 Required properties:
  - compatible: should contain one of the following:

 Optional properties:
  - enable-gpios: gpio specifier used to enable chip
  - clocks: clock provided to the controller (SUSCLK_32KHZ)
+ - vddpa-supply: Bluetooth VDD PA regulator handle
+ - vddio-supply: Bluetooth VDD IO regulator handle
