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>;

    received mono data is in the left or right portion of the I2S frame

    according to the AD0 pin or directly via this configuration.

    0x0 (Default) = Selected by AD0 input (if AD0 = LOW, use left channel),

    0x2 = Left,

    0x1 = Selected by the inversion of the AD0 input (if AD0 = LOW, use right

  - VP-supply, VCP-supply, VD_FILT-supply, VL-supply, VA-supply :

  power supplies for the device, as covered in

  deasserted before communication to the codec starts.

  - interrupt-parent : Specifies the phandle of the interrupt controller to

  which the IRQs from CS42L42 are delivered to.

  (See Documentation/devicetree/bindings/interrupt-controller/interrupts.txt

  for further information relating to interrupt properties)

  - cirrus,ts-inv : Boolean property. For jacks that invert the tip sense

  polarity. Normal jacks will short tip sense pin to HS1 when headphones are

  plugged in and leave tip sense floating when not plugged in. Inverting jacks

  short tip sense when unplugged and float when plugged in.

  0 = (Default) Non-inverted

  1 = Inverted

  - cirrus,ts-dbnc-rise : Debounce the rising edge of TIP_SENSE_PLUG. With no

  debounce, the tip sense pin might be noisy on a plug event.

  0 - 0ms,

  1 - 125ms,

  2 - 250ms,

  3 - 500ms,

  4 - 750ms,

  5 - (Default) 1s,

  6 - 1.25s,

  7 - 1.5s,

  - cirrus,ts-dbnc-fall : Debounce the falling edge of TIP_SENSE_UNPLUG.

  With no debounce, the tip sense pin might be noisy on an unplug event.

  0 - 0ms,

  1 - 125ms,

  2 - 250ms,

  3 - 500ms,

  4 - 750ms,

  5 - (Default) 1s,

  6 - 1.25s,

  7 - 1.5s,

  - cirrus,btn-det-init-dbnce : This sets how long the driver sleeps after

  enabling button detection interrupts. After auto-detection and before

  servicing button interrupts, the HS bias needs time to settle. If you

  don't wait, there is possibility for erroneous button interrupt.

  0ms - 200ms,

  Default = 100ms

  - cirrus,btn-det-event-dbnce : This sets how long the driver delays after

  receiving a button press interrupt. With level detect interrupts, you want

  to wait a small amount of time to make sure the button press is making a

  clean connection with the bias resistors.

  0ms - 20ms,

  Default = 10ms

  - cirrus,bias-lvls : For a level-detect headset button scheme, each button

  will bias the mic pin to a certain voltage. To determine which button was

  pressed, the driver will compare this biased voltage to sequential,

  decreasing voltages and will stop when a comparator is tripped,

  indicating a comparator voltage < bias voltage. This value represents a

  percentage of the internally generated HS bias voltage. For different

  hardware setups, a designer might want to tweak this. This is an array of

  descending values for the comparator voltage.
