While the h.264 standard only allows up to 16 reference frames, the CODA firmware needs two more buffers: one to hold the currently decoded frame and one for the display frame. Adding the framebuffer needed by the driver for VDOA operation brings the total to a maximum of 19 internal framebuffers. Lift the current maximum of 17 internal framebuffers to allow playback of high profile streams that require more than 14 reference frames. Signed-off-by:

After the move of videobuf2 into the common directory, selecting the au0828 driver with CONFIG_V4L2 disabled started causing a link failure, as we now attempt to build videobuf2 but it still requires v4l2: ERROR: "v4l2_event_pending" [drivers/media/common/videobuf/videobuf2-v4l2.ko] undefined! ERROR: "v4l2_fh_release" [drivers/media/common/videobuf/videobuf2-v4l2.ko] undefined! ERROR: "video_devdata" [drivers/media/common/videobuf/videobuf2-v4l2.ko] undefined!

ERROR: "v4l_vb2q_enable_media_source" [drivers/media/common/videobuf/videobuf2-core.ko] undefined! We want to be able to build the core au0828 support without V4L2, so this makes the 'select' conditional on V4L2, and refines the dependencies in VIDEO_AU0828_V4L2 so it can only be enabled in the exact conditions that have VIDEOBUF2_VMALLOC reachable.

ov7670 driver supports two optional properties supplied through platform data, but currently does not support any standard video interface property. Add support through OF parsing for 2 generic properties (vsync and hsync polarities) and for one custom property already supported through platform data to suppress pixel clock output during horizontal blanking. While at there, check return value of register writes in set_fmt function and rationalize spacings. Signal polarities and pixel clock blanking verified through scope and image capture. Signed-off-by:

The ov9650 driver currently only supports legacy platform data probe. This change adds device tree probing. There has been an attempt to add device tree support for ov9650 driver by Hugues Fruchet as a part of the patchset that adds support of OV9655 camera (http://www.spinics.net/lists/linux-media/msg117903.html), but it wasn't merged into mainline because creating a separate driver for OV9655 is preferred. This is very similar to Hugues's patch, but not supporting new device. Cc: Jacopo Mondi <jacopo@jmondi.org> Cc: H.

Commit 828ee8c7 ("media: uvcvideo: Use ktime_t for timestamps") changed to use ktime_t for timestamps. Older Kernels use a struct for ktime_t, which requires the conversion function ktime_to_ns to be used on some places. With this patch it will compile now also for older Kernel versions.

While the sizeof is an operator and not a function, the preferred coding style in the kernel is to enclose its operand in parentheses. To avoid mixing multiple coding styles in the driver, use parentheses around all sizeof operands.

Use flags the device exposes for UVC controls. This allows the device to define which property flags are set. Since some cameras offer auto-adjustments for properties (e.g. auto-gain), the values of other properties (e.g. gain) can change in the camera. Examining the flags ensures that the driver is aware of such properties. Signed-off-by:
