Add new compatible strings for the g12a devices. Audio wise, the g12a is fairly to close to the axg, yet some differences need to be handled. Signed-off-by: Jerome Brunet <jbrunet@baylibre.com> Signed-off-by: Mark Brown <broonie@kernel.org>

* Amlogic Audio PDM input
|
|
|
|
Required properties:
|
|
- compatible: 'amlogic,axg-pdm' or
|
|
'amlogic,g12a-pdm'
|
|
- reg: physical base address of the controller and length of memory
|
|
mapped region.
|
|
- clocks: list of clock phandle, one for each entry clock-names.
|
|
- clock-names: should contain the following:
|
|
* "pclk" : peripheral clock.
|
|
* "dclk" : pdm digital clock
|
|
* "sysclk" : dsp system clock
|
|
- #sound-dai-cells: must be 0.
|
|
|
|
Example of PDM on the A113 SoC:
|
|
|
|
pdm: audio-controller@ff632000 {
|
|
compatible = "amlogic,axg-pdm";
|
|
reg = <0x0 0xff632000 0x0 0x34>;
|
|
#sound-dai-cells = <0>;
|
|
clocks = <&clkc_audio AUD_CLKID_PDM>,
|
|
<&clkc_audio AUD_CLKID_PDM_DCLK>,
|
|
<&clkc_audio AUD_CLKID_PDM_SYSCLK>;
|
|
clock-names = "pclk", "dclk", "sysclk";
|
|
};
