[alsa-devel] [PATCH 0/8] Enablement of BT I2S controller instance for AMD APUs

[Vijendar Mukunda]

This patch set updates Audio CoProcessor (ACP) audio drivers to enable
BT I2S controller instance. In Audio Coprocessor, There are three I2S
controllers can be configured/enabled.(I2S SP, I2S MICSP, BT I2S)
Default enabled I2S controller instance is I2S SP instance.
There is a requirement to enable BT I2S controller Instance along with
I2S SP controller instance. This patch set bring up functionality to render
& capture on BT I2S controller instance.

The current patch set also includes a new dependent patch.

The current code is based on asoc-next, but I'm happy to rebase on whatever
tree this ends up going through if there are any problems applying.
