90752ebfb4 v4l2: Add mutex to streamon() and dqbuf()in v4l2 framework. 
When v4l2 streamon() is called the framework moves to streamon state,
after queueing the buffer. A state check is performed during dqbuf().
Sometimes when dqbuf() is called streamon() function has not completed
setting the state transisiton flag. This results in failure to dqbuf() as
the framework has not moved to streamon. This patch adds a mutex
around state transitions and dqbuf() calls.

it performs a read. This fix creates a dummy read event that
happens every time that the VCAP is powered on that will ignore
the false positive VBIF interrupt error, so that during normal

d2e5aa23fd msm: camera: Add support for instance handle based buffer lookup. 
Currently when VFE requests for a free buffer, we search based
on the image mode sent from VFE. In some cases, there can be
multiple instances with the same image mode. This means the
buffer lookup logic has to take into consideration other
parameters like current usecase, vfe operation mode etc.
To ease this, add support for buffer lookup based on
the instance handle. The instance handle contains information
about where to get the buffer from. So the buffer lookup
logic does not have to know about other details. The instance
handle is decided when the user sets the format for a particular
instance. It is passed on to the VFE during AXI configuration.
VFE stores this and sends it whenever it requests for a free
buffer for a particular output.
Keep the current image_mode based buffer lookup logic for
legacy targets.

212ebe6539 msm: mpq8064: VCAP corner case bug fixes 
Closing VCAP devices could be called without calling stream off:
This problem would make VCAP resources taken by devices no longer
running.

Using unsigned variable to store signed result: This problem would
allow stream on to continue even when function returned error.

Fix problem of reading VP irq status register too early: It was
possible for cadence detection bit to be propgated faster by only
a few clock cycles then the picture done bit. When the irq status
read was performed and by the time a write to the clear register
was performed the picture done bit would propgate. Since the irq
is rising edge triggered this would cause a problem and the irq
would not be triggered until VP was reset.

Remove unused code

3e11253611 msm: mpq8064: Separate q/dq buffer for VCAP de-interlacing mode 
This change fixes a crash when running VCAP in de-interlace mode.
The problem was noticed in the introduction of kernel 3.4. VCAP
was improperly using the videobuf2 framework APIs. Since VCAP is
already reliant on queue structure provided by videobuf2 framework,
we created our own basic version of the qbuf and dqbuf calls that
have some similarities to the videobuf2 framework. This addition
was necessary since we are calling qbuf from a kernel work thread.
Since moving to kernel 3.4 there has been a change in videobuf2
qbuf that dereferences the current process.s mm_struct, from a
kernel work thread this struct is NULL, which was causing a crash.
When we are de-interlacing a captured video we are cycling the
buffers internally in the driver, which is why we needed to create
our own q/dq buffer functionality.

core's v4l2 subdevice.
If the usecase demands that the interrupts from two
different hw cores be composited into a single interrupt,
(for eg: VFE and ISPIF), then the cam server stores this
configuration in its interrupt lookup table. When the
interrupt is triggered on the composited interrupt,
it is dispatched to the individual hardware cores
which have been composited into that interrupt.

    Revert "radio-iris: Configure search direction as passed by FM APP"

    As per V4L2 framework APP should pass the parameter as '1' to
    search in forward direction and '0' to search in downward
    direction. Reverting the change that was uploaded as it configured
    the search direction directly that it received it from the APP.
    APP should pass '1' for SEEK UP and '0' for SEEK DOWN . The driver
    should check for the direction before configuring. To the FM SOC,
    '0' means SEEK-UP and '1' means SEEK-DOWN. If APP passes '1' driver
    understands that user is requesting SEEK-UP operation and will
    configure the direction as '0'.

    This reverts commit 4667d9d437c2fe5501db1fd741b4643452eda61b

    radio: iris: Fix the FM FTM Tx configuration failure

    FM configuration failure is due to two issues. Since the calibration
    will take around 6 seconds to complete, any commands sent to SOC
    during that time will fail.Added a state machine to prevent the
    execution of another command while FM calibration is in progress.

    The other issues is with the Get tuner command.FM kernel driver is
    sending the Rx specific command to get the Tx configuration.
    Send the proper command to get the TX configuration parameters.

    radio_hci_smd_recv_event() function allocates memory with
    GFP_KERNEL which might sleep which can cause the interrupts
    not to be processed. This patch changes GFP_KERNEL to
    GFP_ATOMIC which prevents the function from sleeping
    while allocating memory.

    Revert "radio-tavarua: Configure search direction as passed by FM APP"

    As per V4L2 framework APP should pass the parameter as '1' to
    search in forward direction and '0' to search in downward
    direction. Reverting the change that was uploaded as it configured
    the search direction directly that it received it from the APP.
    APP should pass '1' for SEEK UP and '0' for SEEK DOWN . The driver
    should check for the direction before configuring. To the FM SOC,
    '0' means SEEK-UP and '1' means SEEK-DOWN. If APP passes '1' driver
    understands that user is requesting SEEK-UP operation and will
    configure the direction as '0'.

    This reverts commit 75b90b2359fe55e9e98906fbc088a32fe5537675

    <3>[   72.817173] fm_radio_shutdown: voting off failed with :(-512)
    RPC failure is because data to be sent from apps, was on behalf of the
    current process, but as the process is killed the current->pid given to
    rpc is a non-existing pid.
    To resolve the issue a valid pid is needed, which can be done by
    queueing a work in existing workqueue and wait for completion.

    radio: tavarua: Fix enum warnings

    The xfr_status variable is being read from an 8-bit unsigned register.
    Although the value definitions it is compared with are defined in an
    enum, these use bit arithmetic to define the cases (setting the high
    bit) which brings the constant values outside of the range of the
    enum.  This causes warnings on gcc 4.5.

