proposing P.R. from personal repo

[fabriceo]

Hi!

for some reason I wanted to run the standard sw_usb_audio for EVK_316 in CODEC_MASTER=1 instead of 0.
this requires a small change in the i2c init section that can be selected automatically by an #if/#else/#endif and also the BCLK_N (divider) register need to be modified when sample rate is changed.

I was about to raise a GitHub issue to log this request and realised I could propose a PR but not clue (officially) on how to proceed. can you tell us more on this ?

I d imagine:
fork the xmos repo
clone it locally
checkout a certain tag (latest release or develop branch ?)
create a feature branch as of this point
devlop, verify, test (no possibility to run the proposed python test)
update document files
propose PR
that's it ?

thanks
