The try_mbus_fmt video op is a duplicate of the pad op. Replace all uses in sub-devices by the set_fmt() pad op. Since try_mbus_fmt and s_mbus_fmt both map to the set_fmt pad op (but with a different 'which' argument), this patch will replace both try_mbus_fmt and s_mbus_fmt by set_fmt. Signed-off-by:

In order to have subsytem agnostic media bus format definitions we've moved media bus definitions to include/uapi/linux/media-bus-format.h and prefixed values with MEDIA_BUS_FMT instead of V4L2_MBUS_FMT. Replace all references to the old definitions in i2c drivers. Signed-off-by:

Commit 0ba2aeb6 increased the internal control ranges to 64 bit, but that caused problems in drivers that use the minimum/maximum/step/default_value control values in a division or modulus operations since not all architectures support those natively. Luckily, in almost all cases it is possible to just cast to 32 bits (the control value is known to be 32 bits, so it is safe to cast). Only in v4l2-ctrls.c was it necessary to use do_div in one function. Signed-off-by:

Several client drivers access the hardware at probe time, for instance to read the probe chip ID. Such chips need to be powered up when being probed. soc-camera handles this by powering chips up in the soc-camera probe implementation. However, this will break with non soc-camera hosts that don't perform the same operations. Fix the problem by pushing the power up/down from the soc-camera core down to individual drivers on a needs basis. Signed-off-by:

Instead of forcing all soc-camera drivers to go through the mid-layer to handle power management, create soc_camera_power_[on|off]() functions that can be called from the subdev .s_power() operation to manage regulators and platform-specific power handling. This allows non soc-camera hosts to use soc-camera-aware clients. 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:

Guennadi Liakhovetski authored
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:

I2C drivers can use the clientdata-pointer to point to private data. As I2C devices are not really unregistered, but merely detached from their driver, it used to be the drivers obligation to clear this pointer during remove() or a failed probe(). As a couple of drivers forgot to do this, it was agreed that it was cleaner if the i2c-core does this clearance when appropriate, as there is no guarantee for the lifetime of the clientdata-pointer after remove() anyhow. This feature was added to the core with commit e4a7b9b0 to fix the faulty drivers. As there is no need anymore to clear the clientdata-pointer, remove all current occurrences in the drivers to simplify the code and prevent confusion. Signed-off-by:

If the platform hooks are provided, soc_camera powers off the device on close and powers it on on open. This resets the ADDRESS_MODE registers which then can be different to the value the driver has computed for them. This patch setups runtime pm usage for mt9t031 and uses the resume function to write the ADDRESS_MODE registers in order to fix the above described problem. Signed-off-by:

The initial soc-camera scaling and cropping implementation turned out to be incompliant with the V4L2 API, e.g., it expected the user to specify cropping in output window pixels, instead of input window pixels.
