[PATCH v2 0/4] omap-abe-twl6040: Device tree support

[Peter Ujfalusi]

Hello,

Changes since v1:
- Binding docukentation updated with available pins and connectors
- dts section for abe-twl6040 sound configuration has been changed

Instead of dai link pairs only the nodes probed via DT have phandle:
ti,mcpdm; ti,dmic, ti,twl6040.
The driver in turn is responsible to handle the provided information.
To provide dai link pairs (cpu dai - codec) we would need Linux (ASoC) specific
nodes in DT for the dmic codec and twl6040 ASoC codec driver.

If the DT section have ti,dmic phandle the ASoC machine driver will register the
device to load the ASoC dmic-codec runtime.

Example dts section for audio support (SDP4430):
sound {
	compatible = "ti,abe-twl6040";
	ti,model = "SDP4430";

	ti,jack-detection = <1>;
	ti,mclk-freq = <38400000>;

	ti,mcpdm = <&mcpdm>;
	ti,dmic = <&dmic>;

	ti,twl6040 = <&twl6040>;

	/* Audio routing */
	ti,audio-routing =
		"Headset Stereophone", "HSOL",
		"Headset Stereophone", "HSOR",
		"Earphone Spk", "EP",
		"Ext Spk", "HFL",
		"Ext Spk", "HFR",
		"Line Out", "AUXL",
		"Line Out", "AUXR",
		"Vibrator", "VIBRAL",
		"Vibrator", "VIBRAR",
		"HSMIC", "Headset Mic",
		"Headset Mic", "Headset Mic Bias",
		"MAINMIC", "Main Handset Mic",
		"Main Handset Mic", "Main Mic Bias",
		"SUBMIC", "Sub Handset Mic",
		"Sub Handset Mic", "Main Mic Bias",
		"AFML", "Line In",
		"AFMR", "Line In",
		"DMic", "Digital Mic",
		"Digital Mic", "Digital Mic1 Bias";
};


Regards,
Peter
