c8eabf821c ASoC: Intel: Skylake: Fix a shift wrapping bug
"*val" is a u64.  It definitely looks like we intend to use the high 32
bits as well.

0730bd2e2a ASoC: Intel: Skylake: fix memory leak of module on error exit path
Currently there is a memory leak of module on a ENOMEM return path.
Fix this by kfree'ing module before returning.

55a92ea9cf ASoC: Intel: Skylake: Add table for module id for quick ref
Since modules ids are generated dynamically, we do not know the id
associate with modules in another pipelines. This limits our ability to
tell DSP about neighbouring modules.

So add a table for quick referencing of allocated module ids.

ef2a352cfb ASoC: Intel: Skylake: Use private instance id of modules in IPC
Use private id's of module instances that are generated during
init_module for the IPC messages to DSP. These id's are freed
up during delete pipeline.

700a9a63f9 ASoC: Intel: Skylake: Add module instance id generation APIs
Driver needs to send unique module instance id to firmware while
creating the module and uses this id to communicate with DSP for setting
parameters while audio use case is ongoing.

But, we have upper bound of instance ID. The current IDs are coming from
topology but it doesn't know the upper bound and can't assign unique
id's subject to upper bounds as we can create a big graph but not all
parts running at same time.

This patch adds a 128bit unique id management routines which are built
on top of ffz() for faster implementation. Unfortunately ffz() works on
32bits values, so additional code is added on top of ffz() to create a
128bit unique id.

33ece7f9c8 ASoC: Intel: Skylake: Remove dfw config and associated structures
The skl_dfw_config structure is no longer required as the module
config is populated by parsing and reading the token values.

So, remove the structure.

0556ba463b ASoC: Intel: Skylake: modify snd_skl_get_module_info args
snd_skl_get_module_info() takes skl_dfw_module as an argument. The users
then updates the topology data, so instead pass skl_module_cfg and let
snd_skl_get_module_info() fill that up.

a8e2c19efd ASoC: Intel: Skylake: add additional args to module parsing
For additional library parsing, we need to pass firmware to be
loaded and not use the pointer in context. Also, Library module
IDs are combination of library index and module ID in manifest.

So add the additional arguments of firmware and library offset to
snd_skl_parse_uuids().

ea6b3e9437 ASoC: Intel: Skylake: Add DSP firmware manifest parsing
Module params like module_id and loadable flag can be changed
in the DSP Firmware. These are kept in the firmware manifest
and driver should read these values from this manifest.

So, add support to parse the DSP firmware manifest and
read these module params.

6eee87261f ASoC: Intel: Skylake: Add strip extended manifest utility
Some upcoming platforms like broxton etc have extended manifest
in firmware binary. This is not required to be downloaded to DSP.
So driver needs to strip this before downloading.

Add a utility function to check if a header exists, and remove it
in that case
