-Qualcomm Audio Front End (Q6AFE) binding
-
-AFE is one of the APR audio service on Q6DSP
-Please refer to qcom,apr.txt for details of the common apr service bindings
-used by all apr services. Must contain the following properties.
-
-- compatible:
- Usage: required
- Value type: <stringlist>
- Definition: must be "qcom,q6afe-v<MAJOR-NUMBER>.<MINOR-NUMBER>"
- Or "qcom,q6afe" where the version number can be queried
- from DSP.
- example "qcom,q6afe"
-
-= AFE DAIs (Digial Audio Interface)
-"dais" subnode of the AFE node. It represents afe dais, each afe dai is a
-subnode of "dais" representing board specific dai setup.
-"dais" node should have following properties followed by dai children.
-
-- compatible:
- Usage: required
- Value type: <stringlist>
- Definition: must be "qcom,q6afe-dais"

-
-== AFE DAI is subnode of "dais" and represent a dai, it includes board specific
-configuration of each dai. Must contain the following properties.
-
-- reg

-
-- qcom,sd-lines
- Usage: required for mi2s interface
- Value type: <prop-encoded-array>
- Definition: Must be list of serial data lines used by this dai.
- should be one or more of the 0-3 sd lines.
-
- - qcom,tdm-sync-mode:
- Usage: required for tdm interface
- Value type: <prop-encoded-array>
- Definition: Synchronization mode.
- 0 - Short sync bit mode
- 1 - Long sync mode

- Definition: Data out signal to drive with other masters.
- 0 - Disable
- 1 - Enable
-
- - qcom,tdm-invert-sync:
- Usage: required for tdm interface
- Value type: <prop-encoded-array>
- Definition: Invert the sync.
- 0 - Normal
- 1 - Invert
-
- - qcom,tdm-data-delay:
- Usage: required for tdm interface
- Value type: <prop-encoded-array>
- Definition: Number of bit clock to delay data
- with respect to sync edge.
- 0 - 0 bit clock cycle
- 1 - 1 bit clock cycle
- 2 - 2 bit clock cycle
-
- - qcom,tdm-data-align:
- Usage: required for tdm interface
- Value type: <prop-encoded-array>
- Definition: Indicate how data is packed
- within the slot. For example, 32 slot width in case of
- sample bit width is 24.
- 0 - MSB
- 1 - LSB
-
-= AFE CLOCKSS
-"clocks" subnode of the AFE node. It represents q6afe clocks
-"clocks" node should have following properties.
-- compatible:
- Usage: required
- Value type: <stringlist>
- Definition: must be "qcom,q6afe-clocks"
-
-- #clock-cells:
- Usage: required
- Value type: <u32>
- Definition: Must be 2. Clock Id followed by
- below valid clock coupling attributes.
- 1 - for no coupled clock
- 2 - for dividend of the coupled clock
- 3 - for divisor of the coupled clock
