Subject[PATCH v2 2/2] ASoC: simple-card: Read pin switches conf from devicetree
Date
When the routing path between a widget (e.g. "Speaker") and the codec
goes through an external amplifier, having a pin switch for this widget
allows the amplifier to be disabled when the widget is not to be used
(e.g. when using headphones).

Notes:
v2: - Rebase on top of for-next
- Rename to asoc_simple_parse_pin_switches()
