From: Dharageswari R dharageswari.r@intel.com

A module is loaded when the path consisting the module is opened. The module binary(ies) is loaded from file system and cached in kernel memory for future use. This is downloaded to DSP using DMA and invoking Load module IPCs

This patch adds support for load/unload module IPCs, DMAing modules and manging the modules

A module can require extra memory for processing, like audio algorithms. The memory for these modules needs to be represented in base module configuration and passed to DSP on init, so add the memory pages as a field in widget data

For sending such payload we already support LARGE_CONFIG_SET IPCs and now to query such payload add LARGE_CONFIG_GET IPC

Some of the usecases can be marked as 'ignore_suspend' by machine. For these on suspend we should keep audio controller ON by saving the state and not suspending the device

For this we need to maintain a counter for these streams and be active on suspend when such a stream is opened.

From: Praveen Diwakar praveen.diwakar@intel.com

We should only add ignore suspend flag for some DAIs and not all. This patches removes it from the DAIs where we do not support this

It also marks the endpoints for which ignore_suspend should be enabled
