[PATCH RESEND 0/3] alsa-lib/ASoC: use inclusive language for bclk/fsync/topology

[Pierre-Louis Bossart]

This patchset is just a rebase of the code suggested in September [1],
resent for convenience for comparison with kernel patches.

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 [2], standard organizations, 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 'consumer' terms, with the 'codec' prefix kept to make
it clear that the codec is the reference. The CM/CS suffixes are also
replaced by CP/CC.

It can be argued that the change of suffix is invasive, but finding a
replacement that keeps the M and S shortcuts has proven difficult in
quite a few contexts.

The previous definitions are kept for backwards-compatibility so this
change should not have any functional impact. It is suggested that new
contributions only use the new terms but there is no requirement to
transition immediately to the new definitions for existing code. Intel
will however update all its past contributions related to bit
clock/frame sync configurations immediately.

This patchset contains the alsa-lib changes only, the kernel changes
will be shared in a different patchset. The SOF firmware changes are
already applied, only topology-related changes will be modified after
alsa-lib changes.

Feedback welcome
