amlogic,axg-sound-card.txt (3138B)

      1Amlogic AXG sound card:
      2
      3Required properties:
      4
      5- compatible: "amlogic,axg-sound-card"
      6- model : User specified audio sound card name, one string
      7
      8Optional properties:
      9
     10- audio-aux-devs : List of phandles pointing to auxiliary devices
     11- audio-widgets : Please refer to widgets.txt.
     12- audio-routing : A list of the connections between audio components.
     13
     14Subnodes:
     15
     16- dai-link: Container for dai-link level properties and the CODEC
     17	    sub-nodes. There should be at least one (and probably more)
     18	    subnode of this type.
     19
     20Required dai-link properties:
     21
     22- sound-dai: phandle and port of the CPU DAI.
     23
     24Required TDM Backend dai-link properties:
     25- dai-format : CPU/CODEC common audio format
     26
     27Optional TDM Backend dai-link properties:
     28- dai-tdm-slot-rx-mask-{0,1,2,3}: Receive direction slot masks
     29- dai-tdm-slot-tx-mask-{0,1,2,3}: Transmit direction slot masks
     30				  When omitted, mask is assumed to have to no
     31				  slots. A valid must have at one slot, so at
     32				  least one these mask should be provided with
     33				  an enabled slot.
     34- dai-tdm-slot-num : Please refer to tdm-slot.txt.
     35		     If omitted, slot number is set to accommodate the largest
     36		     mask provided.
     37- dai-tdm-slot-width : Please refer to tdm-slot.txt. default to 32 if omitted.
     38- mclk-fs : Multiplication factor between stream rate and mclk
     39
     40Backend dai-link subnodes:
     41
     42- codec: dai-link representing backend links should have at least one subnode.
     43	 One subnode for each codec of the dai-link.
     44	 dai-link representing frontend links have no codec, therefore have no
     45	 subnodes
     46
     47Required codec subnodes properties:
     48
     49- sound-dai: phandle and port of the CODEC DAI.
     50
     51Optional codec subnodes properties:
     52
     53- dai-tdm-slot-tx-mask : Please refer to tdm-slot.txt.
     54- dai-tdm-slot-rx-mask : Please refer to tdm-slot.txt.
