692247196d ASoC: Improve DAPM pop_wait delays
Currently during pop/click debug we're inserting a delay both after
every log message we generate and at explicit points in the sequence,
slowing things down even further than they need to be especially when
many writes get coalesced by the sequence generation code.

Remove the per-printk delay and ensure that we have explicit delays
where we say we want them.

1ca7578043 ASoC: Add delay information for Samsung IISv2 DAIs
Report the current FIFO depth when delay is queried. The FIFO is only
16 frames deep so the latency will be at most a couple of miliseconds
(and we tend to end up reporting zero most of the time) but it may

913d7b4cc0 ASoC: Add support for WM8960 capless mode
The WM8960 headphone outputs can be run in capless mode with OUT3
used to drive a pseudo ground for the headphone drivers. In this
mode the mono mixer is not used, the mixer should be turned on
in concert with the headphone output drivers and the device bias
levels are managed differently.

Also tweak the existing bias management to remove the use of active
discharge while we're at it since that's often audible.

In case if both CPU and CODEC dai has FIFO the delay reported

If none of the dai has FIFO, than the delay will be kept as

As well as disabling the biases of the CODEC the drop into BIAS_OFF will

Since the regulator API does not currently provide notification when

using the regulators. Once 2.6.34 is merged this code can be optimised
to only sync the cache when power was actually removed.
