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.
