The device tree binding declares the ti,mic-bias-source and the
ti,vref-source properties as u32.  The code reads them as u8 which is
incorrect.  Since the device tree binding indicates them as u32 the
conde needs to be updated to read u32.

In addition the bias source needs to be shifted 4 bits to
correctly write the register.

Simultaneous capture on dmic and headset mic is having
issue with high hw_level being reported.

Issue Can be reproduced by:
arecord -D hw:2,0 -f dat -d 60 /tmp/test0 &
arecord -D hw:2,2 -f dat -d 60 /tmp/test1 &
cat /proc/asound/card2/pcm?c/sub0/status

Actual issue is :
When we open one capture stream on one instance lets say I2S_SP and then
once again if we open other capture on other instance lets say I2S_BT while
first capture is in progress and when we try to read the status of both
running instances by below command cat /proc/asound/card2/pcm?c/sub0/status
we observe that avail_max is being doubled on first opened
capture(I2S_SP in the example).

This is because our previous implementation was like when any instance is
opened it gets initialized in dma_open irrespective of on what instance it
called open.

For example:
First I2S_SP called opened it initializes both SP/BT capture streams
irrespective of on which instance the stream opened.next time I2S_BT
called opened and it initializes both SP/BT this corrupts the behaviour .

So with this patch the stream gets initialized only on specific instance
when ever it gets opened calls hw_params.

This rectifies the issue.

davinci_mcasp_get_dma_type() invokes dma_request_chan(), which returns a
reference of the specified dma_chan object to "chan" with increased
refcnt.

When davinci_mcasp_get_dma_type() returns, local variable "chan" becomes
invalid, so the refcount should be decreased to keep refcount balanced.

The reference counting issue happens in one exception handling path of
davinci_mcasp_get_dma_type(). When chan device is NULL, the function
forgets to decrease the refcnt increased by dma_request_chan(), causing
a refcnt leak.

Previously CLOCKING2 is set as a volatile register, but cause
issue at suspend & resume, that some bits of CLOCKING2 is not
restored at resume, for example SYSCLK_SRC bits, then the output
clock is wrong.

The volatile property is caused by CLASSD_CLK_DIV bits,
which are controlled by the chip itself. But the datasheet
claims these are read only and protected by the security key,
and they are not read by the driver at all.

So it should be safe to change CLOCKING2 to be non-volatile.

Merge tag 'tegra-for-5.7-asoc' of git://git.kernel.org/pub/scm/linux/kernel/git/tegra/linux into asoc-5.7

ASoC: tegra: Fixes for v5.7-rc3

This contains a couple of fixes that are needed to properly reconfigure
the audio clocks on older Tegra devices.

Tegra PMC clock clk_out_1 is dedicated for audio mclk from Tegra30
through Tegra210 and currently Tegra clock driver keeps the audio mclk
enabled.

With the move of PMC clocks from clock driver into pmc driver, audio
mclk enable from clock driver is removed and this should be taken care
of by the audio driver.

tegra_asoc_utils_init() calls tegra_asoc_utils_set_rate() and audio mclk
rate configuration is not needed during init and the rate is actually
set during the ->hw_params() callback.

So, this patch removes tegra_asoc_utils_set_rate() call and just leaves
the audio mclk enabled.

Fix rsnd_dai_call() operations being performed twice for the master SSI
in multi-SSI setups, and fix the rsnd_ssi_stop operation for multi-SSI

The only visible effect of these issues was some "status check failed"
spam when the rsnd_ssi_stop was called, but overall the code is cleaner
now, and some questionable writes to the SSICR register which did not
lead to any observable misbehaviour but were contrary to the datasheet
are fixed.

Mark:

effect in a simpler fashion, if you would prefer a clean patch series

snd_soc_dapm_kcontrol widget which is created by autodisable control

		mask |= w->mask << w->shift;
		if (w->power)
			value |= w->on_val << w->shift;
		else
			value |= w->off_val << w->shift;

Shift on the mask in dapm_kcontrol_data_alloc() is removed to prevent
double shift.

Fix the rsnd_ssi_stop function to skip disabling the individual SSIs of
a multi-SSI setup, as the actual stop is performed by rsnd_ssiu_stop_gen2
- the same logic as in rsnd_ssi_start. The attempt to disable these SSIs
was harmless, but caused a "status check failed" message to be printed
for every SSI in the multi-SSI setup.
The disabling of interrupts is still performed, as they are enabled for
all SSIs in rsnd_ssi_init, but care is taken to not accidentally set the
EN bit for an SSI where it was not set by rsnd_ssi_start.

