Hi Mauro,
Great news, please count me in. We are currently building a new
ChromeOS graphics/media stack based on V4L2, vb2, dmabuf, DRM and GL.
Synchronization/shared resource usage is one important topic for
discussion, as well as, depending on interest, perhaps optimizations
like CPU cache

Initial version of this driver.
The full datasheets are available from the Analog Devices website:
http://ez.analog.com/docs/DOC-1741
Not all features of the receiver are supported by this driver for various
reasons. Most notably:
- No CEC support (the CEC API needs a lot more discussion)
-
These two helper functions detect whether the analog video timings detected
by the video receiver match the VESA CVT or GTF standards.
They basically do the inverse of the CVT and GTF modeline calculations.
This patch also adds a helper function that will determine the aspect ratio

Here's the third version of the miscellaneous soc-camera patches that try to

As with the previous version, all patches have been compile-tested but not
runtime-tested as I lack the necessary hardware.

The .s_power() call only covers the .g_mbus_fmt() operation call.

anymore and can be removed.

Powering off a device is a best effort task: failure to execute one of
the steps should not prevent the next steps to be executed. For
instance, an I2C communication error when putting the chip in stand-by
mode should not prevent the more agressive next step of turning the
chip's power supply off.
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
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
There will be no soc_camera_device instance with a soc-camera device is
used with a non soc-camera host, so we won't be able to pass the
soc_camera_device fake platform device to board code. Pass the physical
device instead.
The argument is currently not used by any board file so this is safe.
Hi,
Here's the second version of the ov772x cleanup and fixes patches. They apply

- Add
