ALSA: Add new TLV types for dBwith min/max

2009-06-17T08:56:53+00:00

Add new types for TLV dB scale specified with min/max values instead
of min/step since the resolution can't match always with the one
a device provides.  For example, usb audio devices give 1/256 dB
resolution while ALSA TLV is based on 1/100 dB resolution.
The new min/max types have less problems because the possible
rounding error happens only at min/max.

This patch implements a TLV mechanism to transfer an additional information
like dB scale to the user space. The types might be extended in future.
