The Designware core can be configured with up to four stereo channels. Each stereo channel is individually configured so, when the driver's hw_params call is made, each requested stereo channel has to be programmed.
This is quite unclear to someone who doesn't know the hardware, is this a bug fix or a new feature? It looks like it's a fix...
It is a fix. In the Designware core, each stereo channel is configured individually. So, when hw_params is called to configure N channels, N/2 stereo channels need to be configured in the core. The existing code doesn't do this and will only configure the highest numbered channel.
