The MT6660 is a boosted BTL class-D amplifier with V/I sensing. A built-in DC-DC step-up converter is used to provide efficient power for class-D amplifier with multi-level class-G operation. The digital audio interface supports I2S, left-justified, right-justified, TDM and DSP A/B format for audio in with a data out used for chip information like voltage sense and current sense, which are able to be monitored via DATAO through proper Signed-off-by: Jeff Chang <jeff_chang@richtek.com> Link: https://lore.kernel.org/r/1579153597-23286-1-git-send-email-richtek.jeff.chang@gmail.com Signed-off-by: Mark Brown <broonie@kernel.org>
