5ae5c3f9f4 ASoC: qcom: fix QDSP6 dependencies, attempt #3
[ Upstream commit b1b8eb1283c90a953089d988930d7b6156418958 ]

The previous fix left another warning in randconfig builds:

WARNING: unmet direct dependencies detected for SND_SOC_QDSP6
  Depends on [n]: SOUND [=y] && !UML && SND [=y] && SND_SOC [=y] && SND_SOC_QCOM [=y] && QCOM_APR [=y] && COMMON_CLK [=n]

54919a7153 ASoC: q6afe-clocks: Add missing parent clock rate
[ Upstream commit 7e20ae1208daaf6dad85c2dcb968fc590b6f3b99 ]

setting clock rate on child clocks without a parent clock rate will
result in zero clk rate for child. This also means that when audio
is started dsp will attempt to access registers without enabling
clock resulting in board boot up.

Fix this by adding the missing parent clock rate.

468b3a1ab2 ASoC: qcom: common: Fix refcounting in qcom_snd_parse_of()
[ Upstream commit 4e59dd249cd513a211e2ecce2cb31f4e29a5ce5b ]

There are two issues in this function.

1) We can't drop the refrences on "cpu", "codec" and "platform" before
   we take the reference.  This doesn't cause a problem on the first
   iteration because those pointers start as NULL so the of_node_put()
   is a no-op.  But on the subsequent iterations, it will lead to a use
   after free.

2) If the devm_kzalloc() allocation failed then the code returned
   directly instead of cleaning up.

[ Upstream commit bcc96dc3cf8048c80af7c487af17e19be27ac57d ]

The check for an error return from the call to snd_pcm_format_width

zero. Fix this by making bitwidth an int.

ASoC: qcom: sdm845: set driver name correctly
With the current state of code, we would endup with something like
below in /proc/asound/cards for 2 machines based on this driver.

Machine 1:
 0 [DB845c            ]: DB845c - DB845c
                       DB845c
Machine 2:
 0 [LenovoYOGAC6301]: Lenovo-YOGA-C63 - Lenovo-YOGA-C630-13Q50
                     LENOVO-81JL-LenovoYOGAC630_13Q50-LNVNB161216

This is not very UCM friendly both w.r.t to common up configs and
card identification, and UCM2 became totally not usefull with just
one ucm sdm845.conf for two machines which have different setups
w.r.t HDMI and other dais.

Reasons for such thing is partly because Qualcomm machine drivers never
cared to set driver_name.

This patch sets up driver name for the this driver to sort out the
UCM integration issues!

after this patch contents of /proc/asound/cards:

Machine 1:
 0 [DB845c         ]: sdm845 - DB845c
                      DB845c
Machine 2:
 0 [LenovoYOGAC6301]: sdm845 - Lenovo-YOGA-C630-13Q50
                     LENOVO-81JL-LenovoYOGAC630_13Q50-LNVNB161216

with this its possible to align with what UCM2 expects and we can have
sdm845/DB845.conf
sdm845/LENOVO-81JL-LenovoYOGAC630_13Q50-LNVNB161216.conf
... for board variants. This should scale much better!

Previously there was no case where we need to set clock or send commands
that are not associated with q6afe ports, now we have cases like clock
voting and clock consumers like codecs that needed these clocks.

update q6afe_set_param() to support such cases, including token passing.

ASoC: qcom: common: Parse auxiliary devices from device tree
In some cases we need to probe additional audio components that do
not appear as part of the DAI links specified in the device tree.
Examples for this are auxiliary devices such as analog amplifiers
or codecs.

The ASoC core provides a way to probe these components by adding
them to snd_soc_card->aux_dev. We can use the snd_soc_of_parse_aux_devs()
function to parse them from the device tree.

As an example for this, some MSM8916 smartphones have an analog
speaker amplifier connected to the HPHR output. With the new property
this can be modelled as follows:

	speaker-amp: audio-amplifier {
		compatible = "simple-audio-amplifier";
		enable-gpios = <&msmgpio 114 GPIO_ACTIVE_HIGH>;
		sound-name-prefix = "Speaker Amp";
	};

	&sound {
		aux-devs = <&speaker_amp>;
		audio-routing = "Speaker Amp IN", "HPHR";
	};

Merge series "ASoC: qdsp6: add gapless compressed audio support" from Srinivas Kandagatla <srinivas.kandagatla@linaro.org>:
This patchset adds gapless compressed audio support on q6asm.
Gapless on q6asm is implemented using 2 streams in a single q6asm session.

First few patches such as stream id per each command, gapless flags
and silence meta data are for preparedness for adding gapless support.
Last patch implements copy callback to allow finer control over buffer offsets,
specially in partial drain cases.

This patchset is tested on RB3 aka DB845c platform.

This patchset as it is will support gapless however QDSP can also
support switching decoders on a single stream. Patches to support such feature
are send in different patchset which involves adding generic interfaces.

Thanks,
srini

Changes since v2:(mostly suggested by Pierre)
- removed unnessary kernel style comments,
- moved TIMESTAMP flag to respective patch.
- move preparatory code from gapless support patch to new one.
- fix subject prefix of one patch.
- add comments to clarify valid stream_ids

ASoC: q6asm: make commands specific to streams
Each ASM session can have multiple streams attached to it,
current design was to allow only one static stream id 1 per each session.
However for use-case like gapless, we would need 2 streams to open per session.

This patch converts all the q6asm apis to take stream id as argument
to allow multiple streams to open on a single session, This is useful
for gapless playback cases.

Now the dai driver can specify which stream id for each command.
