-Amlogic AXG sound card:
-
-Required properties:
-
-- compatible: "amlogic,axg-sound-card"
-- model : User specified audio sound card name, one string
-
-Optional properties:
-
-- audio-aux-devs : List of phandles pointing to auxiliary devices
-- audio-widgets : Please refer to widgets.txt.
-- audio-routing : A list of the connections between audio components.
-
-Subnodes:
-
-- dai-link: Container for dai-link level properties and the CODEC
- sub-nodes. There should be at least one (and probably more)
- subnode of this type.
-
-Required dai-link properties:
-
-- sound-dai: phandle and port of the CPU DAI.
-
-Required TDM Backend dai-link properties:
-- dai-format : CPU/CODEC common audio format
-
-Optional TDM Backend dai-link properties:
-- dai-tdm-slot-rx-mask-{0,1,2,3}: Receive direction slot masks
-- dai-tdm-slot-tx-mask-{0,1,2,3}: Transmit direction slot masks
- When omitted, mask is assumed to have to no
- slots. A valid must have at one slot, so at
- least one these mask should be provided with
- an enabled slot.
-- dai-tdm-slot-num : Please refer to tdm-slot.txt.
- If omitted, slot number is set to accommodate the largest
- mask provided.
-- dai-tdm-slot-width : Please refer to tdm-slot.txt. default to 32 if omitted.
-- mclk-fs : Multiplication factor between stream rate and mclk
-
-Backend dai-link subnodes:
-
-- codec: dai-link representing backend links should have at least one subnode.
- One subnode for each codec of the dai-link.
- dai-link representing frontend links have no codec, therefore have no
- subnodes
-
-Required codec subnodes properties:
-
-- sound-dai: phandle and port of the CODEC DAI.
-
-Optional codec subnodes properties:
-
-- dai-tdm-slot-tx-mask : Please refer to tdm-slot.txt.
