The media_entity_cleanup() function belong to the module cleanup handlers, not the entity registration handlers. Move it there. Create a omap3isp_video_cleanup() function to cleanup the video node entity, and call it from the module cleanup handlers. Rename omap3isp_stat_free() to omap3isp_stat_cleanup(). Signed-off-by:

This driver exposes preview mode operation of the S5K6AAFX sensor with embedded SoC ISP. The native capture (snapshot) operation mode is not supported. Following controls are available: manual/auto exposure and gain, power line frequency (anti-flicker), saturation, sharpness, brightness, contrast, white balance temperature, color effects, horizontal/vertical image flip, frame interval, auto white balance. RGB component gains are currently exposed through private controls. Reviewed-by:

V4L2_CID_POWER_LINE_FREQUENCY control allows applications to instruct a driver what is the power line frequency so an appropriate filter can be used by the device to cancel flicker by compensating the light intensity ripple. Currently in the menu we have entries for 50 Hz and 60 Hz and for entirely disabling the anti-flicker filter. However some devices are capable of automatically detecting the frequency, so add V4L2_CID_POWER_LINE_FREQUENCY_AUTO entry for them. Signed-off-by:

* with no "retrun ret;" at the end, there is no need to initialize ret any longer, * consequently use conditional expressions, not if...else constructs, throughout ov6650_s_ctrl(), * v4l2_ctrl_new_std_menu() max value of V4L2_EXPOSURE_MANUAL instead of equivalent 1 looks more clear. Created on top of "Converting soc_camera to the control framework" series. Signed-off-by:

This patch adds the ability to get arbitrary resolutions with a width up to 2592 and a height up to 720 pixels instead of the standard 1280x720 only. Signed-off-by:

Most users of the <media/soc_mediabus.h> header only need pixel code definitions, which are now located in the generic <linux/v4l2-mediabus.h> header. Switch over to reduce soc-camera dependencies. Signed-off-by:

The most important change in this patch is direct linking to struct soc_camera_link via the client->dev.platform_data pointer. This makes most of the soc-camera client drivers also usable outside of the soc-camera framework. After this change all what is needed for these drivers to function are inclusions of soc-camera headers for some convenience macros, suitably configured platform data, which is anyway always required, and loaded soc-camera core module for library functions. If desired, these library functions can be made generic in the future and moved to a more neutral location. The only two client drivers, that still depend on soc-camera are: mt9t031: it uses struct video_device for its PM. Since no hardware is available, alternative methods cannot be tested. ov6650: it uses struct soc_camera_device to pass its sense data back to the bridge driver. A generic v4l2-subdevice approach should be developed to perform this. Signed-off-by:

VIDIOC_G_STD can return the current TV-norm to the user in one of two ways: if an .vidioc_g_std() ioctl operation is provided by the driver, it is called, otherwise the value ot the .current_norm field of struct video_device is returned. Since subdevice drivers currently have no access to struct video_device objects, the only way to provide this information to the user is by implementing a .g_std() method. Signed-off-by:

Currently only very few drivers actually use video_device nodes, embedded in struct v4l2_subdev. Allocate these nodes dynamically for those drivers to save memory for the rest. Signed-off-by:

If the sh_mobile_csi2 driver didn't attach to a client, normally, because the respective device connects to the SoC over the parallel CEU interface and doesn't use the CSI-2 controller, it also shouldn't call pm_runtime_put() on attempted disconnect. Signed-off-by:

Using the internally cached pixel code, instead of the one, provided by the soc-camera, removes one more use of struct soc_camera_device in these drivers. Also remove the no longer needed soc_camera_from_i2c() inline function. Signed-off-by:

Remove most trivial uses of struct soc_camera_device from most client drivers, abstracting some of them inside inline functions. Next steps will eliminate remaining uses and modify inline functions to not use struct soc_camera_device. Signed-off-by:

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:

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:

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:

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.
