intel,adsp-hda-host-out

Description

These nodes are “dma” bus nodes.

Intel ADSP HDA Host Out controller

Properties

Properties not inherited from the base binding file.

Name	Type	Details
`dma-channels`	`int`	Number of DMA channels supported by the controller This property is required.
`#dma-cells`	`int`	Number of items to expect in a DMA specifier This property is required. Constant value: `1`
`dma-buf-addr-alignment`	`int`	Memory address alignment requirement for DMA buffers used by the controller. This property is required.
`dma-buf-size-alignment`	`int`	Memory size alignment requirement for DMA buffers used by the controller. This property is required.
`dma-copy-alignment`	`int`	Minimal chunk of data possible to be copied by the controller. This property is required.
`dma-channel-mask`	`int`	Bitmask of available DMA channels in ascending order that are not reserved by firmware and are available to the kernel. i.e. first channel corresponds to LSB.
`dma-requests`	`int`	Number of DMA request signals supported by the controller.

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 “intel,adsp-hda-host-out” compatible.

Name	Type	Details
`reg`	`array`	register space This property is required. See Important properties for more information.
`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`	Human readable string describing the device (used as device_get_binding() argument) See Important properties for more information. This property is deprecated.
`clocks`	`phandle-array`	Clock gate information
`clock-names`	`string-array`	name of each clock
`#address-cells`	`int`	number of address cells in reg property
`#size-cells`	`int`	number of size cells in reg property
`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
`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.
`power-domain`	`phandle`	Power domain the device belongs to. The device will be notified when the power domain it belongs to is either suspended or resumed.
