@ -36,6 +36,10 @@ SAI subnodes required properties:
- pinctrl-names: should contain only value "default"
- pinctrl-0: see Documentation/devicetree/bindings/pinctrl/pinctrl-stm32.txt
The device node should contain one 'port' child node with one child 'endpoint'
node, according to the bindings defined in Documentation/devicetree/bindings/
graph.txt.
Example:
sound_card {
compatible = "audio-graph-card";
