta Maddireddy (27):
  soc/tegra: pmc: Export tegra_powergate_power_on()

Hi Lorenzo, Bjorn,

There's a build-time dependency from the PCI patches on patch 1 of this
series. I've already Acked that, so I think you should take it through
the PCI tree along with the rest of the series.

The only patch that I picked up is the DT change in patch 23, which is
decoupled from the others via DT, though the data that it adds to DT
will be used in patch 24.

Does that sound good to you?

Thierry

Yes, I will drop patch 20 too as requested. Is there a merge ordering
dependency between patch 23 and 24 ? If yes we should let Bjorn know
or you drop patch 23 and I will merge it via PCI, let us know.

Nope, I don't think there are any issues with ordering. Patch 23
basically just adds the DT content that will be used by patch 24 to
dynamically change the pinmux options. Without patch 24, the default
state will be applied, which is what the state will be on boot anyway.
Patch 24 without patch 23 would mean that the PCI driver will try to
select a pinctrl state which does not exist, but this is already handled
gracefully in pinctrl_pm_select_state().

Applied with exceptions discussed to pci/tegra for v5.3, please
have a thorough look and report back if I am missing something.
