Subject: ASoC: intel: make function stub static

This function stub should have been 'static' in the original patch
so that multiple uses of the header file (in different drivers)
will not cause multiple function definitions.

sound/soc/intel/boards/built-in.o: In function `sst_acpi_find_name_from_hid':
(.text+0x560): multiple definition of `sst_acpi_find_name_from_hid'
sound/soc/intel/atom/built-in.o:(.text+0x10610): first defined here
../scripts/Makefile.build:369: recipe for target 'sound/soc/intel/built-in.o' failed

Fixes: f17131a93f43: add function stub when ACPI is not enabled

Subject: 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

From ea6b3e943787b996487605f853295397c52e51fd Mon Sep 17 00:00:00 2001
From: Shreyas NC <shreyas.nc@intel.com>
Date: Mon, 30 May 2016 17:42:59 +0530
Subject: 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.

Subject: ASoC: Intel: Skylake: Reset DSP pipe when host/link DMA is reset

In case of XRUN recovery PCM prepare will be called. In this case
Host/Link DMAs are reset and reconfigured, hence the corresponding
FE/BE pipe needs to be reset in order to get to a clean state.

Subject: ASoC: Intel: Skylake: Create Pipe to widget list in soc probe

We need to Identify the DSP pipe type and based on it being a pass
thru pipeline or not, we need to copy the pipeline params.

Pipe to widget mapping was earlier done in pre PMD widget handler,
but since the pipe type would now be required in hw_params for
bypass pipelines we need to move this to be done during the ASoC
probe of the platform component.

Subject: ASoC: Intel: Skylake: Set the DSP pipe type

DSP pipe type can be a pass through or it can be processing pipe.
In case of pass through pipe, it is a single pipeline with both
host and link copier in the same pipeline.

Identify the DSP pipe type if it pass through or not. Pass through
pipe is identified by checking if it has both host and link copier
in the same pipeline.

Subject: ASoC: Intel: Skylake: Enable firmware reload in suspend

Broxton DSP needs retains code loaded during runtime_pm cycles.
But it looses that on suspend cycle, so on resume we need to
download the firmware again.

This is done by adding a new flag and based on flag status, we
download the firmware.

Subject: ASoC: Intel: Skylake: Update FW purge for Broxton

Broxton needs to send Purge firmware IPC to DSP before downloading the
firmware. The DMA id needs to be updated for that.

While at it also update Broxton boot sequence to send purge request after
power up and before yanking off reset.

Subject: ASoC: Intel: Skylake: Check for module list being NULL

While clearing loaded module count, we should check first to see
if module list is NULL or not. Some distributions can ship with
no modules and thus list can be empty.

Randy reported following error when ACPI is not enabled:

warning: (SND_SOC_INTEL_BYTCR_RT5640_MACH && SND_SOC_INTEL_BYTCR_RT5651_MACH

SND_SOC_INTEL_CHT_BSW_MAX98090_TI_MACH) selects SND_SST_IPC_ACPI
+which has unmet direct dependencies (SOUND && !M68K && !UML && SND &&
SND_SOC && ACPI)

causing these build errors:

CONFIG_SND_SST_IPC_ACPI was already dependent upon ACPI, but that was not
solving it. So move the depends up to machine drivers and remove from
CONFIG_SND_SST_IPC_ACPI.

Subject: ASoC: Intel: Skylake: Add DSP muti-core infrastructure

The DSP can have more than one cores. In that case the secondary
core has to be managed by the driver. This patch adds the changes
to driver infrastructure to support multiple core.

A new object skl_dsp_cores is introduced to support multiple
core. Helpers skl_dsp_get_core() skl_dsp_put_core() help to
managed the cores.

Many of the power_up/down and DSP APIs take additional argument
of core_id. The primary core, 0 is always powered up first and
then on demand second core.

Subject: ASoC: hdac_hdmi: Increase loglevel of hex dump printed

The hdac_hdmi codec driver prints the ELD information everytime an
external monitor is connected. Make it so that the information is only
printed when someone trying to debug the driver explicitly enables it.

print_hex_dump_bytes (which just calls print_hex_dump) uses
printk(KERN_DEBUG,... which is different from dev_dbg used elsewhere in
the driver: it's always enabled at compile-time. Change it to
print_hex_dump_debug for logging consistency.

Subject: ASoC: intel: Fix sst-dsp dependency on dw stuff

The recent commit [a92ea59b74e2: ASoC: Intel: sst: only select
sst-firmware when DW DMAC is built-in] introduced more strict kconfig
dependency (depends on DW_DMAC_CORE=y) for avoiding the build failures
due to dependency messes in intel-sst.  This makes, however, it
impossible to use this driver with the modularized systems,
i.e. typically on Linux distros.

The problem addressed in the commit above is that sst_dsp_new() and
sst_dsp_free() includes the firmware init / finish that call dw_*()
functions.  Thus building it as built-in with DW_DMAC_CORE module
results in the missing symbols.

However, these sst_dsp functions are basically called only from the
drivers that depend on DW_DMAC_CORE already.  That is, once when these
functions are split out, the rest can be independent from dw stuff.

This patch attempts to solve the issue by the following:
- Split sst-dsp stuff into two modules: snd-soc-sst-dsp and
  snd-soc-sst-firmware.
- Move sst_dsp_new() and sst_dsp_free() to the latter module so that
  the former module can be independent from DW_DMAC_CORE.
- Add a new kconfig SND_SOC_INTEL_SST_FIRMWARE to select the latter
  module by machine drivers.

One only remaining pitfall is that each machine driver has to select
SND_SOC_INTEL_SST_FIRMWARE carefully depending on DW_DMAC_CORE.
This can't be done cleanly due to the restriction of the current
kbuild.

Subject: ASoC: Intel: Skylake: reduce machine name for skl_nau88l25_max98357a

The platform device id table expects names to be less that
20chars, so truncate the name in skl id table and
skl_nau88l25_max98357a machine.

Subject: ASoC: Intel: Fix conflicting pcm dev drvdata on haswell

soc-core sets the snd_soc_pcm_runtime->dev drvdata to
snd_soc_pcm_runtime in soc_post_component_init, and access
it in places like codec_reg_show.

hsw_pcm_open overwrites the drvdata to point to hsw_pcm_data,
confusing soc-core, and causing crashes when cat
/sys/devices/pci0000:00/INT3438:00/.../System PCM/codec_reg

This patch removes the set in hsw_pcm_open since it's no longer
used. commit 7ff9d6714a5c ("ASoC: Intel: Split hsw_pcm_data for
playback and capture") already removed all calls to
snd_soc_pcm_get_drvdata(rtd).

Subject: ASoC: Intel: Skylake: Delete an unnecessary check before the function
 call "release_firmware"

The release_firmware() function tests whether its argument is NULL and then
returns immediately. Thus the test around the call is not needed.

This issue was detected by using the Coccinelle software.
