If a specific platform has a need to modify parts of the bit allocation
but can reuse parts of the code, that's fine. The 'generic bandwidth
allocation' was meant to be a reference, not a one-size-fits-all solution.

We will use vkoul soundwire git repository as base and will post the
patch.

You might want to send this along with the actual user.

This is a dependent patch for our soundwire manager driver
patch series. Yesterday we have pushed this patch based on soundwire
git tree. If the patch is not picked, then we will resend this patch
as part of our patch series.
