For driver debugfs, debugfs_remove_recursive() is called which is not
needed as it is already done in ASoC core debugfs. And a device managed
memory need not be freed explicitly as device core frees it up. So
remove unnecessary skl_debugfs_exit().

Commit bdd0384a5ada ("ASoC: Intel: Skylake: Add support to read firmware

missed adding sst-dsp.h as that leads to below compiler warning:

For debug, the kernel debugfs mechanism is available. We can add various

read etc.

DMA buffer size for gateway copier will be calculated based on:
For host DMA copier:
Input buffer size (ibs) for output direction (playback)
Output buffer size (obs) for input direction (capture)
For link DMA copier:
IBS for input direction (capture)
OBS for output direction (playback)
Update the driver to use the above.

With this patch, the dma buffer size is fetched from topology binary. This
buffer size is applicable for gateway copier modules.
Now that we can configure DSP dma buffer size, the device can support deep
buffer playback. DSP fetches large buffer and can result fewer wakes,
which helps in power reduction.

acpi_evaluate_dsm() and friends take a pointer to a raw buffer of 16
bytes. Instead we convert them to use guid_t type. At the same time we
convert current users.
acpi_str_to_uuid() becomes useless after the conversion and it's safe to
get rid of it.

In SKL+ platforms, all IPC commands are serialised, i.e. the driver sends
a new IPC to DSP, only after receiving a reply from the firmware for the
current IPC.
Hence it seems apparent that there is only a single modifier of the IPC RX
List. However, during an IPC timeout case in a multithreaded environment,
there is a possibility of the list element being deleted two times if not
properly protected.
So, use spin lock save/restore to prevent rx_list corruption.

The i915 component framework expects the caller to be invoking
snd_hdac_i915_init() from a thread context. Otherwise it results in
lockups on drm side.
So move the registering of component interface and probing of codecs on
this bus to a worker thread.
init_failed in skl structure is not used currently, so renamed to
init_done and used to track the initialization done in worker thread.

Module at the end of DSP pipeline that needs to be connected to a module
in another pipeline are represented as a PGA(leaf node) and in PGA event
handler these modules are bound/unbounded. Modules other than PGA leaf
can be connected directly or via switch to a module in another pipeline.
Example: reference path.
To support the deferred DSP module bind, following changes are done:
o When the path is enabled, the destination module that needs to be
bound may not be initialized. If the module is not initialized, add
these modules in a deferred bind list.
o When the destination module is initialized, check for these modules
in deferred bind list. If found, bind them.
o When the destination module is deleted, Unbind the modules.
o When the source module is deleted, remove the entry from the deferred
bind list.

As per hardware recommendation, for every capture stream completion
following operations need to be done in order to reflect the actual
data that is received in position buffer.
1. Wait for 20us before reading the DMA position in buffer once the
interrupt is generated for stream completion.
2. Read any of the register to flush the DMA position value. This is
dummy read operation.

When module size > DMA buffer size, driver copies first chunk and waits
for the BDL complete interrupt. BDL complete interrupt never occurs and
wait time expires as module load IPC is not send to start the DMA from
DSP.
To fix the above issue need to follow the below steps:
1. After copying the first chunk, send the module load IPC to start the
DMA.
2. Wait for the BDL interrupt. Once interrupt is received, copy the
next chunk.
3. Continue step 2 till all bytes are copied.
4. When all the bytes are copied (bytes_left = 0), wait for module load
IPC response
5. Handled module load IPC response messages, check the load module IPC
response and wake up the thread to complete module load.
