[RFC PATCH v11 0/5] PCI: rockchip: Move PCIe WAKE# handling into pci core

[Jeffy Chen]

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 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.
