[v1,0/3] ASoC: nau8822: add speaker Bridge Tied Output

From: Francesco Dolcini <francesco.dolcini@toradex.com>

Add support for BTL (Bridge Tied Load) configuration to NAU8822 audio codec,
since this requires adding a new property to the binding convert it from
txt to yaml first.

Emanuele Ghidoli (3):
  ASoC: dt-bindings: nau8822: convert to the dtschema
  ASoC: dt-bindings: nau8822: add nuvoton,spk-btl property to dtschema
  ASoC: nau8822: add speaker Bridge Tied Output configuration
