The cs42l43 has both a SPI master and an I2S interface, in some
configurations 2 cs35l56 amplifiers are connected to these to provide
bass speakers whilst the cs42l43's internal speaker drivers are used for
the tweeters. Add UCM configuration for this type of system.

The logical/abstract names should not contains any chip or specific hardware
identification. Just use "Speaker Switch" and "Speaker Volume" to not confuse
users.
For my information - "AMPL/R Speaker Volume" is digital or analog volume control?
Thanks,
