The sw2iso count should cover ARM LDO ramp-up time,
the MAX ARM LDO ramp-up time may be up to more than
100us, this patch sets sw2iso to 0xf (~384us) which
is the default value.

Commit 65e6b5f1b4a7 ("ASoC: wm8960: Fix playback in CPU DAI master
mode") broke wm8960 codec master mode by choosing "bad" SYSCLK values.
This patch partially reverts commit mentioned above by restoring the
SYSCLK values. It turns out that using params_physical_width instead of
params_width in the previous patch it is enough to fix CPU DAI mode.

With the current rates for MCLK is not possible to derive bitclk
for all files in S20_3LE format and also for files with S24_LE sampled
at 48000Hz.
In order to fix this, we need to find a better MCLK value. We did this
in two steps:
1) Use params_physical_width to get rid of S20_3LE burden.
2) Brute force into all available rates which can pass fsl_sai_set_bclk
algorithm.
Thus we found 36864000 to be the smallest acceptable rate for MCLK.

For the slot support SD3.0 card, during system suspend, if plug out
the sd card, and insert another SD3.0 card, after system resume back,
SD3.0 card can't be recognised as SD3.0 card, just SD2.0 card.
This is bause the time delay between vmmc regulator off and on is
too small, this patch add the oo-on-delay in vmmc-supply regulator,
to assign proper delay value.

Commit 2c2a56059ff7e7e4 ("MLK-11407-8: ARM: dts: i.mx6sx/i.mx6ul: add
ldo-bypass support") was backported from imx_4.1.y and added a
duplicate i2c node which was already present upstream.
This patch removes the duplicated node and moves the difference
(clocks for wm8960) to the existing upstream node.

Upstream commit bf3251e ("ARM: dts: imx6ul-14x14-evk: Add audio
support") switched to using the simple sound card driver.
This does not seem to work anymore on vanilla 4.9.5 (aplay gets stuck
with no sound output). Adding the rest of our out internal patches
from 4.1 causes even greater issues, the card does not even enumerate.
While we eventually want to switch to using simple sound card, lets
revert to using the fsl,imx-audio-wm8960 driver for the time being,
while investigating what it takes to switch to the simple sound card
driver.

CMA region is a must to avoid the multile memory mapping
for the DMAed memory and also benifit the large continious
phisical memory allocation.
The default value is depend on the target system design and
user cases definition. This is not suitable to put this into
the soc.dtsi, thus we put it into the board DTS.
customer can override the value by changing cma size in DTS file.
Again, customer need set the CMA size correctly according to the
target system. The incorrectly CMA size can cause Linux kernel fail
to boot up.CMA disabled or CMA size set to zero is also not allowed.
