There can be situations when opening camera will fail, not
due to an error but due to the fact that the current hardware
configuration can only support either the front or back camera
and can't support opening another the camera at the moment.
In such cases, rather than returning -EFAULT to user space, camera
should return -EBUSY so as to distinguish between a genuine failure
to open the camera and a failure due to current configuration which
precludes from opening another instance of the camera.
So, correct the return code in the camera open failure handling code.

When sof freeze happens, before notifying hal, backend
now notifies kernel. This helps us in contacting all the
sub devices and printing the required information to
understand why freeze happened.

pmic and i2c based flash use common driver.
Single driver handles all types of flashes
like i2c based / pmic based / strobe flash
unlike previous driver.
Receives same ioctls from userspace to control
the flash hardware for all types of flashes.
Flash driver is driven from usersapce like
the previous implementation.

struct v4l2_event should not be used for communication via
private ioctl because v4l2_event type is meant only for communication
through the V4L2 framework. Using this outside the framework for
custom ioctls will result in improper handling when 32/64 conversion
are needed.
So change the private ioctl handler in msm.c to not use this struct.
Also update the ioctl codes to use msm_v4l2_event_data instead of
v4l2_event.

In current sensor architecture, one platform device is created for
every sensor defined in dtsi for that platform. It creates redundancy
since only one camera can be connected in camera slot for particular
target. To avoid this redundancy, create platform device for every
camera slot for that platform and probe using single compatible name
"qcom,camera" for all drivers. Add sensor utility functions to be
used by all camera sensors.

The parameter for number of buffers passed from user space
may be very large. While allocating memory, this could result
in integer overflow. As a result lesser memory will be allocated
then expected. This inturn may result in array index out of bound
error when the pointer is used to access memory.
The fix is to limit the maximum requested buffers per stream. If
request is greater than the maximum value, error is returned back
to user space.

with the s_ctrl ioctl is passed along to the back-end
along with the rest of the event. Also, the return value

Camera sensor driver architecture is redesigned to have move control
at user space. The current kernel driver has provision for probing
to find whether a particular camera sensor is connected. A video node
is created for every successful camera probe. This request consists of
samsung S5K3L1YX 12 MP sensor driver, CCI (Camera Control Interface)
driver to perform I2C calls on I2C master bus, I2C MUX driver to select
2D / 3D MUX, QUP driver to perform legacy I2C calls and other utility
functions (msm_sensor) that can be reused by kernel sensor drivers.

This change reimplements MSM camera V4L2 driver for camera
2.0. Current architecture cannot support 2.0 API very well.
This initial change contains plumbing code for v4l2 device
node creation, ioctls, events, videobuf2, etc.
The new code avoids payload deep-copy by passing them
between user space processes via IPC.
