The volume and bytes kcontrols are currently not freeing their
memory on initialization failures. When an error occurs, all the
widgets loaded so far are unloaded via sof_widget_unload().
But this only happens for the widgets that got successfully loaded.
Fix that by kfree()-ing the allocated memory on load error.

This adds a new mode WM8904_CLK_AUTO which automatically enables the FLL
if a frequency different than the MCLK is set.
These additions make the codec work with the simple-card driver in
general and especially in systems where the MCLK doesn't match the
required clock.

On KBL platform, the microphone is attached to external codec(rt5514)

Due to limitations of the clocking configuration, we have no way of
scheduling our hibernation before the bdw dsp hibernates. This causes
issues when the system suspends with an open stream. We need userspace
to toggle the kcontrol before we are suspended so that any writes on
suspend are not lost and we don't corrupt the regmap.

The irq is disabled at suspend to avoid running the threaded irq
handler after the codec has been powered off. At resume, codec irq is
re-enabled and the interrupt status register is checked to see if
headphone has been pluggnd/unplugged while the device is suspended.
There is still a chance that the headphone gets enabled or disabled
after the codec is suspended. disable_irq syncs the threaded irq
handler, but soc-jack's threaded irq handler schedules a delayed
work to poll gpios (for debounce). This is still OK. The codec won't
be powered back on again because all audio paths have been suspended,
and there are no force enabled supply widgets (MICBIAS1 is disabled).
The gpio status read after codec power off could be wrong, so the
gpio values are checked again after resume.

MCLK1 gets disabled at suspend and re-enabled at resume. Before
MCLK1 is re-enabled, if the DSP is already on (either the DSP was
left on during suspend, or the DSP is turned on early at resume),
i2c register read returns garbage and corrupts the regmap cache.
This patch stops the DSP before suspend and restarts it after
resume with a dalay to ensure MCLK is on while loading firmware.

The codec dies when RT5677_PWR_ANLG2(MX-64h) is set to 0xACE1
while it's streaming audio over SPI. The DSP firmware turns
on PLL2 (MX-64 bit 8) when SPI streaming starts. However regmap
does not believe that register can change by itself. When
BST1 (bit 15) is turned on with regmap_update_bits(), it doesn't
read the register first before write, so PLL2 power bit is
cleared by accident.
Marking MX-64h as volatile in regmap solved the issue.

Before a hotword is detected, GPIO1 pin is configured as IRQ
output so that jack detect works. When a hotword is detected,
the DSP firmware configures the GPIO1 pin as GPIO1 and
drives a 1. rt5677_irq() is called after a rising edge on
the GPIO1 pin, due to either jack detect event or hotword
event, or both. All possible events are checked and handled
in rt5677_irq() where GPIO1 pin is configured back to IRQ
output if a hotword is detected.

The firmware rt5677_elf_vad is an ELF binary obtained from
request_firmware(). Sections of the ELF are loaded to
the DSP via SPI. A model (e.g. en_us.mmap) can optionally be
loaded to the DSP at RT5677_MODEL_ADDR to overwrite the
baked-in model in rt5677_elf_vad.
Then we switch to DSP mode, load firmware, and let DSP run.
When a hotword is detected, an interrupt is fired and
rt5677_irq() is called. When 'DSP VAD Switch' is turned off,
the codec is set back to normal mode.
The kcontrol 'DSP VAD Switch' is automatically enabled/disabled
when the hotwording PCM stream is opened/closed.

soc-core has some API which is used from topology, but it is doing
topology specific operation at soc-core.
soc-core should care about core things, and topology should care
about topology things, otherwise, it is very confusable.
For example topology type is not related to soc-core,
it is topology side issue.
This patch removes meaningless check from soc-core.
This patch keeps extra initialization/destruction at
snd_soc_add_dai_link() / snd_soc_remove_dai_link()
which were for topology.

