      ASoC: sh: rz-ssi: Add rz_ssi_set_substream() helper function · 962ff7ec
      Lad Prabhakar authored 
      A copy of substream pointer is stored in priv structure during
rz_ssi_dai_trigger() callback ie in SNDRV_PCM_TRIGGER_START case
and the pointer is assigned to NULL in case of SNDRV_PCM_TRIGGER_STOP.

The driver used the locks only in rz_ssi_stream_is_valid() and assigned
the local substream pointer to NULL in rz_ssi_dai_trigger() callback but
never locked it while making a local copy.

This patch adds the rz_ssi_set_substream() helper function to set the
substream pointer with locks acquired and replaces the instances of
setting the local substream pointer with the rz_ssi_set_substream()
function.

      ASoC: sh: rz-ssi: Use a do-while loop in rz_ssi_pio_recv() · 7276d3f3
      Lad Prabhakar authored 
      Use a do-while loop while reading the samples from RX FIFO. The "done"
flag was only changed as an outcome of the last if-statement (last step)
in this entire procedure. This patch moves the condition from if
statement to while and drops the "done" variable for readability.

While at it, also drop the unneeded parentheses around runtime->dma_area.

      ASoC: add support for TAS5805M digital amplifier · 2e5a74c6
      Mark Brown authored 
      Merge series from Daniel Beer <daniel.beer@igorinstitute.com>:

This pair of patches implements support for the TAS5805M class D audio
amplifier. This driver, and the example configuration in the device-tree
file, were originally based on a 4.19 series kernel and have been
modified slightly from the tested version.

      ASOC: cs42l42: Add support for system suspend · 8f1a27bb
      Mark Brown authored 
      Merge series from Richard Fitzgerald <rf@opensource.cirrus.com>:

Add system suspend and resume handlers so that the cs42l42 is cleanly
put into power-off state during system suspend and the registers are
restored in resume.

      ASoC: fsl-asoc-card: Add optional dt property for setting mclk-id · e6ec5a39
      Mark Brown authored 
      Merge series from Ariel D'Alessandro <ariel.dalessandro@collabora.com>:

Sound cards may allow using different main clock inputs. In the generic
fsl-asoc-card driver, these values are hardcoded for each specific card
configuration.  Let's make it more flexible, allowing setting mclk-id
from the device-tree node.

      ASoC: Xilinx fixes · 8bcd0f12
      Mark Brown authored 
      Merge series from Robert Hancock <robert.hancock@calian.com>:

There are drivers in mainline for the Xilinx Audio Formatter and Xilinx
I2S IP cores. However, because of a few issues, these were only really
usable with Xilinx's xlnx_pl_snd_card top-level driver, which is not in
mainline (and not suitable for mainline).

The fixes in this patchset, for the simple-card layer as well as the
Xilinx drivers, now allow these drivers to be properly used with
simple-card without any out-of-tree support code.

      ASoC: SOF: Intel: don't download firmware at each resume · 01f5060e
      Mark Brown authored 
      Merge series from Pierre-Louis Bossart <pierre-louis.bossart@linux.intel.com>:

After the first firmware boot, the firmware is capable of
saving/restoring its context to/from IMR (Isolated Memory Region, set
aside by BIOS on startup). This capability improves the resume speed.

Due to an unexplained issue on Up2 boards, this capability is disabled
on ApolloLake.

For backwards compatibility, the regular boot flow is used with older
firmware. For added peace of mind, a kernel module parameter is
provided to force the regular boot flow - this shouldn't be necessary
since we've been testing these patches for 6+ months.

      ASoC: topology: Fixes · cef982dc
      Mark Brown authored 
      Merge series from Amadeusz Sławiński <amadeuszx.slawinski@linux.intel.com>:

Following series performs few cleanups in topology code.

First patch reduces number of prints we get from failure.
Second allos TLV controls to be either read or write which should be
possible as evidenced by further code in function.
Last one cleanups after refactoring of memory handling.

v2:
 - Add missing Fixes tag on second patch
 - Add Reviewed-by tag from Pierre

Amadeusz Sławiński (3):
  ASoC: topology: Remove superfluous error prints
  ASoC: topology: Allow TLV control to be either read or write
  ASoC: topology: Optimize soc_tplg_dapm_graph_elems_load behavior
