There are two real examples for this in smartphones/tablets based on MSM8916: 1. Analog speaker amplifiers connected to headphone outputs. The MSM8916 analog codec does not have a separate "Line Out" port so some devices have an analog speaker amplifier connected to one of the headphone outputs. A pin switch is necessary to allow playback on headphones without also activating the speaker. 2. External speaker codec also used as earpiece. Some smartphones have two front-facing (stereo) speakers that can be also configured to act as an earpiece during voice calls. A pin switch is needed to allow disabling the second speaker during voice calls. There are existing bindings that allow setting up such pin switches in simple-card.yaml. Document the same for Qcom sound cards. One variant of example 1 above is added to the examples in the DT schema: There is an analog speaker amplifier connected to the HPH_R (right headphone channel) output. Adding a "Speaker" pin switch and widget allows turning off the speaker when audio should be only played via the connected headphones.

While they are usually used together for actual headphones output, some devices also have an analog speaker amplifier connected to one of the headphone channels. To allow modelling that properly (and to avoid powering on the unneeded output path), HPH_L and HPH_R should be represented by separate outputs rather than a shared HEADPHONE output that always activates both paths.
