errata:
When a read command returns less data than specified in the PRDs (for
example, there are two PRDs for this command, but the device returns a
number of bytes which is less than in the first PRD), the second PRD of
this command is not read out of the PRD FIFO, causing the next command
to use this PRD erroneously.
workaround
- forces sg_tablesize = 1
- modified the sg_io function in block/scsi_ioctl.c to use a 64k buffer
allocated with dma_alloc_coherent during the probe in ahci_imx
- In order to fix the scsi/sata hang, when CD_ROM and HDD are
accessed simultaneously after the workaround is applied.
Do not go to sleep in scsi_eh_handler, when there is host failed.

The hang issue is caused by the driver pan display function.
In the mxsfb, the pan display didn't wait the address flip
done before it exits. So this may cause the irq handler
running at the blank state which will cause system hang.
Two things are done in this patch:
1. Remove the 'flip_sem', since the pan_display is always
called under the console lock hold.
2. Add a new completion 'flip_complete" to wait for the
address flip done.

ENGR00274056-1 thermal: add device cooling for thermal driver
cpu cooling is not enough when temperature is
too hot, as some devices may contribute a lot of heat
to SOC, such as GPU, so we need to add device cooling
as well, when system is too hot, devices can also take
their actions to lower SOC temperature.
when temperature cross the passive trip, device cooling
driver will send out notification, those devices who
register this devfreq_cooling notification will take
actions to lower SOC temperature.

ENGR00307635-5 ASoC: imx-wm8962: Add non-SSI cpu dai support
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.

ENGR00312217-1 ASoC: fsl: pop noise with wm8962
The reason of pop noise is that we change the sysclk in hw_free, which is

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().

ENGR00277471 ASoC: fsl: Fix set-mute-failed issue after WM8962 capture
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.

ENGR00274386-2 ASoC: imx-wm8962: Set MCLK source clock to 0Hz in hw_free()
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 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.

evbug will open the mma8450 on i.MX6SL_EVK and mma8450 will work in 2G mode by default.
That is the reason why mma8450 logs will be printed out. The main changes is below:
* Remove the open(), close() hook out of the drivers. The open() and close()
hook in input framwork is defined as void type. It isn't strictly safe in
logic when some error happends. So remove them out.
* Modify the mma8450 to standby mode by default. It will be more power saving
and there would be no log printing out after booting up.
* Provide the sys interface to modify the mma8450 work modes. Then the higher
layer can modify the the mma8450 work mode via the interface. It would be
much safer.There would be a sclaemode interface in the folder of
/sys/devices/soc0/soc.1/2100000.aips-bus/21a0000.i2c/i2c-0/0-001c/scalemode
User can use cat to read the current scalemode and echo to write. The mode
is defined as: MODE_STANDBY: 0 MODE_2G:1 MODE_4G:2 MODE_8G:3
* Add mutex to protect and some error handling.