It is easy to read code if it is cleanly using paired function/naming,
like start <-> stop, register <-> unregister, etc, etc.
But, current ALSA SoC code is very random, unbalance, not paired, etc.
It is easy to create bug at the such code, and is difficult to debug.
Now ALSA SoC has snd_soc_add_component(), but there is no paired
snd_soc_del_component(). Thus, snd_soc_unregister_component() is
calling cleanup function randomly. it is difficult to read.
This patch adds missing snd_soc_del_component_unlocked() and
balance up code.

snd_soc_lookup_component() is using mix of continue and break
in the same loop. It is odd.

It is easy to create bug at the such code, and it will be difficult to

ALSA SoC has soc_bind_dai_link(), but its paired soc_unbind_dai_link()
is not implemented.
More confusable is that soc_remove_pcm_runtimes() which should be
soc_unbind_dai_link() is implemented without synchronised
to soc_bind_dai_link().
This patch cleanup this unbalance.

If we focus to soc_bind_dai_link() at snd_soc_instantiate_card(),
we will notice very complex operation.
static int snd_soc_instantiate_card(...)
{

for_each_card_links(card, dai_link) {

}
...
}
As you see above, it is doing very complex method.
The problem is binding dai_link via "card pre-linked" (= (1)) and
"topology added dai_link" (= (3)) are separated.
The code can be simple if we can bind dai_link when dai_link
is connected to *card list*.
This patch do it.

soc_init_dai_link() is needed to be called before soc_bind_dai_link().
int snd_soc_instantiate_card()
{
for_each_card_prelinks(...) {
(1) ret = soc_init_dai_link(...);
...
}
...
for_each_card_prelinks(...) {
(2) ret = soc_bind_dai_link(...);
...
}
...
for_each_card_links(...) {
...
(A) ret = soc_init_dai_link(...);
...
(B) ret = soc_bind_dai_link(...);
}
...
(1) is for (2), and (A) is for (B)
(1) and (2) are for card prelink dai_link.
(A) and (B) are for topology added dai_link.
soc_init_dai_link() is sanity check for dai_link, not initializing today.
Therefore, it is confusable naming. We can rename it as sanity_check.
And this check is for soc_bind_dai_link().
It can be more simple code if we can call it from soc_bind_dai_link().
This patch renames it to soc_dai_link_sanity_check(), and
call it from soc_bind_dai_link().

Set trigger order for FE DAI links to SND_SOC_DPCM_TRIGGER_POST
to trigger the BE DAI's before the FE DAI's. This prevents the
xruns seen on playback pipelines using the link DMA.

Currently, the trigger orders SND_SOC_DPCM_TRIGGER_PRE/POST
determine the order in which FE DAI and BE DAI are triggered.
In the case of SND_SOC_DPCM_TRIGGER_PRE, the FE DAI is
triggered before the BE DAI and in the case of
SND_SOC_DPCM_TRIGGER_POST, the BE DAI is triggered before
the FE DAI. And this order remains the same irrespective of the
trigger command.
In the case of the SOF driver, during playback, the FW
expects the BE DAI to be triggered before the FE DAI during
the START trigger. The BE DAI trigger handles the starting of
Link DMA and so it must be started before the FE DAI is started
to prevent xruns during pause/release. This can be addressed
by setting the trigger order for the FE dai link to
SND_SOC_DPCM_TRIGGER_POST. But during the STOP trigger,
the FW expects the FE DAI to be triggered before the BE DAI.
Retaining the same order during the START and STOP commands,
results in FW error as the DAI component in the FW is still
active.
The issue can be fixed by mirroring the trigger order of
FE and BE DAI's during the START and STOP trigger. So, with the
trigger order set to SND_SOC_DPCM_TRIGGER_PRE, the FE DAI will be
trigger first during SNDRV_PCM_TRIGGER_START/STOP/RESUME
and the BE DAI will be triggered first during the
STOP/SUSPEND/PAUSE commands. Conversely, with the trigger order
set to SND_SOC_DPCM_TRIGGER_POST, the BE DAI will be triggered
first during the SNDRV_PCM_TRIGGER_START/STOP/RESUME commands
and the FE DAI will be triggered first during the
SNDRV_PCM_TRIGGER_STOP/SUSPEND/PAUSE commands.
