STA350 audio CODEC



The driver for this device only supports I2C.



Required properties:



  - compatible: "st,sta350"

  - reg: the I2C address of the device for I2C

  - reset-gpios: a GPIO spec for the reset pin. If specified, it will be

		 deasserted before communication to the codec starts.



  - power-down-gpios: a GPIO spec for the power down pin. If specified,

		      it will be deasserted before communication to the codec

		      starts.



  - vdd-dig-supply: regulator spec, providing 3.3V

  - vdd-pll-supply: regulator spec, providing 3.3V

  - vcc-supply: regulator spec, providing 5V - 26V



Optional properties:



  -  st,output-conf: number, Selects the output configuration:

	0: 2-channel (full-bridge) power, 2-channel data-out

	1: 2 (half-bridge). 1 (full-bridge) on-board power

	2: 2 Channel (Full-Bridge) Power, 1 Channel FFX

	3: 1 Channel Mono-Parallel

	If parameter is missing, mode 0 will be enabled.



  -  st,ch1-output-mapping: Channel 1 output mapping

  -  st,ch2-output-mapping: Channel 2 output mapping

  -  st,ch3-output-mapping: Channel 3 output mapping

	0: Channel 1

	1: Channel 2

	2: Channel 3

	If parameter is missing, channel 1 is choosen.



  -  st,thermal-warning-recover:

	If present, thermal warning recovery is enabled.



  -  st,thermal-warning-adjustment:

	If present, thermal warning adjustment is enabled.



  -  st,fault-detect-recovery:

	If present, then fault recovery will be enabled.



  -  st,ffx-power-output-mode: string

	The FFX power output mode selects how the FFX output timing is

	configured. Must be one of these values:

	  -  "drop-compensation"

	  -  "tapered-compensation"

	  -  "full-power-mode"

	  -  "variable-drop-compensation" (default)



  -  st,drop-compensation-ns: number

	Only required for "st,ffx-power-output-mode" ==

	"variable-drop-compensation".

	Specifies the drop compensation in nanoseconds.

	The value must be in the range of 0..300, and only

	multiples of 20 are allowed. Default is 140ns.



  -  st,overcurrent-warning-adjustment:

	If present, overcurrent warning adjustment is enabled.



  -  st,max-power-use-mpcc:

	If present, then MPCC bits are used for MPC coefficients,

	otherwise standard MPC coefficients are used.



  -  st,max-power-corr:

	If present, power bridge correction for THD reduction near maximum

	power output is enabled.



  -  st,am-reduction-mode:

	If present, FFX mode runs in AM reduction mode, otherwise normal

	FFX mode is used.



  -  st,odd-pwm-speed-mode:

	If present, PWM speed mode run on odd speed mode (341.3 kHz) on all

	channels. If not present, normal PWM spped mode (384 kHz) will be used.



  -  st,distortion-compensation:

	If present, distortion compensation variable uses DCC coefficient.

	If not present, preset DC coefficient is used.



  -  st,invalid-input-detect-mute:

	If not present, automatic invalid input detect mute is enabled.







Example:



codec: sta350@38 {

	compatible = "st,sta350";

	reg = <0x1c>;

	reset-gpios = <&gpio1 19 0>;

	power-down-gpios = <&gpio1 16 0>;

	st,output-conf = <0x3>;			// set output to 2-channel

						// (full-bridge) power,

						// 2-channel data-out

	st,ch1-output-mapping = <0>;		// set channel 1 output ch 1

	st,ch2-output-mapping = <0>;		// set channel 2 output ch 1

	st,ch3-output-mapping = <0>;		// set channel 3 output ch 1

	st,max-power-correction;		// enables power bridge

						// correction for THD reduction

						// near maximum power output

	st,invalid-input-detect-mute;		// mute if no valid digital

						// audio signal is provided.
