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.
