I've pasted below the topology data for the broadwell firmware using the text file format being used by UCM. Using the UCM format allows to to share parser code and allows us to also have UCM define topology data.
I've not yet completed the byte or enum controls but the rest of the data is there for comments. I've also included the recent channel changes suggested in the UAPI header comments.
# Firmware Topology Configuration for Broadwell
# TLV scale used by both global and stream volumes SectionTLV."hsw_vol_tlv" {
DBScale [ min "-9000" step "300" mute "1" ] }
So for our DSP we need to pass some private data, how do we go about describing it for this and other controls?
# Controls from default pipeline SectionControl."Default Pipeline" {
Index "1"
# Master DSP volume Mixer [ name "Master Playback Volume" Channel.0 [ map "Left" reg "0" shift "0" ] Channel.1 [ map "Right" reg "0" shift "8" ] max "31" invert "false" get "0" put "0"
what do these two mean?
tlv_array "hsw_vol_tlv"]

Is this a FE or a BE? How about Dailinks?
