* Amlogic Audio TDM formatters
Required properties:
- compatible: 'amlogic,axg-tdmin' or
'amlogic,axg-tdmout' or
'amlogic,g12a-tdmin' or
'amlogic,g12a-tdmout' or
'amlogic,sm1-tdmin' or
'amlogic,sm1-tdmout
- 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.
* "sclk" : bit clock.
* "sclk_sel" : bit clock input multiplexer.
* "lrclk" : sample clock
* "lrclk_sel": sample clock input multiplexer
Optional property:
- resets: phandle to the dedicated reset line of the tdm formatter.
Example of TDMOUT_A on the S905X2 SoC:
tdmout_a: audio-controller@500 {
compatible = "amlogic,axg-tdmout";
reg = <0x0 0x500 0x0 0x40>;
resets = <&clkc_audio AUD_RESET_TDMOUT_A>;
clocks = <&clkc_audio AUD_CLKID_TDMOUT_A>,
<&clkc_audio AUD_CLKID_TDMOUT_A_SCLK>,
<&clkc_audio AUD_CLKID_TDMOUT_A_SCLK_SEL>,
<&clkc_audio AUD_CLKID_TDMOUT_A_LRCLK>,
<&clkc_audio AUD_CLKID_TDMOUT_A_LRCLK>;
clock-names = "pclk", "sclk", "sclk_sel",
"lrclk", "lrclk_sel";
};
