Devicetree bindings for the Axentia TSE-850 audio complex



Required properties:

  - compatible: "axentia,tse850-pcm5142"

  - axentia,ssc-controller: The phandle of the atmel SSC controller used as

    cpu dai.

  - axentia,audio-codec: The phandle of the PCM5142 codec.

  - axentia,add-gpios: gpio specifier that controls the mixer.

  - axentia,loop1-gpios: gpio specifier that controls loop relays on channel 1.

  - axentia,loop2-gpios: gpio specifier that controls loop relays on channel 2.

  - axentia,ana-supply: Regulator that supplies the output amplifier. Must

    support voltages in the 2V - 20V range, in 1V steps.



The schematics explaining the gpios are as follows:



               loop1 relays

   IN1 +---o  +------------+  o---+ OUT1

            \                /

             +              +

             |   /          |

             +--o  +--.     |

             |  add   |     |

             |        V     |

             |      .---.   |

   DAC +----------->|Sum|---+

             |      '---'   |

             |              |

             +              +



   IN2 +---o--+------------+--o---+ OUT2

               loop2 relays



The 'loop1' gpio pin controlls two relays, which are either in loop position,

meaning that input and output are directly connected, or they are in mixer

position, meaning that the signal is passed through the 'Sum' mixer. Similarly

for 'loop2'.



In the above, the 'loop1' relays are inactive, thus feeding IN1 to the mixer

(if 'add' is active) and feeding the mixer output to OUT1. The 'loop2' relays

are active, short-cutting the TSE-850 from channel 2. IN1, IN2, OUT1 and OUT2

are TSE-850 connectors and DAC is the PCB name of the (filtered) output from

the PCM5142 codec.



Example:



	&i2c {

		codec: pcm5142@4c {

			compatible = "ti,pcm5142";



			reg = <0x4c>;



			AVDD-supply = <&reg_3v3>;

			DVDD-supply = <&reg_3v3>;

			CPVDD-supply = <&reg_3v3>;



			clocks = <&sck>;



			pll-in = <3>;

			pll-out = <6>;

		};

	};



	ana: ana-reg {

		compatible = "pwm-regulator";



		regulator-name = "ANA";



		pwms = <&pwm0 2 1000 PWM_POLARITY_INVERTED>;

		pwm-dutycycle-unit = <1000>;

		pwm-dutycycle-range = <100 1000>;



		regulator-min-microvolt = <2000000>;

		regulator-max-microvolt = <20000000>;

		regulator-ramp-delay = <1000>;

	};



	sound {

		compatible = "axentia,tse850-pcm5142";



		axentia,ssc-controller = <&ssc0>;

		axentia,audio-codec = <&codec>;



		axentia,add-gpios = <&pioA 8 GPIO_ACTIVE_LOW>;

		axentia,loop1-gpios = <&pioA 10 GPIO_ACTIVE_LOW>;

		axentia,loop2-gpios = <&pioA 11 GPIO_ACTIVE_LOW>;



		axentia,ana-supply = <&ana>;

	};
