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.

When adding and removing a client, the mx1-camera driver only activates

any client-specific actions. Move this functionality into .clock_start()

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.

3.11 is approaching... Here comes v10 of the V4L2 clock helper and
asynchronous probing patch set. In this series I included 3 groups of
patches, that actually aren't that strongly related.
1. patches 1-11 split soc-camera subdevice linking procedure into two
steps: (a) turning on the master
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
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,
During client probing we only have to turn on the host's clock, no need to
actually attach the client to the host.

Register the imx074 camera I2C and the CSI-2 platform devices directly
in board platform data instead of letting the sh_mobile_ceu_camera driver
and the soc-camera framework register them at their run-time. This uses
the V4L2 asynchronous subdevice probing capability.

All soc-camera host drivers include a pointer to an soc-camera device in

It is often useful to have simple means to get from a subdevice to the

v4l2_subdev and sets it accordingly in the I2C and SPI cases.

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

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.

Currently bridge device drivers register devices for all subdevices
synchronously, tupically, during their probing. E.g. if an I2C CMOS sensor

Hello Paulo
Thank you for your quick response.
Unfortunately if I select YUYV or any other format that is not MJPG data flow

Does this represent a bug in either the webcam's UVC support or the UVC driver?
If so I presume there is no likely quick
Hi,
You should select YUYV before disabling the video processing.
So with video processing still enabled:
