Add channel 1 and 2 input mixer registers and the related ALSA mixer controls for TAS5717/19 chips. The mixer control coefficients on the chip are linear in the range -3.99999 to +3.99999, encoded in 3.23 number format. In this patch the mixer controls are limited to 128 values from 0.0 to 1.0 in 1/64 steps. Signed-off-by: Petr Kulhavy <brain@jikos.cz> Signed-off-by: Mark Brown <broonie@kernel.org>
