'amlogic,axg-frddr'
- reg: physical base address of the controller and length of memory
mapped region.
- interrupts: interrupt specifier for the fifo.
- clocks: phandle to the fifo peripheral clock provided by the audio
clock controller.
- resets: phandle to memory ARB line provided by the arb reset controller.
- #sound-dai-cells: must be 0.
Example of FRDDR A on the A113 SoC:
frddr_a: audio-controller@1c0 {

Amlogic AXG sound card:
Required properties:
- compatible: "amlogic,axg-sound-card"
- model : User specified audio sound card name, one string
Optional properties:
- audio-aux-devs : List of phandles pointing to auxiliary devices
- audio-widgets : Please refer to widgets.txt.
- audio-routing : A list of the connections between audio components.
Subnodes:
- dai-link: Container for dai-link level properties and the CODEC
sub-nodes. There should be at least one (and probably more)
subnode of this type.
Required dai-link properties:
- sound-dai: phandle and port of the CPU DAI.
Required TDM Backend dai-link properties:
- dai-format : CPU/CODEC common audio format
Optional TDM Backend dai-link properties:
- dai-tdm-slot-rx-mask-{0,1,2,3}: Receive direction slot masks
- dai-tdm-slot-tx-mask-{0,1,2,3}: Transmit direction slot masks
When omitted, mask is assumed to have to no
slots. A valid must have at one slot, so at
least one these mask should be provided with
an enabled slot.
- dai-tdm-slot-num : Please refer to tdm-slot.txt.
If omitted, slot number is set to accommodate the largest
mask provided.
- dai-tdm-slot-width : Please refer to tdm-slot.txt. default to 32 if omitted.
- mclk-fs : Multiplication factor between stream rate and mclk
Backend dai-link subnodes:
- codec: dai-link representing backend links should have at least one subnode.
One subnode for each codec of the dai-link.
dai-link representing frontend links have no codec, therefore have no
subnodes
Required codec subnodes properties:
- sound-dai: phandle and port of the CODEC DAI.
Optional codec subnodes properties:
- dai-tdm-slot-tx-mask : Please refer to tdm-slot.txt.

RT5682 audio CODEC
This device supports I2C only.
Required properties:
- compatible : "realtek,rt5682" or "realtek,rt5682i"
- reg : The I2C address of the device.
Optional properties:
- interrupts : The CODEC's interrupt output.
- realtek,dmic1-data-pin
0: dmic1 is not used
1: using GPIO2 pin as dmic1 data pin
2: using GPIO5 pin as dmic1 data pin
- realtek,dmic1-clk-pin
0: using GPIO1 pin as dmic1 clock pin
1: using GPIO3 pin as dmic1 clock pin
- realtek,jd-src
0: No JD is used
1: using JD1 as JD source
- realtek,ldo1-en-gpios : The GPIO that controls the CODEC's LDO1_EN pin.
Pins on the device (for linking into audio routes) for RT5682:
* DMIC L1
* DMIC R1
* IN1P
* HPOL
* HPOR
Example:
rt5682 {
compatible = "realtek,rt5682i";
reg = <0x1a>;
interrupt-parent = <&gpio>;
interrupts = <TEGRA_GPIO(U, 6) GPIO_ACTIVE_HIGH>;
realtek,ldo1-en-gpios =
<&gpio TEGRA_GPIO(R, 2) GPIO_ACTIVE_HIGH>;
realtek,dmic1-data-pin = <1>;
realtek,dmic1-clk-pin = <1>;
realtek,jd-src = <1>;
