ENGR00132153 sgtl5000: do not enforce symmetry if rate is unknown
ENGR00132525 sgtl5000: audio clock gating
ENGR00132580 allow prediv by 1 for ext1 clk

to remove the device from the audio subsystem, when it fails to reigster

The CS42888 can only playback or record the multiple 44k streams,

1)There is still pop noise sometimes when start/stop/pausing a playback,
this patch is used to further reduce the pop noise.
2)Enter low power mode(power down DAC) when there is no playback for 5 seconds.
3)Modify amixer controls "Speaker Playback Switch" and "Headhpone Playback

Changes such that DAC Mux will only affect whether the headphone
output gets connected to the DAC or Line in.
The previous implementation of the DAC Mux allowed the dapm power
level of the sgtl5000 to be affected whether audio was playing or
not. It also controlled the an internal osc which had no effect
since it didn't affect whether mclk was turned on.

Due to an apparent hw bug we have to shift data in the audio buffer by
one byte to play out S/PDIF. ENGR00122025 and ENGR00122231 are a
workaround for playback with non-mmapped buffers. This patch is
the workaround for mmapped buffers.

Trying to free already-free IRQ 240 causes the warning dumped out

The ak4647_codec is not initialized as there is no ak4647 codec existing
on MX35 board. In the 31 kernel, the card and codec drivers are
registered separately, and there is no check whether the codec is probed
successfully or not. On MX35 board, the card is sucessfully registered,
but there is no ak4647 codec. In this case, the system will crash if the
system try to invoke the codec's resume function.
To resolve the problem, add a check in registering the card. If the
codec does not exist, give up registering the card either.

wm8580 is using regulators that can't change state. The
regulator driver doesn't handle this case well so it crashes
during regulator_bulk_enable. Eventually this will be fixed in the
regulator driver. For now, remove regulators from list in
wm8580 driver.
Fix spi_rw err. hw_write needs to return transferred data length.

Move regulator control into codec drivers.
Move codec platform data to machine layer.
Remove unused fields from mxc_audio_platform_data.
soc multiple audio cards support:
dai_list is a list for all registered codec/cpu dais.
One codec/cpu dais can't be registered twice, so move the
cpu dai registering into imx-ssi.c/imx-esai.c
Fix ak4647_read_reg error.
Put ssi/esai mode in the cpu_dai private_data.
sgtl5000: Fix the power for MX35
1. MX35 vddio and vddd are directly connected to
external 3V3. It has no regulator control.
2. sgtl5000 needs some time to be ready after vdda
is switched on so msleep(1) is added before regiter
read/write.
3. On MX35 platform, vdda is from VCAM.
