It is used for headphones on some devices, eg. alcatel-idol347.

Can you please add suffix to these defines something like:
#define SPKR_CTL_TLMM_WS_EN_SEL_SECONDARY BIT(18)
so it becomes more obvious, As we have 4 possible values for this field
[18:19]
same for WS_OUT_SEL.
Also you should make sure that other bits in this fields are cleared
before writing.
