Currently soc-camera can use power regulators and platform specific methods to power clients up and down. Additionally, client drivers can provide their own subdevice .s_power() methods, acting directly on the device. This patch adds calls to this method, when external power supplies are on.

The life-time of soc-camera device objects can be longer, than the time, it is attached to a client driver, therefore all references to the driver own data have to be cleared, when the driver is detached. Signed-off-by:

The soc_camera_power_set() function processes two cases: power on anf off. These two cases don't share and common code, and the function is always called with a constant power on / off argument. Splitting this function into two removes a condition check, reduces indentation levels and makes the code look cleaner. Signed-off-by:

We do not have to scan the list of subdevices to find our client - the sensor, the host has already set our grp_id value. Signed-off-by:

It is a task of the host / bridge driver to bind single subdevices into a pipeline, not of respective subdevices. Eventually this might be handled by the Media Controller API. Signed-off-by:

This patch adds two new ioctl() handlers: .vidioc_create_bufs() and .vidioc_prepare_buf() for compliant vb2 soc-camera hosts. Signed-off-by:

Prepare the mx3_camera friver to support the new VIDIOC_CREATE_BUFS and VIDIOC_PREPARE_BUF ioctl()s. The .queue_setup() vb2 operation must be able to handle buffer sizes, provided by the caller, and the .buf_prepare() operation must not use the currently configured frame format for its operation, which makes it superfluous for this driver. Its functionality is moved into .buf_queue(). Signed-off-by:

And since this is the last and only host driver that uses controls, also remove the now obsolete control fields from soc_camera.h. Signed-off-by:

The soc_camera framework is switched over to use the control framework. After this patch none of the controls in subdevs or host drivers are available, until those drivers are also converted to the control framework. Signed-off-by:

To support multi-size buffers in the mx3_camera V4L2 driver we have to be able to stop DMA on a channel without releasing descriptors and completely halting the hardware. Use the DMA_PAUSE control to implement this mode. Signed-off-by:

The two recently added ioctl()s VIDIOC_CREATE_BUFS and VIDIOC_PREPARE_BUF allow user-space applications to allocate video buffers of different sizes and hand them over to the driver for fast switching between different frame formats. This patch adds support for buffers of different sizes on the same buffer-queue to vb2. Signed-off-by:

V4L2 specification states, that the videobuffer state flags have to be updated on VIDIOC_QBUF ioctl(). Videobuf2 currently doesn't do that, which is fixed by this patch. Signed-off-by:

A possibility to preallocate and initialise buffers of different sizes in V4L2 is required for an efficient implementation of a snapshot mode. This patch adds two new ioctl()s: VIDIOC_CREATE_BUFS and VIDIOC_PREPARE_BUF and defines respective data structures. Signed-off-by:

The current sh_mobile_ceu_camera driver can cause an Oops, if a CSI2 and a parallel camera are registered on the same CEU. Fix it by making CSI2 association with a camera more targeted. Signed-off-by:

G_CROP, S_CROP, CROPCAP, G_FMT, and S_FMT functionality in the mt9t112 driver was broken on many occasions. This patch allows consistent cropping for rectangles also larger than VGA and cleans up multiple other issues in this area. It still doesn't add support for proper scaling, using the sensor own scaler, so input window is still always equal to the output frame. Signed-off-by:
