Documentation/devicetree/bindings/sound/tdm-slot.txt

+TDM slot:
+
+This specifies audio DAI's TDM slot.
+
+TDM slot properties:
+dai-tdm-slot-num : Number of slots in use.
+dai-tdm-slot-width :  Width in bits for each slot.
+
+For instance:
+	dai-tdm-slot-num = <2>;
+	dai-tdm-slot-width = <8>;
+
+And for each spcified driver, there could be one .of_xlate_tdm_slot_mask()
+to specify a explicit mapping of the channels and the slots. If it's absent
+the default snd_soc_of_xlate_tdm_slot_mask() will be used to generating the
+tx and rx masks.
+
+For snd_soc_of_xlate_tdm_slot_mask(), the tx and rx masks will use a 1 bit
+for an active slot as default, and the default active bits are at the LSB of
+the masks.

Documentation/devicetree/bindings/sound/widgets.txt

+Widgets:
+
+This mainly specifies audio off-codec DAPM widgets.
+
+Each entry is a pair of strings in DT:
+
+	"template-wname", "user-supplied-wname"
+
+The "template-wname" being the template widget name and currently includes:
+"Microphone", "Line", "Headphone" and "Speaker".
+
+The "user-supplied-wname" being the user specified widget name.
+
+For instance:
+	simple-audio-widgets =
+		"Microphone", "Microphone Jack",
+		"Line", "Line In Jack",
+		"Line", "Line Out Jack",
+		"Headphone", "Headphone Jack",
+		"Speaker", "Speaker External";
