Cirrus Logic Lochnagar Audio Development Board
Lochnagar is an evaluation and development board for Cirrus Logic
Smart CODEC and Amp devices. It allows the connection of most Cirrus
Logic devices on mini-cards, as well as allowing connection of
various application processor systems to provide a full evaluation
platform. Audio system topology, clocking and power can all be
controlled through the Lochnagar, allowing the device under test
to be used in a variety of possible use cases.
This binding document describes the binding for the audio portion
of the driver.
This binding must be part of the Lochnagar MFD binding:
[4] ../mfd/cirrus,lochnagar.txt
Required properties:
- compatible : One of the following strings:
"cirrus,lochnagar2-soundcard"
- #sound-dai-cells : Must be set to 1.
- clocks : Contains an entry for each entry in clock-names.
- clock-names : Must include the following clocks:
"mclk" Master clock source for the sound card, should normally
be set to LOCHNAGAR_SOUNDCARD_MCLK provided by the Lochnagar
clock driver.
Example:
lochnagar-sc {
compatible = "cirrus,lochnagar2-soundcard";
#sound-dai-cells = <1>;
clocks = <&lochnagar_clk LOCHNAGAR_SOUNDCARD_MCLK>;
clock-names = "mclk";

NXP Audio Mixer (AUDMIX).
The Audio Mixer is a on-chip functional module that allows mixing of two
audio streams into a single audio stream. Audio Mixer has two input serial
audio interfaces. These are driven by two Synchronous Audio interface
modules (SAI). Each input serial interface carries 8 audio channels in its
frame in TDM manner. Mixer mixes audio samples of corresponding channels
from two interfaces into a single sample. Before mixing, audio samples of
two inputs can be attenuated based on configuration. The output of the
Audio Mixer is also a serial audio interface. Like input interfaces it has
the same TDM frame format. This output is used to drive the serial DAC TDM
interface of audio codec and also sent to the external pins along with the
receive path of normal audio SAI module for readback by the CPU.
The output of Audio Mixer can be selected from any of the three streams
- serial audio input 1
- serial audio input 2
- mixed audio
Mixing operation is independent of audio sample rate but the two audio
input streams must have same audio sample rate with same number of channels
in TDM frame to be eligible for mixing.
Device driver required properties:
=================================
- compatible : Compatible list, contains "fsl,imx8qm-audmix"
- reg : Offset and length of the register set for the device.
- clocks : Must contain an entry for each entry in clock-names.
- clock-names : Must include the "ipg" for register access.
- power-domains : Must contain the phandle to AUDMIX power domain node
- dais : Must contain a list of phandles to AUDMIX connected
DAIs. The current implementation requires two phandles
to SAI interfaces to be provided, the first SAI in the
list being used to route the AUDMIX output.
Device driver configuration example:
======================================
audmix: audmix@59840000 {
compatible = "fsl,imx8qm-audmix";
reg = <0x0 0x59840000 0x0 0x10000>;
clocks = <&clk IMX8QXP_AUD_AUDMIX_IPG>;

* initial value 1 if updates done for the to driver would alter the operation
* of the microhone.
*
* Note: The microphone clock (pdmclk_min, pdmclk_max, duty_min, duty_max)
* parameters need to be set as defined in microphone data sheet. E.g. clock
* range 1.0 - 3.2 MHz is usually supported microphones. Some microphones are
* multi-mode capable and there may be denied mic clock frequencies between
* the modes. In such case set the clock range limits of the desired mode to
* avoid the driver to set clock to an illegal rate.
*
* The duty cycle could be set to 48-52% if not known. Generally these
* parameters can be altered within data sheet specified limits to match
* required audio application performance power.
*
* The microphone clock needs to be usually about 50-80 times the used audio
* sample rate. With highest sample rates above 48 kHz this can relaxed
* somewhat.
*
* The parameter wake_up_time describes how long time the microphone needs
* for the data line to produce valid output from mic clock start. The driver
* will mute the captured audio for the given time. The min_clock_on_time
