The sh_mobile_ceu_camera driver implements a generic algorithm for setting up an optimal client and host scaling and cropping configuration. This patch makes those functions available for all drivers. Signed-off-by:

Guennadi Liakhovetski authored
Several functions in the sh_mobile_ceu_camera driver implement generic algorithms and can be re-used by other V4L2 camera host drivers too. These functions attempt to optimise scaling and cropping functions of the subdevice, e.g. a camera sensor. This patch makes those functions generic for future re-use by other camera host drivers.

Use the v4l2-async API to support asynchronous subdevice probing, including the CSI2 subdevice. Synchronous probing is still supported too. Signed-off-by:

Guennadi Liakhovetski authored
Add support for asynchronous subdevice probing, using the v4l2-async API. The legacy synchronous mode is still supported too, which allows to gradually update drivers and platforms. The selected approach adds a notifier for each struct soc_camera_device instance, i.e. for each video device node, even when there are multiple such instances registered with a single soc-camera host simultaneously.

Instead of centrally enabling and disabling subdevice master clocks in soc-camera core, let subdevice drivers do that themselves, using the V4L2 clock API and soc-camera convenience wrappers. Signed-off-by:

Currently bridge device drivers register devices for all subdevices synchronously, typically, during their probing. E.g. if an I2C CMOS sensor is attached to a video bridge device, the bridge driver will create an I2C device and wait for the respective I2C driver to probe. This makes linking of devices straight forward, but this approach cannot be used with intrinsically asynchronous and unordered device registration systems like the Flattened Device Tree. To support such systems this patch adds an asynchronous subdevice registration framework to V4L2. To use it respective (e.g. I2C) subdevice drivers must register themselves with the framework. A bridge driver on the other hand must register notification callbacks, that will be called upon various related events. Signed-off-by:

It is often useful to have simple means to get from a subdevice to the underlying physical device. This patch adds such a pointer to struct v4l2_subdev and sets it accordingly in the I2C and SPI cases. Signed-off-by:

Guennadi Liakhovetski authored
Typical video devices like camera sensors require an external clock source. Many such devices cannot even access their hardware registers without a running clock. These clock sources should be controlled by their consumers. This should be performed, using the generic clock framework. Unfortunately so far only very few systems have been ported to that framework. This patch adds a set of temporary helpers, mimicking the generic clock API, to V4L2. Platforms, adopting the clock API, should switch to using it. Eventually this temporary API should be removed. Signed-off-by:

All existing soc-camera host drivers use .clock_start() and .clock_stop() callbacks to activate and deactivate their camera interfaces, whereas .add() and .remove() callbacks are usually dummy. Make the former two compulsory and the latter two optional. Signed-off-by:

When adding and removing a client, the sh-mobile-ceu-camera driver activates and, respectively, deactivates its camera interface and, if necessary, the CSI2 controller. Only handling of the CSI2 interface is client-specific and is only needed, when a data-exchange with the client is taking place. Move the rest to .clock_start() and .clock_stop() callbacks.

Currently soc-camera uses a single camera host callback to activate the interface master clock and to configure the interface for a specific client. However, during probing we might not have the information about a client, we just need to activate the clock. Add new camera host driver callbacks to only start and stop the clock without and client-specific configuration. Signed-off-by:
