PCM512x audio CODECs These devices support both I2C and SPI (configured with pin strapping on the board). Required properties: - compatible : One of "ti,pcm5121", "ti,pcm5122", "ti,pcm5141" or "ti,pcm5142" - reg : the I2C address of the device for I2C, the chip select number for SPI. - AVDD-supply, DVDD-supply, and CPVDD-supply : power supplies for the device, as covered in bindings/regulator/regulator.txt Optional properties: - clocks : A clock specifier for the clock connected as SCLK. If this is absent the device will be configured to clock from BCLK. If pll-in and pll-out are specified in addition to a clock, the device is configured to accept clock input on a specified gpio pin. - pll-in, pll-out : gpio pins used to connect the pll using <1> through <6>. The device will be configured for clock input on the given pll-in pin and PLL output on the given pll-out pin. An external connection from the pll-out pin to the SCLK pin is assumed. Examples: pcm5122: pcm5122@4c { compatible = "ti,pcm5122"; reg = <0x4c>; AVDD-supply = <®_3v3_analog>; DVDD-supply = <®_1v8>; CPVDD-supply = <®_3v3>; }; pcm5142: pcm5142@4c { compatible = "ti,pcm5142"; reg = <0x4c>; AVDD-supply = <®_3v3_analog>; DVDD-supply = <®_1v8>; CPVDD-supply = <®_3v3>; clocks = <&sck>; pll-in = <3>; pll-out = <6>; };
