[alsa-devel] [PATCH v3 1/2] ASoC: tlv320aic31xx: Add headphone/headset detection
by Andrew F. Davis 01 Apr '19

01 Apr '19

This device can detect the insertion/removal of headphones and headsets. Enable reporting this status by enabling this interrupt and forwarding this to upper-layers if a jack has been defined. This jack definition and the resulting operation from a jack detection event must currently be defined by sound card platform code until CODEC outputs to jack mappings can be defined generically.
