The reason of pop noise is that we change the sysclk in hw_free, which is
for another wm8962 issue. So in currently the pop noise can't be resolved
with no confliction. So for Android, because the samplerate is fixed. we can
use other workaround for this issue: change the sysclk in the set_bias().

The current imx-wm8962 machine driver is designed for SSI as CPU DAI only
while as its name we should make the driver more generic to any other CPU
DAI on i.MX serires -- ESAI, SAI for example.
So this patch makes the driver more general so as to support those non-SSI
cases.

Pulseaudio will detect the Headphone Jack, then swith to Headphone.
So register new Jack for Headphone, the iface=CARD.

slow issue"
The root cause of playback slow issue should be trying to get DSPCLK_DIV
before enabling SYSCLK of WM8962. Since we have a patch fixed it, we can
revert this work round.
This reverts commit 49a3ca545a88cdf4aa597c4dd7d904b4faaea555.

As DAPM would do the sync() for us, we don't need to handle it by ourselves.
And leaving snd_soc_dapm_sync() here is dangerous because it would disable
the clock from WM8962 during the short period of the output route changing
since we don't leave the alternative route's enanbling to this machine driver
but to DAPM core.

Alsa machine drivers need snd_soc_pm_ops to support normal suspend/resume
feature, thus add this to all machine drivers.
Also add missing SUSPEND and RESUME cases to trigger() in fsl_ssi.c

The resume function is useless for the driver because registered jack pin has
already handled suspend/resume cases, thus drop it.

There're two GPIOs connected to the headphone jack and microphone jack,
thus add the states detection.

We only need to mute WM8962 after playback, so add direction check
before doing mute.
And a mute failure would cause hw_free() abruptly return after it,
which might drop the essential procedure code for FLL controlling.
Thus put mute before FLL controlling code and drop its return check.

When DAPM closed WM8962 after playback, its driver would prompt
'wm8962 0-001a: Unsupported sysclk ratio 500' due to the invalid
divisor calculated by WM8962 codec driver.
To fix it, we can work around by setting its MCLK source to 0Hz,
so the codec driver would never get an invalid divisor any more.
Since hw_params() would re-set the MCLK source, no need to worry
about any side-effect.

We are using auto sample rate feature of WM8962, whereas it doesn't
support those sample rates bigger than 96KHz, 192Khz for example,
so 384 * samplerate would be too big for it to handle. When playing
192KHz 24bit wav file, the playback would be slower than normal.

WM8962 needs its MCLK when powerup -- wm8962_resume(). Thus it's better
to control the MCLK in codec driver. Thus remove the clock enable in
machine dirver accordingly.

We followed community way by using set_bias() to set FLL of WM8962.
But this can't meet our requirement: aplay -Dhw: 16khz.wav 24khz.wav.
Thus use hw_params() and hw_free() instead.

If the 'failed to find codec platform device' error path is executed, it should
jump to 'fail' label instead of returning an error immediately.
'fail' label will then free the ssi_np and codec_np previously acquired nodes.

Commit 8de2ae2a7f1fd71dc56d6b014029f93093e9c5d5 upstream.
This is the initial imx-wm8962 device-tree-only machine driver working with
fsl_ssi driver. More features can be added on top of it later.
