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.

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";