    Fix this by keeping the value as an unsigned char.

    radio: tavarua: fixed low power support

    removed unnecessary i2c transaction to move between
    power modes when the requested power mode is already
    enabled. Changed the way the driver does user refernce
    count from atomic operations to semaphore synchronization.
    Also, disabled debugs.

    radio: tavura: Fix copy_from_user() warning

    The compiler is having a hard time determining that bytes_to_copy
    cannot be larger than XFR_REG_NUM. This causes a warning when
    strict user copy checks are enabled. Silence the warning by
    making bytes_to_copy unsigned, and use a more appropriate min
    function (min_t) on the bytes_left variable to help the compiler
    understand that the buffer will never overflow.

         gpu: ion: several bugfixes and enhancements of ION

         1. Verifying if the size of memory allocation in ion_alloc() is aligned
         by PAGE_SIZE at least. If it is not, this change makes the size to be
         aligned by PAGE_SIZE.

         2. Unmaps all mappings to the kernel and DMA address spaces when
         destroying ion_buffer in ion_buffer_destroy(). This prevents leaks in
         those virtual address spaces.

         3. Makes the return value of ion_alloc() to be explicit Linux error code
         when it fails to allocate a buffer.

         4. Makes ion_alloc() implementation simpler. Removes 'goto' statement and
         relavant call to ion_buffer_put().

         5. Checks if the task is valid before calling put_task_struct() due
         to failure on creating a ion client in ion_client_create().

         6. Returns error when buffer allocation requested by userspace is failed.

         This is necessary because in future updates the sg_table will be used

    media: video: Allow NR threshold to be updated by motion est

    VCAP did not allow for client to update threshold values based
    on the motion estimation. By enabling an option for this threshold
    to be updated dynamically by hardware, this allows for a more
    aggressive noise reduction to be applied at the request of the
    client.

     -Queues buffers
     -Close VCAP without ever calling stream on

    Since VCAP was not freeing ion this would cause a memory leak

    If a field was dropped by the VC, the VP would not be able to
    de-interlace the content properly. The problem with the VP is
    it would have an unbalanced number of top fields and bottom
    fields. In order to alleviate this problem the subsequent field
    will also be dropped. That way there would be a balanced number
    of top and bottom fields in the VP which would prevent jumping
    behavior observed in the de-interlaced frame.

    msm: mpq8064: Allow client to select num bufs for VC to hold onto

    VC part of the VCAP driver was initial implmented for the hardware
    to 2 store and work with 2 buffers. Since hardware is capable of
    storing and filling up to 6 buffers, a new API was created to allow
    client to select how many they want VC to use.

    msm: mpq8064: Correct VCAP shutdown procedure

    VCAP hardware shutdown sequence was incorrect. This would cause
    the hardware to become unstable, which would result in the system
    crashing. This patch corrects it so the driver calls the correct
    shutdown procedure.

    msm: mpq8064: Dummy read to prevent false interrupt from triggering

    The VBIF is capable of triggering a false bus error the first time
    it performs a read. This fix creates a dummy read event that
    happens every time that the VCAP is powered on that will ignore
    the false positive VBIF interrupt error, so that during normal
    operation the error can be properly identified.

    msm: mpq8064: VCAP corner case bug fixes

    Closing VCAP devices could be called without calling stream off:
    This problem would make VCAP resources taken by devices no longer
    running.

    Using unsigned variable to store signed result: This problem would
    allow stream on to continue even when function returned error.

    Fix problem of reading VP irq status register too early: It was
    possible for cadence detection bit to be propgated faster by only
    a few clock cycles then the picture done bit. When the irq status
    read was performed and by the time a write to the clear register
    was performed the picture done bit would propgate. Since the irq
    is rising edge triggered this would cause a problem and the irq
    would not be triggered until VP was reset.

    Remove unused code

    msm: mpq8064: Separate q/dq buffer for VCAP de-interlacing mode

    This change fixes a crash when running VCAP in de-interlace mode.
    The problem was noticed in the introduction of kernel 3.4. VCAP
    was improperly using the videobuf2 framework APIs. Since VCAP is
    already reliant on queue structure provided by videobuf2 framework,
    we created our own basic version of the qbuf and dqbuf calls that
    have some similarities to the videobuf2 framework. This addition
    was necessary since we are calling qbuf from a kernel work thread.
    Since moving to kernel 3.4 there has been a change in videobuf2
    qbuf that dereferences the current process.s mm_struct, from a
    kernel work thread this struct is NULL, which was causing a crash.
    When we are de-interlacing a captured video we are cycling the
    buffers internally in the driver, which is why we needed to create
    our own q/dq buffer functionality.

         gpu: ion: several bugfixes and enhancements of ION

         1. Verifying if the size of memory allocation in ion_alloc() is aligned
         by PAGE_SIZE at least. If it is not, this change makes the size to be
         aligned by PAGE_SIZE.

         2. Unmaps all mappings to the kernel and DMA address spaces when
         destroying ion_buffer in ion_buffer_destroy(). This prevents leaks in
         those virtual address spaces.

         3. Makes the return value of ion_alloc() to be explicit Linux error code
         when it fails to allocate a buffer.

         4. Makes ion_alloc() implementation simpler. Removes 'goto' statement and
         relavant call to ion_buffer_put().

         5. Checks if the task is valid before calling put_task_struct() due
         to failure on creating a ion client in ion_client_create().

         6. Returns error when buffer allocation requested by userspace is failed.
