1Marvell PXA SSP CPU DAI bindings 2 3Required properties: 4 5 compatible Must be "mrvl,pxa-ssp-dai" 6 port A phandle reference to a PXA ssp upstream device 7 8Optional properties: 9 10 clock-names 11 clocks Through "clock-names" and "clocks", external clocks 12 can be configured. If a clock names "extclk" exists, 13 it will be set to the mclk rate of the audio stream 14 and be used as clock provider of the DAI. 15 16Example: 17 18 /* upstream device */ 19 20 ssp1: ssp@41000000 { 21 compatible = "mrvl,pxa3xx-ssp"; 22 reg = <0x41000000 0x40>; 23 interrupts = <24>; 24 clock-names = "pxa27x-ssp.0"; 25 }; 26 27 /* DAI as user */ 28 29 ssp_dai0: ssp_dai@0 { 30 compatible = "mrvl,pxa-ssp-dai"; 31 port = <&ssp1>; 32 #sound-dai-cells = <0>; 33 }; 34 35