The master SSI of a multi-SSI setup was attached both to the
RSND_MOD_SSI slot and the RSND_MOD_SSIP slot of the rsnd_dai_stream.
This is not correct wrt. the meaning of being "parent" in the rest of
the SSI code, where it seems to indicate an SSI that provides clock and
word sync but is not transmitting/receiving audio data.

Not treating the multi-SSI master as parent allows removal of various
special cases to the rsnd_ssi_is_parent conditions introduced in commit
a09fb3f2 ("ASoC: rsnd: Fix parent SSI start/stop in multi-SSI mode").
It also fixes the issue that operations performed via rsnd_dai_call()
were performed twice for the master SSI. This caused some "status check
failed" spam when stopping a multi-SSI stream as the driver attempted to
stop the master SSI twice.

While initiliazing the links, ASoC treats the codec-to-codec links of this
card type as a DPCM backend. This error eventually leads to the Oops.

Most of the card driver code is shared between DPCM backends and
codec-to-codec links. The property "no_pcm" marking DCPM BE was left set on
codec-to-codec links, leading to this problem. This commit fixes that.

Major regressions were detected by SOF CI on CherryTrail and Broadwell:

[   25.705750]  SSP2-Codec: ASoC: no backend playback stream
[   27.923378]  SSP2-Codec: ASoC: no users playback at close - state

This is root-caused to the introduction of the DAI capability checks
with snd_soc_dai_stream_valid(). Its use in soc-pcm.c makes it a
requirement for all DAIs to report at least a non-zero min_channels
field.

For some reason the SSP structures used for SKL+ did provide this
information but legacy platforms didn't.

Merge series "ASoC: rsnd: Fixes for multichannel HDMI audio output" from Matthias Blankertz <matthias.blankertz@cetitec.com>:

This fixes two issues in the snd-soc-rcar driver blocking multichannel
HDMI audio out: The parent SSI in a multi-SSI configuration is not
correctly set up and started, and the SSI->HDMI channel mapping is
wrong.

With these patches, the following device tree snippet can be used on an
r8a7795-based platform (Salvator-X) to enable multichannel HDMI audio on
HDMI0:

rsnd_port1: port@1 {
	rsnd_endpoint1: endpoint {
		remote-endpoint = <&dw_hdmi0_snd_in>;

		dai-format = "i2s";
		bitclock-master = <&rsnd_endpoint1>;
		frame-master = <&rsnd_endpoint1>;

		playback = <&ssi0 &ssi1 &ssi2 &ssi9>;
	};
};

With a capable receiver attached, all of 2ch (stereo), 6ch (e.g. 5.1)
and 8ch audio output should work.

If we don't find any pcm, pcm will point at address at an offset from
the the list head and not a meaningful structure. Fix this by returning
correct pcm if found and NULL if not. Found with coccinelle.

The HDMI?_SEL register maps up to four stereo SSI data lanes onto the
sdata[0..3] inputs of the HDMI output block. The upper half of the
register contains four blocks of 4 bits, with the most significant
controlling the sdata3 line and the least significant the sdata0 line.

The shift calculation has an off-by-one error, causing the parent SSI to
be mapped to sdata3, the first multi-SSI child to sdata0 and so forth.
As the parent SSI transmits the stereo L/R channels, and the HDMI core
expects it on the sdata0 line, this causes no audio to be output when
playing stereo audio on a multichannel capable HDMI out, and
multichannel audio has permutated channels.

Fix the shift calculation to map the parent SSI to sdata0, the first
child to sdata1 etc.

The parent SSI of a multi-SSI setup must be fully setup, started and
stopped since it is also part of the playback/capture setup. So only
skip the SSI (as per commit 203cdf51 ("ASoC: rsnd: SSI parent cares
SWSP bit") and commit 597b046f ("ASoC: rsnd: control SSICR::EN
correctly")) if the SSI is parent outside of a multi-SSI setup.

Commit b56be800 ("ASoC: soc-pcm: call
snd_soc_dai_startup()/shutdown() once") was the initial problematic
commit.

Commit 1ba616bd ("ASoC: soc-dai: fix DAI startup/shutdown sequence")
was an attempt to fix things but it does not work on Baytrail,
reverting all changes seems necessary for now.
