From 3d4641a42ccf1593b3f3a474ee7541727acbb8e0 Mon Sep 17 00:00:00 2001 From: Stephan Gerhold Date: Tue, 14 Dec 2021 15:20:46 +0100 Subject: ASoC: core: Add snd_soc_of_parse_pin_switches() from simple-card-utils The ASoC core already has several helpers to parse card properties from the device tree. Move the parsing code for "pin-switches" from simple-card-utils to a shared snd_soc_of_parse_pin_switches() function so other drivers can also use it to set up pin switches configured in the device tree.

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.
