"iis" is the i2s bus clock and i2s_opclk0, i2s_opclk1 are sources of the root
clk. i2s0 has internal mux to select the source of root clk and i2s1 and i2s2
doesn't have any such mux.
- #clock-cells: should be 1, this property must be present if the I2S device
is a clock provider in terms of the common clock bindings, described in
../clock/clock-bindings.txt.
- clock-output-names: from the common clock bindings, names of the CDCLK
I2S output clocks, suggested values are "i2s_cdclk0", "i2s_cdclk1",
"i2s_cdclk3" for the I2S0, I2S1, I2S2 devices recpectively.
There are following clocks available at the I2S device nodes:
CLK_I2S_CDCLK - the CDCLK (CODECLKO) gate clock,
CLK_I2S_RCLK_PSR - the RCLK prescaler divider clock (corresponding to the
IISPSR register),
CLK_I2S_RCLK_SRC - the RCLKSRC mux clock (corresponding to RCLKSRC bit in
IISMOD register).
Refer to the SoC datasheet for availability of the above clocks.
The CLK_I2S_RCLK_PSR and CLK_I2S_RCLK_SRC clocks are usually only available
in the IIS Multi Audio Interface (I2S0).
Note: Old DTs may not have the #clock-cells, clock-output-names properties
and then not use the I2S node as a clock supplier.

it can be specified via "clocks" if system has

If a clock is specified, it is

STA32X audio CODEC
The driver for this device only supports I2C.
Required properties:
- compatible: "st,sta32x"
- 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.
- Vdda-supply: regulator spec, providing 3.3V
- Vdd3-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.
This property has to be specified as '/bits/ 8' value.
- 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 chosen.
This properties have to be specified as '/bits/ 8' values.
- 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,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,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,invalid-input-detect-mute:
If present, automatic invalid input detect mute is enabled.
Example:
codec: sta32x@38 {
compatible = "st,sta32x";
reg = <0x1c>;
reset-gpios = <&gpio1 19 0>;
power-down-gpios = <&gpio1 16 0>;
st,output-conf = /bits/ 8 <0x3>; // set output to 2-channel
// (full-bridge) power,
// 2-channel data-out
st,ch1-output-mapping = /bits/ 8 <0>; // set channel 1 output ch 1
st,ch2-output-mapping = /bits/ 8 <0>; // set channel 2 output ch 1
st,ch3-output-mapping = /bits/ 8 <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.
