- plugged in and leave tip sense floating when not plugged in. Inverting jacks
- short tip sense when unplugged and float when plugged in.

- 0 = (Default) Non-inverted
- 1 = Inverted
+ 0 = (Default) Shorted to tip when unplugged, open when plugged.
+ This is "inverted tip sense (ITS)" in the datasheet.

+ 1 = Open when unplugged, shorted to tip when plugged.
+ This is "normal tip sense (TS)" in the datasheet.
- cirrus,ts-dbnc-rise : Debounce the rising edge of TIP_SENSE_PLUG. With no
debounce, the tip sense pin might be noisy on a plug event.
