    ASoC: Introduce SOC_SINGLE_S8_TLV() macro · dcc0799b
    Srinivas Kandagatla authored
    This patch introduces SOC_SINGLE_S8_TLV() macro for volume control
    on chips which supports both negative and positive gains with sign
    bit on a 8 bit register, Gain ranges from -128 to +127 with a
    predefined step size.
    Currently we only have support to DOUBLE_S8_TLV() which does not fit
    for cases where we just have separate gain control register for each
    channel.
    
    One of the Qualcomm SOC msm8916 has such gain control register whose gain
    range is from -38.4dB to +38.4dB with step size of 0.3dB.
