1 | * Texas Instruments SoC audio setups with TLV320AIC3X Codec |
| 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 | |
| ee2f615d HG |
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: | |

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. | |
