      Yong Zhi authored 
      In commit d696a614 ("ASoC: rt1015: Add condition to prevent SoC
providing bclk in ratio of 50 times of sample rate."), PLL input at 50fs
is no longer supported, the new recommended settings at 48Khz rate are:

PLL input       SSP bclk
------------------------
64fs            3.073Mhz
100fs           4.8Mhz

(bclk update is reflected in topoplogy.)

      ASoC: Intel: sof_sdw: avoid crash if invalid DSP topology loaded · 6b540ac7
      Kai Vehmanen authored 
      The mc_private->hdmi_pcm_list is populated by elements loaded during
DSP topology load. Valid topologies for this machine driver will always
have PCM nodes for HDMI, but driver should fail gracefully even in the case
this is not true. Add a sanity check to sof_sdw_hdmi_card_late_probe()
for this case. Without the fix, a null pcm handle gets dereferenced.

      Kai Vehmanen authored 
      Extend the generic SOF Soundwire machine driver to support systems where
iDisp HDMI/DP audio codec is disabled for some reason (i915 driver
disabled, HDMI/DP implemented with a discrete GPU, etc). Switch codecs
to SoC dummy in the affected DAI links. This allows to reuse existing
topologies for this case.

      ASoC: Intel: sof_sdw_rt711: remove properties in card remove · cf0418cd
      Pierre-Louis Bossart authored 
      The rt711 jack detection properties are set from the machine drivers
during the card probe, as done in other ASoC examples.

KASAN reports a use-after-free error when unbinding drivers due to a
confusing sequence between the ACPI core, the device core and the
SoundWire device cleanups.

Rather than fixing this sequence, follow the recommendation to have
the same caller add and remove properties, add an explicit
device_remove_properties() in the card .remove() callback.

In future patches the use of device_add/remove_properties will be
replaced by a direct handling of a swnode, but the sequence will
remain the same.

      Merge series "Add ASoC AHUB components for Tegra210 and later" from Sameer Pujar <spujar@nvidia.com>:

Overview
========
Audio Processing Engine (APE) comprises of Audio DMA (ADMA) and Audio
Hub (AHUB) unit. AHUB is a collection of hardware accelerators for audio
pre-processing and post-processing. It also includes a programmable full
crossbar for routing audio data across these accelerators.

This series exposes some of these below mentioned HW devices as ASoC
components for Tegra platforms from Tegra210 onwards.
 * ADMAIF : The interface between ADMA and AHUB
 * XBAR   : Crossbar for routing audio samples across various modules
 * I2S    : Inter-IC Sound Controller
 * DMIC   : Digital Microphone
 * DSPK   : Digital Speaker

Following is the summary of current series.
 * Add YAML DT binding documentation for above mentioned modules.
 * Helper function for ACIF programming is exposed for Tegra210 and later.
 * Add ASoC driver components for each of the above modules.
 * Build ACONNECT and ADMA drivers which are essential to realize audio
   use case.
 * Add DT entries for above components for Tegra210, Tegra186 and
   Tegra194.

As per the suggestion in [0] audio graph based sound card support
is pushed in a separate series.

[0] https://lkml.org/lkml/2020/6/27/4

Changelog
=========

v4 -> v5
--------
 * Common changes
   - simple-card driver changes are dropped. Changes are migrated to audio
     graph card and are moved to a separate series as suggested.

   - '#sound-dai-cells' property is not needed for planned audio graph card
     Hence dropped from documentation and related DT binding of component
     drivers.

   - CIF and DAP DAIs are added for I/O drivers (DMIC, DSPK, I2S) to
     represent DAI links using audio graph card. Similary DAIs are added in
     AHUB driver to describe endpoints in audio crossbar. Routing is updated
     to reflect the same in drivers.

      ASoC: tegra: Add Tegra186 based DSPK driver · 327ef647
      Sameer Pujar authored 
      The Digital Speaker Controller (DSPK) converts the multi-bit Pulse Code
Modulation (PCM) audio input to oversampled 1-bit Pulse Density Modulation
(PDM) output. From the signal flow perpsective, the DSPK can be viewed as
a PDM transmitter that up-samples the input to the desired sampling rate
by interpolation then converts the oversampled PCM input to the desired
1-bit output via Delta Sigma Modulation (DSM).

This patch registers DSPK component with ASoC framework. The component
driver exposes DAPM widgets, routes and kcontrols for the device. The DAI
driver exposes DSPK interfaces, which can be used to connect different
components in the ASoC layer. Makefile and Kconfig support is added to
allow to build the driver. The DSPK devices can be enabled in the DT via
"nvidia,tegra186-dspk" compatible binding. This driver can be used
on Tegra194 chip as well.

      ASoC: tegra: Add Tegra210 based AHUB driver · 16e1bcc2
      Sameer Pujar authored 
      The Audio Hub (AHUB) comprises a collection of hardware accelerators for
audio pre/post-processing and a programmable full crossbar (XBAR) for
routing audio data across these accelerators in time and in parallel.
AHUB supports multiple interfaces to I2S, DSPK, DMIC etc., XBAR is a
switch used to configure or modify audio routing between HW accelerators
present inside AHUB.

This patch registers AHUB component with ASoC framework. The component
driver exposes DAPM widgets, routes and kcontrols for the device. The DAI
driver exposes AHUB interfaces, which can be used to connect different
components in the ASoC layer. Currently the driver takes care of XBAR
programming to allow audio data flow through various clients of the AHUB.
Makefile and Kconfig support is added to allow to build the driver. The
AHUB component can be enabled in the DT via below compatible bindings.
  - "nvidia,tegra210-ahub" for Tegra210
  - "nvidia,tegra186-ahub" for Tegra186 and Tegra194

      ASoC: tegra: Add Tegra210 based I2S driver · c0bfa983
      Sameer Pujar authored 
      The Inter-IC Sound (I2S) controller implements full-duplex, bi-directional
and single direction point to point serial interface. It can interface
with I2S compatible devices. Tegra I2S controller can operate as both
master and slave.

This patch registers I2S controller with ASoC framework. The component
driver exposes DAPM widgets, routes and kcontrols for the device. The DAI
driver exposes I2S interfaces, which can be used to connect different
components in the ASoC layer. Makefile and Kconfig support is added to
allow to build the driver. The I2S devices can be enabled in the DT via
"nvidia,tegra210-i2s" compatible binding.

      ASoC: tegra: Add Tegra210 based DMIC driver · 8c8ff982
      Sameer Pujar authored 
      The Digital MIC (DMIC) Controller is used to interface with Pulse Density
Modulation (PDM) input devices. The DMIC controller implements a converter
to convert PDM signals to Pulse Code Modulation (PCM) signals. From signal
flow perspective, the DMIC can be viewed as a PDM receiver.

This patch registers DMIC component with ASoC framework. The component
driver exposes DAPM widgets, routes and kcontrols for the device. The DAI
driver exposes DMIC interfaces, which can be used to connect different
components in the ASoC layer. Makefile and Kconfig support is added to
allow to build the driver. The DMIC devices can be enabled in the DT via
"nvidia,tegra210-dmic" compatible string. This driver can be used for
Tegra186 and Tegra194 chips as well.

      ASoC: tegra: Add support for CIF programming · 1c3b89fb
      Sameer Pujar authored 
      Audio Client Interface (CIF) is a proprietary interface employed to route
audio samples through Audio Hub (AHUB) components by inter connecting the
various modules.

This patch exports an inline function tegra_set_cif() which can be used,
for now, to program CIF on Tegra210 and later Tegra generations. Later it
can be extended to include helpers for legacy chips as well.
