You mean SOC_DAPM_SINGLE_TLV() ? There is no _MUT_ variant AFAIK.
According to the datasheets of aic3106, aic3104:
0b0000 - 0b1000 is valid (0 - -12 dB)
0b1001 - 0b1110 is reserved, do not write these sequences to the register
0b1111 is disconnected.
And for fun the aic3007's reg20 for example:
0b0000 - 0dB
0b0001 - 0b0011 - reserved
0b0100 - -6dB
0b0101 - 0b0111 - reserved
0b1000 - -12dB
0b1001 - 0b1110 - reserved
0b1111 - disconnected
Note that the driver never had control for these gains and the aic3104 support
is following this behavior, but if we do it for aic3104 we should do it for
all other support codecs as well as a followup patch or series. IMHO.
