pcie-controller
Vendor: Generic or vendor-independent
Note
An implementation of a driver matching this compatible is available in drivers/pcie/host/pcie.c.
Description

Used to supply OSPM with the device’s PNP ID or ACPI ID. A node is consder as acpi based or not based on whether this property is present or not.
|
|
|
Provides OSPM with a logical device ID that does not change
across reboots. This object is optional, but is required when the device
has no other way to report a persistent unique device ID. The _UID must be
unique across all devices with either a common _HID or _CID.
|
|
|
Used to supply OSPM with a device’s Plug and Play-Compatible Device ID
|
Deprecated properties not inherited from the base binding file.
(None)
Properties inherited from the base binding file, which defines common properties that may be set on many nodes. Not all of these may apply to the “pcie-controller” compatible.

Do not initialize device automatically on boot. Device should be manually
initialized using device_init().
|
|
|
Property to identify that a device can be used as wake up source.
When this property is provided a specific flag is set into the
device that tells the system that the device is capable of
wake up the system.
Wake up capable devices are disabled (interruptions will not wake up
the system) by default but they can be enabled at runtime if necessary.
|
|
|
Automatically configure the device for runtime power management after the
init function runs.
