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:

All soc-camera host drivers include a pointer to an soc-camera device in their host private struct to check, that only one client is connected. Move this common code to soc_camera.c. Signed-off-by:

This patch removes the driver_data member from ths7303_state structure. The driver_data member was intended to differentiate between ths7303 and ths7353 chip and get the g_chip_ident, But as of now g_chip_ident is obsolete, so there is no need of driver_data. Signed-off-by:

1. usbvision->alt_max_pkt_size is not deallocated anywhere. 2. if allocation of usbvision->alt_max_pkt_size fails, there is no proper deallocation of already acquired resources. The patch adds kfree(usbvision->alt_max_pkt_size) to usbvision_release() as soon as other deallocations happen there. It calls usbvision_release() if allocation of usbvision->alt_max_pkt_size fails as soon as usbvision_release() is safe to work with incompletely initialized usbvision structure.
