+Description: SoundWire Master-N DisCo properties.
+ These properties are defined by MIPI DisCo Specification
+ for SoundWire. They define various properties of the Master
+ and are used by the bus to configure the Master. clk_stop_modes
+ is a bitmask for simplifications and combines the
+ clock-stop-mode0 and clock-stop-mode1 properties.
