The SOF (Sound Open Firmware) tree contains a lot of references in
topology files to 'codec_slave'/'codec_master' terms, which in turn
come from alsa-lib and ALSA/ASoC topology support at the kernel
level. These terms are no longer compatible with the guidelines
adopted by the kernel community [1] and need to change in
backwards-compatible ways.
The main/secondary terms typically suggested in guidelines don't mean
anything for clocks, this patchset suggests instead the use of
'provider' and 'follower' terms, with the 'codec' prefix kept to make
it clear that the codec is the reference. The CM/CF suffixes are also
replaced by CP/CF.
Only my 2 cents: It's just another word combo. See bellow for sources for others.
I would prefer probably provider/consumer . It sounds more technic.
Thanks Jaroslav for chiming in. I had a similar set of comments in
internal reviews, but we didn't really have any consensus and I have not
seen good guidance specifically for clocks.
Provider/consumer is typically used for discrete data exchange with some
sort of locking and buffer fullness metric, but for clocks we'd want
something that hints at one device following the timing defined by another.
"follow" or "track" seem clearer than 'consume' IMHO, but I will side
with the majority, this is an RFC which can be modified at will.
