A client in the SOF (Sound Open Firmware) context is a device that needs to communicate with the DSP via IPC messages. The SOF core is responsible for serializing the IPC messages to the DSP from the different clients. One example of an SOF client would be an IPC test client that floods the DSP with test IPC messages to validate if the serialization works as expected. Multi-client support will also add the ability to split the existing audio cards into multiple ones, so as to e.g. to deal with HDMI with a dedicated client instead of adding HDMI to all cards.
This patch introduces descriptors for SOF client driver and SOF client device along with APIs for registering and unregistering a SOF client driver, sending IPCs from a client device and accessing the SOF core debugfs root entry.
Along with this, add a couple of new members to struct snd_sof_dev that will be used for maintaining the list of clients.

As you are creating new sysfs directories, you should have some documentation for them :(
Hi Greg,
We are not adding any sysfs entries in this series.
Thanks, Ranjani
