When unplug, blank happens, HDMI audio can't play properly. So in
driver, audio pcm would be disconnected when event above happens.
However, pulse audio can't process disconnect event properly and if an
blank or unplug event happens, HDMI sink would lost and can't be back
again.
In this patch, instead of disconnecting audio PCM stream, triggering
stop audio pcm while unplug and blank, triggering start again while plug
and unblank if the audio pcm is triggerd stop in the unplug/blank event.

The current code will gets the clock frequency which is used by
gpmi_nfc_compute_hardware_timing(). It makes the code a little mess.
So move the `get clock frequency` code to the
gpmi_nfc_compute_hardware_timing() itself. This makes the code tidy
and clean.

The gpmi_nfc_compute_hardware_timing{} should contains all the
fields setting for gpmi timing registers. It already contains the fields
for HW_GPMI_TIMING0 and HW_GPMI_CTRL1.
So it is better to add a new field setting for HW_GPMI_TIMING1 in
this data structure. This makes the code more clear in logic.
This patch also changs some comments to make the code more readable.

HDMI audio driver is responsible for add IEC header into audio sample.
In HDMI audio driver, a variable named rtd->appl_bytes is maintained to
stand for how many audio sample have already processed. appl_bytes
stands for how many audio sample the user space have already feed into
kernel driver. So we use the connt = appl_bytes - rtd->appl_bytes to
decide how many data need to be processed. And the processed data would
be write into an preallocated buffer called hw_buf in driver.
When doing seek operation, the appl_bytes changes in an wide range. So
it is possible that the count value is far larger than the size of
hw_buf and the memory access un-existed address error would happens.
In this patch, Add check operation for count to avoid kernel panic.

After doing some suspend/resuem test, secondary cores BogoMIPs
will be wrong, the root cause is that when cpufreq is changed,
we only update the online cpus' loops_per_jiffy, and when secondary
cores back to online, we skip the loops_per_jiffy calibration. During
suspend/resume, the cpufreq can be changed during disabling/enabling
secondary cores, which will make secondary cores loops_per_jiffy
wrong, so here we need to update all possible cpus' loops_per_jiffy
when cpufreq is changed.

i2c device (isl29023) can not suspend once during hdmi
audio suspend/resume test, and print log:

2-0044 failed to suspend: error -4 PM: Some devices failed to
suspend PM: resume of devices complete after 40.936 msecs
Restarting tasks ... done.
Because suspend function in isl29023 driver requires i2c bus
to write isl29023 device. I2C apdater driver process any signal
as exception during waiting the bus idle, so once user space sent
out signal during suspend, I2C device cannot request bus.
Using "fatal_signal_pending()" instead of "signal_pending()"
to avoid the waiting of bus idle to be terminated by general
signals except SIGKILL. After the change, i2c adapter can be
terminated by kill signal from user space with "CTRL+C" or
kill command operation.

Ethernet performance is downgraded when wait mode on in
100Mbps mode.
wait mode off:
100Mbps mode: tx bandwidth is 94Mbps
rx bandwidth is 94Mbps
wait mode on:
100Mbps mode: tx bandwidth is 30Mbps
rx bandwidth is 94Mbps
After apply the patch:
wait mode on:
100Mbps mode: tx bandwidth is 94Mbps
rx bandwidth is 94Mbps
Wait mode on cause enet interrupt has long latency, which
results in BD entries are full and stop tx queue, so cpus
have more chance to enter wait mode.
Incresing TX BD entries can properly accommodate the blance
between BD request before tx packets and BD release after tx
completion in interrupt process.

1) In the interrupt handler, we access sync interrupt
control registers 2 times, and each time with spin
lock being held and then released, which may cause
potential racing on the registers. We see that
as long as the racing happens with two displays
enabled on the same IPU, one IPU display channel
will lose EOF interrupt and it makes its fb's pan
display ioctrl fail with timeout. This patch changes
to hold the spin lock one time for the whole irq
handler, as the handler should return quickly.
Holding and releasing the spin lock unnecessarily
may bring performance penalty as well.
2) We do not need to use spin_lock_irqsave() and
spin_unlock_irqrestore() in the interrupt handler,
as we are already in the hard irq context. Using
spin_lock() and spin_unlock() is enough to protect
the registers.
3) Clear an interrupt control bit as soon as its related
handler finishes.

Ensure that the pull-up is enabled when the DQS line of LPDDR2
is floated when DDR freq is dropped to 24MHz. This is required
else its possible that the DDR will latch incorrect data when it

CKE line should not be floated as it may cause DDR to incorrectly
exit self-refresh mode.
Also add 25 nops after the code that removes DDR from self-refresh.
We need this to ensure that the prefetcher block in A9 does not
access any instruction from DDR before the DDR exits self-refresh.
The A9 prefetch depth is about 23, hence 25 nops.

Make sure the Pull Ups are enabled on the DQS lines of
LPDDR2 memory. Without that its possible that the data
latched by the memory will be incorrect when exiting from
self-refresh mode. So only set the drive strengths to 0
when floating the DDR IO pads before entering suspend.
Also never float the CKE pad, this pin always needs to be
driven, else the DDR may incorrectly exit self-refresh.
Hence remove the line that was setting CKE drive strength
to zero (GRP_CTLDS).

HMAC keys often need to be reduced to under the size of a digest to
be used. The driver does this psuedo-synchronously through the use of
hash_digest_key(), which builds a sequence pointered job descriptor to
perform this function.
When this function built the job descriptor, it correctly accounted for the
number of instructions and number of pointers that would go into its
construction. However, it failed to account for the fact that both the
sequence in and out pointers used extended lengths, adding 8 more bytes to
the required job descriptor. This caused the descriptor to overrun the
allocated buffer by that amount, resulting in memory corruptions.

Multiple function in asynchronous hashing use a saved-state block,
a.k.a. struct caam_hash_state, which holds a stash of information
between requests (init/update/final). Certain values in this state
block are loaded for processing using an inline-if, and when this
is done, the potential for uninitialized data can pose conflicts.
Therefore, this patch improves initialization of state data to
prevent false assignments using uninitialized data in the state block.
This patch addresses the following traceback, originating in
ahash_final_ctx(), although a problem like this could certainly
exhibit other symptoms:

When system enter suspend, we increase CPUFreq to the highest point
without update the global loops_per_jiffy, it will lead to udelay
inaccurate during the last phase of suspend/resume.
WB counter and RBC counter need at least two 32K cycles to finish,
here we add 80us for safe.

For i.MX6DLTO1.1 and i.MX6DQTO1.2, the disconnection-bit can only be set after
the resume finished, otherwise, the remote-wake-up may fail. Because if the
device not switch to High-Speed 45ohm termination resistors mode, when the
disconnection detection bit is set the disconnection detection circuit will
detect a high speed disconnection by mistake.
