Hi Manikanta,

I don't see any update on this series after comments.

Is there  any plans to take up this series.

Thanks & Regards,

Krishna Chaitanya.

Below series [1] attempted to support DT based PCIe wake feature in generic
PCI core driver. This series was left at v13 and final comments are not
addressed. I am continuing this series from v14 by addressing all comments
in v13. I dropped rockchip device tree patch because I don't have hardware
to verify it. Instead, I verified these patches on NVIDIA Jetson AGX Orin
Developer Kit and included its device tree changes in this series.

[1] https://lore.kernel.org/all/20171226023646.17722-1-jeffy.chen@xxxxxxxxxxxxxx/

Changes in v14:
Updated commit message for DT bindings patch to reflect that DT properties
are tied to PCI-PCI Bridge.
Addressed review comments on PCI interrupt parsing patch.
Dropped rockchip device tree patch.
Added Jetson AGX OrinDeveloper Kit device tree and Tegra PMC patches.

Changes in v13:
Fix compiler error reported by kbuild test robot <fengguang.wu@xxxxxxxxx>

Changes in v12:
Only add irq definitions for PCI devices and rewrite the commit message.
Enable the wake irq in noirq stage to avoid possible irq storm.

Changes in v11:
Address Brian's comments.
Only support 1-per-device PCIe WAKE# pin as suggested.
Move to pcie port as Brian suggested.

Changes in v10:
Use device_set_wakeup_capable() instead of device_set_wakeup_enable(),
since dedicated wakeirq will be lost in device_set_wakeup_enable(false).

Changes in v9:
Add section for PCI devices and rewrite the commit message.
Fix check error in .cleanup().
Move dedicated wakeirq setup to setup() callback and use
device_set_wakeup_enable() to enable/disable.
Rewrite the commit message.

Changes in v8:
Add optional "pci", and rewrite commit message.
Add pci-of.c and use platform_pm_ops to handle the PCIe WAKE# signal.
Rewrite the commit message.

Changes in v7:
Move PCIE_WAKE handling into pci core.

Changes in v6:
Fix device_init_wake error handling, and add some comments.

Changes in v5:
Move to pci.txt
Rebase.
Use "wakeup" instead of "wake"

Changes in v3:
Fix error handling.

Changes in v2:
Use dev_pm_set_dedicated_wake_irq.

Jeffy Chen (3):
   dt-bindings: PCI: Add definition of PCIe WAKE# irq and PCI irq
   of/irq: Adjust of_pci_irq parsing for multiple interrupts
   PCI / PM: Add support for the PCIe WAKE# signal for OF

Manikanta Maddireddy (2):
   arm64: tegra: Add PCIe port node with PCIe WAKE# for C1 controller
   soc/tegra: pmc: Add Tegra234 PCIe wake event
