ASoC: Updates for v4.18

This is a very big update, mainly due to a huge set of new drivers some
of which are individually very large.  We also have a lot of fixes for
the topology stuff, several of the users have stepped up and fixed some
the serious issues there, and continued progress on the transition away
from CODEC specific drivers to generic component drivers.

 - Many fixes for the topology code, including fixes for the half done
   v4 ABI compatibility from Guenter Roeck and other ABI fixes from
   Kirill Marinushkin.
 - Lots of cleanup for Intel platforms based on Realtek CODECs from Hans
   de Goode.
 - More followups on removing legacy CODEC things and transitioning to
   components from Morimoto-san.
 - Conversion of OMAP DMA to the new, more standard SDMA-PCM driver.
 - A series of fixes and updates to the rather elderly Cirrus Logic SoC
   drivers from Alexander Sverdlin.
 - Qualcomm DSP support from Srinivas Kandagatla.
 - New drivers for Analog SSM2305, Atmel I2S controllers, Mediatek
   MT6351, MT6797 and MT7622, Qualcomm DSPs, Realtek RT1305, RT1306 and
   RT5668 and TI TSCS454

      ASoC: topology: Move skl-tplg-interface.h to uapi · 0c24fdc0
      Guenter Roeck authored 
      skl-tplg-interface.h describes firmware format details for Skylake
topology files. It is part of the ABI and should reside in the uapi
directory.

While moving the file, also replace the license boilerplate with
the SPDX License Identifier.

No functional change.

      ASoC: topology: Improve backwards compatibility with v4 topology files · ac9391da
      Guenter Roeck authored 
      Commit dc31e741 ("ASoC: topology: ABI - Add the types for BE
DAI") introduced sound topology files version 5. Initially, this
change made the topology code incompatible with v4 topology files.
Backwards compatibility with v4 configuration files was
subsequently added with commit 288b8da7 ("ASoC: topology:
Support topology file of ABI v4").

Unfortunately, backwards compatibility was never fully implemented.

First, the manifest size in (Skylake) v4 configuration files is set
to 0, which causes manifest_new_ver() to bail out with error messages
similar to the following.

snd_soc_skl 0000:00:1f.3: ASoC: invalid manifest size
snd_soc_skl 0000:00:1f.3: tplg component load failed-22
snd_soc_skl 0000:00:1f.3: Failed to init topology!
snd_soc_skl 0000:00:1f.3: ASoC: failed to probe component -22
skl_n88l25_m98357a skl_n88l25_m98357a: ASoC: failed to instantiate card -22
skl_n88l25_m98357a: probe of skl_n88l25_m98357a failed with error -22

After this problem is fixed, the following error message is seen instead.

snd_soc_skl 0000:00:1f.3: ASoC: old version of manifest
snd_soc_skl 0000:00:1f.3: Invalid descriptor token 1093938482
snd_soc_skl 0000:00:1f.3: ASoC: failed to load widget media0_in cpr 0
snd_soc_skl 0000:00:1f.3: tPlg component load failed-22

This message is seen because backwards compatibility for loading widgets
was never implemented.

The lack of audio support when running the upstream kernel on recent
Chromebooks has been reported in various forums, and can be traced back
to this problem. Attempts to fix the problem, usually by providing v5
configuration files, were only partially successful.

Let's implement backward compatibility properly to solve the problem
for good.

      Ben Hutchings authored 
      sound/pci/hda/local.h seems to be an earlier version of
sound/hda/local.h; it was added at the same time but doesn't seem to
have ever been used (within the git history).  Most of its macros
depend on a hdac_read_parm() function which is not defined anywhere.

      ASoC: Intel: kbl: Move codec sysclk config to codec_init function · 56c3a953
      Mac Chiang authored 
      On APL, commit fd0f2375
("ASoC: Intel: bxt: Move codec sysclk config to codec_init function")
fixed an issue related to jack detection.

The MCLK for DA7219 does not change in this platform, but is
currently being configured everytime as part of the platform_clock
event handler for DAPM. The upshot of this is that we have
unnecessary calls to this function, and it also means that if
a stream hasn't yet been started, DA7219 driver does not have the
correct MCLK rates programmed and so the HP detection feature does
not operate as expected.

The same fix is needed on KBL.

This patch rectifies this issue by moving the sysclk call to
codec_init function so it's only called once at initialisation.

      ASoC: simple-card: set cpu dai clk in hw_params · e9be4ffd
      Daniel Mack authored 
      The simple-card driver currently accepts a clock node in the cpu dai
sub-node and only uses it as an alternative to the
'system-clock-frequency' property to get the current frequency.

This patch adds another use of the passed clock node. If mclk-fs is
specified, the clocks in cpu and codec dai sub-nodes will be set to
the calculated rate (stream rate * mclk_fs) in hw_params.

This allows platforms to pass tuneable clocks as phandle that will
automatically be set to the right rates.

      ALSA: hda - Handle kzalloc() failure in snd_hda_attach_pcm_stream() · a3aa60d5
      Bo Chen authored 
      When 'kzalloc()' fails in 'snd_hda_attach_pcm_stream()', a new pcm instance is
created without setting its operators via 'snd_pcm_set_ops()'. Following
operations on the new pcm instance can trigger kernel null pointer dereferences
and cause kernel oops.

This bug was found with my work on building a gray-box fault-injection tool for
linux-kernel-module binaries. A kernel null pointer dereference was confirmed
from line 'substream->ops->open()' in function 'snd_pcm_open_substream()' in
file 'sound/core/pcm_native.c'.

This patch fixes the bug by calling 'snd_device_free()' in the error handling
path of 'kzalloc()', which removes the new pcm instance from the snd card before
returns with an error code.
