7ba236ce58 ASoC: add Component level set_bias_level
In current ALSA SoC, Codec only has set_bias_level feature.
Codec will be merged into Component in next generation ALSA SoC,
thus current Codec specific feature need to be merged into it.
This is glue patch for it.

Codec driver has .idle_bias_off for dapm bias. But Component
driver doesn't have it, and dapm->idle_bias_off is set as "true".
To keep compatibility, this patch adds "idle_bias_on" instead of
".idle_bias_off" on Component driver.
dapm->idle_bias_off will be set by inverted idle_bias_on.

When we replace Codec to Component, the driver which has
".idle_bias_off = true" is just remove it,
and the driver which doesn't have it will have new
".idle_bias_on = true".

f523acebbb ASoC: add Component level pcm_new/pcm_free v2
In current ALSA SoC, Platform only has pcm_new/pcm_free feature,
but it should be supported on Component level. This patch adds it.

The v1 was added commit 99b04f4c4051f7 ("ASoC: add Component level
pcm_new/pcm_free") but it called all "card" connected component's
pcm_new/free, it was wrong.
This patch calls "rtd" connected component.

5d61f0ba65 ASoC: pcm: Sync delayed work before releasing resources
When ASoC driver is unbound dynamically during its operation (i.e. a
kind of hot-unplug), we may hit Oops due to the resource access after
the release by a delayed work, something like:

  Unable to handle kernel paging request at virtual address dead000000000220
  ....
  PC is at soc_dapm_dai_stream_event.isra.14+0x20/0xd0
  LR is at snd_soc_dapm_stream_event+0x74/0xa8
  ....
  [<ffff000008715610>] soc_dapm_dai_stream_event.isra.14+0x20/0xd0
  [<ffff00000871989c>] snd_soc_dapm_stream_event+0x74/0xa8
  [<ffff00000871b23c>] close_delayed_work+0x3c/0x50

  [<ffff0000080c201c>] kthread+0xfc/0x128
  [<ffff0000080842f0>] ret_from_fork+0x10/0x18

For fixing the race, this patch adds a sync-point in pcm private_free
callback to finish the delayed work before actually releasing the
resources.

d24e95f875 ASoC: wm8998: Correct handling of input muxes
Currently, wm8998 has two input mux controls on IN1 and attempts to
switch these together when the A position is configured to be in digital
mode. This is because the digital mode requires pins from both the L and
R channels. However, this doesn't work as intended because whilst the
registers on the chip are changed the corresponding DAPM
representation is only updated for the mux actually being changed by the
user. The DAPM graph being out of sync with the hardware can cause some
odd issues with incorrect things being powered etc.

To avoid this issue and simplify the code somewhat, simply let the user
set the muxes as they desire. If they set an invalid configuration they
might not get audio from the DMIC but most of the chip requires you to
set a valid audio route to get audio.

81cb71240e ASoC: rsnd: add rsnd_dma_alloc()
R-Car sound DMA will be used from SSI/SRC.
dma.c doesn't alloc DMA handler in .probe timing, because we don't
know what kind of DMA transfer will be used then.
Thus, SSI/SRC have *rsnd_mod for DMA. rsnd_dma_attach() will allocate
it and attach it to system.
It will be PIO mode if it can't alloc DMA handler.

In case of MIX is used, rsnd_dma_attach() will be called twice from SSI.
To avoid duplicate allocation, current rsnd_dma_attach() is checking
allocated DMA handler. This DMA related operation is a little bit
difficult to understand.
This patch adds new rsnd_dma_alloc() and separates allocation and attach
for readable code.

957ce0c6b8 ASoC: soc-pcm: check symmetry after hw_params
hw_params may be fixup by be_hw_params_fixup, calling
soc_pcm_params_symmetry() before hw_params will have issue
if there is hw_params changes in be_hw_params_fixup.

