This patch adds controllers for digital volume of PCM output. Volume effects simply linear, not dB scale as follows: Gained PCM = Original * 0x4000 / Volume The value range of volume is from 0x0001 to 0xffff. 0x0000 works as mute. Initial value is 0x4000 (+0dB). Signed-off-by: Katsuhiro Suzuki <suzuki.katsuhiro@socionext.com> Signed-off-by: Mark Brown <broonie@kernel.org> |
