Today, hp_jack_event and mic_jack_event always return 0. However,
snd_soc_dapm_disable_pin and snd_soc_dapm_enable_pin may return a
non-zero value, this will cause the user who calling hp_jack_event

the SPDIF transmit Professional C channel registers,
192bit SPDIF receive C channel registers, and 192bit SPDIF
transmit C channel registers.
There are two output lines, SPDIF_OUT1 and SPDIF_OUT2, the
original REG_SPDIF_STCSCH and REG_SPDIF_STCSCL are used for
SPDIF_OUT1, the new REG_SPDIF_STCSPH and REG_SPDIF_STCSPL

The fsl_sai driver calculates the number of pins used and enables
multiple channels if necessary. This means the SAI expects data in
one FIFO per pin. The SDMA engine only services a single FIFO, so
multi pin support doesn't work at all.
This patch enables the software combine mode in chips that support
it. With this the SAI presents only a single FIFO to the outside
and distributes the data into the different FIFOs internally.

Implement SPDIF bypass mode. It implies internal SoC
routing of SPDIF input signal to SPDIF output signal. The
test bed requires two boards: B1 configured in bypass mode,
and B2 to feed B1 SPDIF RX port and read B1 SPDIF TX port:
B2 TX -> B1 RX,
B2 RX <- B1 TX.
The test procedure:
a) Boot both boards
b) B2: start "arecord <spdifcard> -r 48kHz | aplay <local DAC>"
c) B2: start "aplay <spdifcard> -r 48kHz <2ch 48kHz audio file>"
d) B1: enable bypass mode:
amixer -cimxspdif cset numid=8,iface=PCM,name='Bypass Mode' on
e) B2: check DAC audio, make sure the same sample rate is used at
steps b) and c), in example above the rate is 48kHz.
f) B1: try to run "aplay" or "arecord" on imxspdif card while in
bypass mode - both must fail until bypass mode is disabled
g) B1: disable bypass mode:
amixer -cimxspdif cset numid=8,iface=PCM,name='Bypass Mode' off
h) B1: check the usual playback and capture on imxspdif card.
During this test try to set bypass mode - must not be allowed
while playback or capture is running.

With pause and resume test for ARC, there is occasionally
channel swap issue. The reason is that currently driver set
the DPATH out of reset first, then start the DMA, the first
data got from FIFO may not be the Left channel.
Moving DPATH out of reset operation after the dma enablement
to fix this issue.

There is no defer probe when adding platform component to
snd_soc_pcm_runtime(rtd), the code is in snd_soc_add_pcm_runtime()
snd_soc_register_card()
-> snd_soc_bind_card()
-> snd_soc_add_pcm_runtime()
-> adding cpu dai
-> adding codec dai
-> adding platform component.
So if the platform component is not ready at that time, then the
sound card still registered successfully, but platform component
is empty, the sound card can't be used.
As there is defer probe checking for cpu dai component, then register
platform component before cpu dai to avoid such issue.

When system enter suspend, the machine driver suspend callback
function will be called, then the cpu driver trigger callback
(SNDRV_PCM_TRIGGER_SUSPEND) be called, it would disable the
interrupt.
But the machine driver suspend and cpu dai driver suspend order
maybe changed, the cpu dai driver's suspend callback is called before
machine driver's suppend callback, then the interrupt is not cleared
successfully in trigger callback.
So need to clear interrupts in cpu dai driver's suspend callback
to avoid such issue.

Hi Mark
These are v3 of parsing for daifmt.
I want to add new audio-graph-card2 sound card driver,
and this is last part of necessary soc-core cleanup for it.
Current some drivers are using DT, and then,
snd_soc_of_parse_daifmt() parses daifmt, but bitclock/frame provider
parsing part is one of headache, because we are assuming below both cases.
A) node {
bitclock-master;
frame-master;
...
};
B) link {
bitclock-master = <&xxx>;
frame-master = <&xxx>;
...
};
The original was style A), and style B) was added later.
snd_soc_of_parse_daifmt() parses A) style as original style,
and user need to update to B) style for clock_provider part if needed.
To handle it more flexibile, this patch-set adds new functions
which separates snd_soc_of_parse_daifmt() helper function.
snd_soc_daifmt_parse_format() : format part
snd_soc_daifmt_parse_clock_provider_as_flag() : clock part for style A)
snd_soc_daifmt_parse_clock_provider_as_phandl() : clock part for style B)
snd_soc_daifmt_parse_clock_provider_as_bitmap() : clock part use with _from_bitmap
v1 -> v2
- tidyup parse_clock_provider functions to _as_flag/phandle/bitmap()
- don't exchange code style on each drivers.
v2 -> v3
- use daifmt as much as possible (don't use daiclk) on each driver.

When using the driver in I2S TDM mode, the fsl_esai_startup()
function rewrites the number of slots previously set by the
fsl_esai_set_dai_tdm_slot() function to 2.
To fix this, let's use the saved slot count value or, if TDM
is not used and the number of slots is not set, the driver will use
the default value (2), which is set by fsl_esai_probe().

On Asymmetric multiprocessor, there is Cortex-A core and Cortex-M core,
Linux is running on A core, RTOS is running on M core.
The audio hardware device can be controlled by Cortex-M device,
So audio playback/capture can be handled by M core.
Rpmsg is the interface for sending and receiving msg to and from M
core, that we can create a virtual sound on Cortex-A core side.
A core will tell the Cortex-M core sound format/rate/channel,
where is the data buffer, what is the period size, when to start,
when to stop and when suspend or resume happen, each of this behavior
there is defined rpmsg command.
Especially we designed the low power audio case, that is to
allocate a large buffer and fill the data, then Cortex-A core can go
to sleep mode, Cortex-M core continue to play the sound, when the
buffer is consumed, Cortex-M core will trigger the Cortex-A core to
wakeup to fill data.
changes in v5:
- remove unneeded property in binding doc and driver
- update binding doc according to Rob's comments.
- Fix link issue reported by kernel test robot
changes in v4:
- remove the sound card node, merge the property to cpu dai node
according to Rob's comments.
- sound card device will be registered by cpu dai driver.
- Fix do_div issue reported by kernel test robot

The only usage of these is to assign their address to the 'ops' field in
the snd_soc_dai_driver struct, which is a pointer to const. Make them
const to allow the compiler to put them in read-only memory.

The only way this driver can be probed is via devicetree, which always
provides driver data.
Remove the unneeded of_device_get_match_data() error check, as it
can never fail.
