1PCM512x and TAS575x audio CODECs/amplifiers 2 3These devices support both I2C and SPI (configured with pin strapping 4on the board). The TAS575x devices only support I2C. 5 6Required properties: 7 8 - compatible : One of "ti,pcm5121", "ti,pcm5122", "ti,pcm5141", 9 "ti,pcm5142", "ti,tas5754" or "ti,tas5756" 10 11 - reg : the I2C address of the device for I2C, the chip select 12 number for SPI. 13 14 - AVDD-supply, DVDD-supply, and CPVDD-supply : power supplies for the 15 device, as covered in bindings/regulator/regulator.txt 16 17Optional properties: 18 19 - clocks : A clock specifier for the clock connected as SCLK. If this 20 is absent the device will be configured to clock from BCLK. If pll-in 21 and pll-out are specified in addition to a clock, the device is 22 configured to accept clock input on a specified gpio pin. 23 24 - pll-in, pll-out : gpio pins used to connect the pll using <1> 25 through <6>. The device will be configured for clock input on the 26 given pll-in pin and PLL output on the given pll-out pin. An 27 external connection from the pll-out pin to the SCLK pin is assumed. 28 Caution: the TAS-desvices only support gpios 1,2 and 3 29 30Examples: 31 32 pcm5122: pcm5122@4c { 33 compatible = "ti,pcm5122"; 34 reg = <0x4c>; 35 36 AVDD-supply = <®_3v3_analog>; 37 DVDD-supply = <®_1v8>; 38 CPVDD-supply = <®_3v3>; 39 }; 40 41 42 pcm5142: pcm5142@4c { 43 compatible = "ti,pcm5142"; 44 reg = <0x4c>; 45 46 AVDD-supply = <®_3v3_analog>; 47 DVDD-supply = <®_1v8>; 48 CPVDD-supply = <®_3v3>; 49 50 clocks = <&sck>; 51 pll-in = <3>; 52 pll-out = <6>; 53 }; 54
