[PATCH 1/7] ASoC: SOF: Intel: hda: report error only for the last ROM init iteration

[Ranjani Sridharan]

The FW boot sequence includes multiple attempts for ROM init.
When it does take more than one attempt, we should not log the
errors encountered during the failed attempts and only log them
during the final iteration.

[PATCH 2/7] ASoC: SOF: fix a runtime pm issue in SOF when HDMI codec doesn't work

[Ranjani Sridharan]

From: Rander Wang <rander.wang@intel.com>

When hda_codec_probe() doesn't initialize audio component, we disable
the codec and keep going. However,the resources are not released. The
child_count of SOF device is increased in snd_hdac_ext_bus_device_init
but is not decrease in error case, so SOF can't get suspended.

snd_hdac_ext_bus_device_exit will be invoked in HDA framework if it
gets a error. Now copy this behavior to release resources and decrease
SOF device child_count to release SOF device.

[PATCH 3/7] ASoC: SOF: intel: hda: support also devices with 1 and 3 dmics

[Ranjani Sridharan]

From: Jaska Uimonen <jaska.uimonen@linux.intel.com>

Currently the dmic check code supports only devices with 2 or 4 dmics.
With other dmic counts the function will return 0. Lately we've seen
devices with only 1 dmic thus enable also configurations with 1, and
possibly 3, dmics. Add also topology postfix -1ch and -3ch for new dmic
configuration.

[PATCH 4/7] ASoC: SOF: topology: fix the ipc_size calculation for process component

[Ranjani Sridharan]

From: Keyon Jie <yang.jie@linux.intel.com>

The topology private struct is used for token parsing and its size
should not be included to the ipc_size, fix it here though it didn't
cause any real issue as the Firmware won't use this wrong-added data.

[PATCH 7/7] ASoC: SOF: sof-of-dev: Add .arch_ops field

[Ranjani Sridharan]

From: Iulian Olaru <iulianolaru249@yahoo.com>

Add .arch_ops field in the sof_imx8x_ops structure.
The inclusion of this field will allow the usage of functions from
sof/core.c in order to print debug information such as the registers and
a stack dump in case of a firmware ops.

The SND_SOC_SOF_XTENSA is added in the imx/Kconfig file so the compilation
is successful.

All being well this means that it will be integrated into the linux-next
tree (usually sometime in the next 24 hours) and sent to Linus during
the next merge window (or sooner if it is a bug fix), however if
problems are discovered then the patch may be dropped or reverted.

You may get further e-mails resulting from automated or manual testing
and review of the tree, please engage with people reporting problems and
send followup patches addressing any issues that are reported if needed.

If any updates are required or you are submitting further changes they
should be sent as incremental updates against current git, existing
patches will not be replaced.

Please add any relevant lists and maintainers to the CCs when replying
to this mail.

Thanks,
Mark

we now have multiple reports of devices with a single microphone where 
audio is broken without this patch, e.g. 
https://github.com/thesofproject/linux/issues/2451

This patch should be applied to -stable versions all the way to 5.6. It 
would be desirable for 5.5 and 5.4 as well but it will not apply 
cleanly. It's be trivial to provide a modified patch for these earlier 
kernel versions but I don't know what the process might be here?

Send a backport to Greg & stable with a note explaining what's going on.
