Subject: [PATCH v1 0/4] Add tfa9897 speaker/receiver modes switching

Two tfa9897 are used in tandem on some devices (eg. alcatel-idol347)
to drive two speakers, for both receiver (earpiece) and speaker modes.

This series:
1. adds a control to allow enabling only one tfa9897/speaker
   (for the typical phone-call usecase)
2. adds a control to switch between speaker and receiver modes
3. adds support for an optional gpio also used to switch modes

Stephan Gerhold (1):
  ASoC: codecs: tfa989x: Add switch to allow disabling amplifier

Vincent Knecht (3):
  ASoC: codecs: tfa989x: Add support for tfa9897 RCV bit
  ASoC: dt-bindings: nxp, tfa989x: Add rcv-gpios property for tfa9897
  ASoC: codecs: tfa989x: Add support for tfa9897 optional rcv-gpios
