From: Srinivas Kandagatla <srinivas.kandagatla@xxxxxxxxxx> On Lenovo ThinkPad T14s, the headset is connected via a HiFi Switch to support CTIA and OMTP headsets. This switch is used to minimise pop and click during headset type switching. This patchset adds required bindings and changes to codec and dts to tnable the regulator required to power this switch along with wiring up gpio that control the headset switching. Without this patchset, there will be lots of noise on headset and mic will not we functional. Changes since v1: - moved to using mux-controls. - fixed typo in regulator naming.
