Subject[RFC PATCH v12 0/5] PCI: rockchip: Move PCIe WAKE# handling into pci core
Date

Currently we are handling wake irq in mrvl wifi driver. Move it into
pci core.

Tested on my chromebook bob(with cros 4.4 kernel and mrvl wifi).


Changes in v12:
Enable the wake irq in noirq stage to avoid possible irq storm.

Changes in v11:
Only add irq definitions for PCI devices and rewrite the commit message.
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 (5):
dt-bindings: PCI: Add definition of PCIe WAKE# irq and PCI irq
of/irq: Adjust of_pci_irq parsing for multiple interrupts
mwifiex: Disable wakeup irq handling for pcie
PCI / PM: Add support for the PCIe WAKE# signal for OF
arm64: dts: rockchip: Move PCIe WAKE# irq to pcie port for Gru
