pci-host-ecam-generic

Note

An implementation of a driver matching this compatible is available in drivers/pcie/host/pcie_ecam.c.

Description

These nodes are “pcie” bus nodes.

PCIe Controller in ECAM mode

Properties

Properties not inherited from the base binding file.

Name	Type	Details
`msi-parent`	`phandle`
`ranges`	`array`	As described in IEEE Std 1275-1994, but must provide at least a definition of non-prefetchable memory. One or both of prefetchable Memory and IO Space may also be provided. This property is required.
`interrupt-map-mask`	`array`
`interrupt-map`	`compound`
`bus-range`	`array`
`acpi-hid`	`string`	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.
`acpi-uid`	`string`	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.
`acpi-comp-id`	`string-array`	Used to supply OSPM with a device’s Plug and Play-Compatible Device ID

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 “pci-host-ecam-generic” compatible.

Name	Type	Details
`reg`	`array`	register space This property is required. See Important properties for more information.
`#address-cells`	`int`	number of address cells in reg property This property is required.
`#size-cells`	`int`	number of size cells in reg property This property is required.
`status`	`string`	indicates the operational status of a device Legal values: `'ok'`, `'okay'`, `'disabled'`, `'reserved'`, `'fail'`, `'fail-sss'` See Important properties for more information.
`compatible`	`string-array`	compatible strings This property is required. See Important properties for more information.
`reg-names`	`string-array`	name of each register space
`interrupts`	`array`	interrupts for device See Important properties for more information.
`interrupts-extended`	`compound`	extended interrupt specifier for device
`interrupt-names`	`string-array`	name of each interrupt
`interrupt-parent`	`phandle`	phandle to interrupt controller node
`label`	`string`	No description provided for this label See Important properties for more information.
`clocks`	`phandle-array`	Clock gate information
`clock-names`	`string-array`	name of each clock
`dmas`	`phandle-array`	DMA channels specifiers
`dma-names`	`string-array`	Provided names of DMA channel specifiers
`io-channels`	`phandle-array`	IO channels specifiers
`io-channel-names`	`string-array`	Provided names of IO channel specifiers
`mboxes`	`phandle-array`	mailbox / IPM channels specifiers
`mbox-names`	`string-array`	Provided names of mailbox / IPM channel specifiers
`power-domains`	`phandle-array`	Power domain specifiers
`power-domain-names`	`string-array`	Provided names of power domain specifiers
`#power-domain-cells`	`int`	Number of cells in power-domains property
`zephyr,deferred-init`	`boolean`	Do not initialize device automatically on boot. Device should be manually initialized using device_init().
`wakeup-source`	`boolean`	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.
`zephyr,pm-device-runtime-auto`	`boolean`	Automatically configure the device for runtime power management after the init function runs.
`zephyr,disabling-power-states`	`phandles`	List of power states that will disable this device power.
