| 2 | |
| 3 | Required properties: |
| 4 | - compatible : "ti,da830-evm-audio" : forDM365/DA8xx/OMAPL1x/AM33xx |
| 5 | - ti,model : The user-visible name of this sound complex. |
| 6 | - ti,audio-codec : The phandle of the TLV320AIC3x audio codec |
| 7 | - ti,mcasp-controller : The phandle of the McASP controller |
| 8 | - ti,audio-routing : A list of the connections between audio components. |
| 9 | Each entry is a pair of strings, the first being the connection's sink, |
| 10 | the second being the connection's source. Valid names for sources and |
| 11 | sinks are the codec's pins, and the jacks on the board: |
| 12 | |
| 13 | Optional properties: |
| 14 | - ti,codec-clock-rate : The Codec Clock rate (in Hz) applied to the Codec. |
| 15 | - clocks : Reference to the master clock |
| 16 | - clock-names : The clock should be named "mclk" |
| 17 | - Either codec-clock-rate or the codec-clock reference has to be defined. If |
| 18 | the both are defined the driver attempts to set referenced clock to the |
| 19 | defined rate and takes the rate from the clock reference. |
| 20 | |
| 21 | Board connectors: |
| 22 | |
| 23 | * Headphone Jack |
| 24 | * Line Out |
| 25 | * Mic Jack |
| 26 | * Line In |