For example, with following use case
1. a dai-link which is able to convert sample rate on BE side
2. set BE playback and capture sample rate to 44100Hz
3. play a 48000Hz audio stream with this dai-link
4. record from this dai-link with 44100Hz sample rate

Got following error message when record starts
[  495.013527]  be_link_ak4613: ASoC: unmatched rate symmetry: 48000 - 44100
[  495.021729]  be_link_ak4613: ASoC: hw_params BE failed -22
[  495.028589]  rsnd_link0: ASoC: hw_params BE failed -22

Because in soc_pcm_hw_params(), FE rate is still having value before
it is fixup by be_hw_params_fixup(), when soc_pcm_params_symmetry() checks
symmetry, thus soc_pcm_params_symmetry() complains about the unmatched rate
between the active stream and the new stream tries to start.

This patch moves soc_pcm_params_symmetry() after hw_params to resolve the
above issue.

5a5d718f95 ALSA: hda - program ICT bits to support HBR audio
On recent Intel platforms (Haswell, Broadwell, Skylake, ApolloLake,
KabyLake, ...), the IEC Coding Type (ICT) bitfield in the Digital
Converter Control #3 needs to be set explicitly for HDMI/DisplayPort
High Bit Rate (HBR) audio playback to work. This was not required in
earlier platforms when HBR was first introduced. The ICT bits are
defined in Section 7.3.3.9 of the HDaudio 1.0a specification.

Since the ICT bitfield was not specified for HDAudio 1.0 devices
(before 2009), we only program it on machines more recent than
Haswell.

We tested that this fix is not needed on Baytrail-I (MinnowBoard
Turbot) and believe by extension it also does not apply to Braswell.

e1af344df4 ALSA: asihpi: fix a potential double-fetch bug when copying puhm
The hm->h.size is intended to hold the actual size of the hm struct
that is copied from userspace and should always be <= sizeof(*hm).

However, after copy_from_user(hm, puhm, hm->h.size), since userspace
process has full control over the memory region pointed by puhm, it is
possible that the value of hm->h.size is different from what is fetched-in
previously (get_user(hm->h.size, (u16 __user *)puhm)). In other words,
hm->h.size is overriden and the relation between hm->h.size and the hm
struct is broken.

This patch proposes to use a seperate variable, msg_size, to hold
the value of the first fetch and override hm->h.size to msg_size
after the second fetch to maintain the relation.

devm_gpiod_get is called with GPIOF_OUT_INIT_LOW but the function doesn't
allow the parameters. Unluckily, GPIOF_OUT_INIT_LOW is same value as
GPIOD_ASIS and gpio direction isn't set properly.

Muted stream comes up when I try recording some sounds on TM2. mic-bias
gpiod state can't be changed because the gpiod is created with the invalid
parameter. The gpio should be set GPIOD_OUT_HIGH.

e8d9320890 ASoC: samsung: Use 'samsung-i2s' cpu_dai for dai_links
Add specific cpu_dai_name to dai_link because samsung i2s driver registers
two dais and components. Selecting one of them clearly is needed more
information like cpu_dai_name, of_node. The reason why the dai_links have
to use 'samsung-i2s' for cpu_dai is that 'samsung-i2s-sec' doesn't have a
capture functionality.

Without this code, cpu_dai will be selected the first one of the
component_list. For example, if I describe nothing to cpu_dai_name,
'samsung-i2s-sec' might be selected to HiFi Primay.

22289ddcd8 ASoC: samsung: i2s: Use specific name for i2s dais
Add specific dais name when components are registered. Component and dai
name will follow their parent dev name, if the name isn't described.  In
case of this driver, each dais will have same name like '11440000.i2s0' by
fmt_single_name function.

The problem having same name is that TM2 machine driver can't detect
capture devices correctly. Machine driver doesn't know which one is proper
to use for cpu dai. The driver just selects to use 'samsung-i2c-sec' that
doesn't have capture functionality because the component of
samsung-i2s-sec is located in the first of the component_list.

I add dai name like 'samsung-i2s', 'samsung-i2s-sec' for each dais. The
reason why adding dai id to 1 is that it doesn't allow to use particular
dai name in case of when I use 0 for dai id.

0a229b15d9 ASoC: arizona: Add handling for audio related device tree entries
Currently all the audio related device tree entries are handled by the
MFD code, for most parts of the Arizona driver we group the device
tree handling with the component that uses it and should do so here as
well.

Add handling in the ASoC code for the audio device tree entries, a
later patch removes the MFD side handling but there is no harm in it
being duplicated temporarily.
