[PATCH] soundwire: Add generic bandwidth allocation algorithm

[Jaroslav Kysela]

Dne 08. 09. 20 v 15:15 Bard Liao napsal(a):
> This algorithm computes bus parameters like clock frequency, frame
> shape and port transport parameters based on active stream(s) running
> on the bus.
> 
> Developers can also implement their own .compute_params() callback for
> specific resource management algorithm, and set if before calling
> sdw_add_bus_master()
> 
> Credits: this patch is based on an earlier internal contribution by
> Vinod Koul, Sanyog Kale, Shreyas Nc and Hardik Shah. All hard-coded
> values were removed from the initial contribution to use BIOS
> information instead.

I did testing and I've not found any issues. The abstraction looks good.
