With SCU standby enabled, SCU CLK will be turned off when all processors
are in WFI mode. And the clock will be turned on when any processor
leaves WFI mode.
This behavior should be preferable in terms of power efficiency of
system idle. So let's set the SCU standby bit to enable the support in
function scu_enable().
Cortex-A9 earlier than r2p0 has no standby bit in SCU, so we need to
skip setting the bit for those.

ARM: 8103/1: save/restore Cortex-A9 CP15 registers on suspend/resume
The CP15 diagnostic register holds ARM errata bits on Cortex-A9, so it
needs to be saved/restored on suspend/resume. Otherwise, the
effectiveness of errata workaround gets lost together with diagnostic
register bit across suspend/resume cycle. And the CP15 power control
register of Cortex-A9 shares the same problem.
The patch adds a couple of Cortex-A9 specific suspend/resume functions
to save/restore these two Cortex-A9 CP15 registers across the
suspend/resume cycle.

i2c: imx: fix the i2c bus hang issue when do repeat restart
Test i2c device Maxim max44009, datasheet is located at:
http://www.maximintegrated.com/datasheet/index.mvp/id/7175
The max44009 support repeat operation like:
read -> repeat restart -> read/write
The current i2c imx host controller driver don't support this
operation that causes i2c bus hang due to "MTX" is cleared in
.i2c_imx_read(). If "read" is the last message there have no problem,
so the current driver supports all SMbus operation like:
write -> repeat restart -> read/write
IMX i2c controller for master receiver has some limitation:
- If it is the last byte for one operation, it must generate STOP
signal before read I2DR to prevent controller from generating another
clock cycle.
- If it is the last byte in the read, and then do repeat restart, it must
set "MTX" before read I2DR to prevent controller from generating another
extra clock cycle.
The patch is to fix the issue.

The filter() function is currently called by xlate() while it transfers
imx_dma_data as a local variable to the filter() but releases the data

So this patch just stores the imx_dma_data into sdmac to make usre the

fsl_asoc_xlate_tdm_slot_mask() is different with snd_soc_xlate_tdm_slot_mask().

the slot is disabled. If using fsl_asoc_xlate_tdm_slot_mask(), the esai will
work abnormally. So revert this patch, make the esai use default function.

I received a report this morning from one of the Novena developers that
the behaviour of the iMX6 ASoC codec driver (using imx-pcm-dma.c) was
sub-optimal under high system load.
While there are issues relating to system load remaining, upon reviewing
the ASoC imx-pcm-dma.c driver, it was noticed that it not using the
residue support, because SDMA doesn't support it. This has the effect
that SDMA has to make multiple calls into the ASoC and ALSA code, one
for each period.
Since ALSA's snd_pcm_elapsed() does not need to be called multiple times
and it is entirely sufficient to call it once to update ALSA with the
current buffer position via the pointer method, we can do better here.
We can also avoid stopping the DMA entirely, just like real cyclic DMA
implementations behave. While this means that we replay some old samples,
this is a nicer behaviour than having audio stop and restart.
The changes to achieve this are relatively minor - imx-sdma.c can track
where the DMA is to the nearest descriptor boundary - it does this
already when deciding how many callbacks to issue. In doing this,
buf_tail always points at the descriptor which will complete next.
The residue is defined by the bytes remaining to the end of the buffer,
when the buffer is viewed as a single block of memory [start...end].
So, when we start out, there's a full buffer worth of residue, and this
counts down as we approach the end of the buffer, eventually becoming
zero at the end, before returning to the full buffer worth when we
wrap back to the start.
Moving the walking of the descriptors into the interrupt handler means
that we can update the BD_DONE flag at interrupt time, thus avoiding
a delayed tasklet stopping the cyclic DMA.
This means that the residue can be calculated from (total descriptors -
buf_tail) * descriptor size. This is what the change below does. We
update imx-pcm-dma.c to remove the NO_RESIDUE flag since we now provide
the residue.

ASoC: fsl-ssi: Fix baudclock handling
The baudclock may be used and set by different streams.
Allow only the first stream to set the bitclock rate. Other streams have
to try to get to the correct rate without modifying the bitclock rate
using the SSI internal clock modifiers.
The variable baudclk_streams is introduced to keep track of the active
streams that are using the baudclock. This way we know if the baudclock
may be set and whether we may enable/disable the clock.
baudclock enable/disable is moved to hw_params()/hw_free(). This way we can
keep track of the baudclock in those two functions and avoid a running
clock while it is not used. As hw_params()/hw_free() may be called
multiple times for the same stream, we have to use baudclk_streams
variable to know whether we may enable/disable the clock.
