[media] V4L: Add driver for S3C24XX/S3C64XX SoC series camera interface

2012-11-28T11:43:34Z

This patch adds V4L2 driver for Samsung S3C24XX/S3C64XX SoC series camera interface. The driver exposes a subdev device node for CAMIF pixel resolution and crop control and two video capture nodes - for the "codec" and "preview" data paths. It has been tested on Mini2440 (s3c2440) and Mini6410 (s3c6410) board with gstreamer and mplayer.

[media] v4l: vb2: add support for shared buffer (dma_buf)

2012-11-25T19:11:12Z

This patch adds support for DMABUF memory type in videobuf2. It calls relevant APIs of dma_buf for v4l reqbuf / qbuf / dqbuf operations. For this version, the support is for videobuf2 as a user of the shared buffer; so the allocation of the buffer is done outside of V4L2.

[media] mt9v022: set y_skip_top field to zero as default

2012-11-22T13:36:50Z

Set "y_skip_top" to zero and revise comment as I do not see this line corruption on two different mt9v022 setups. The first read-out line is perfectly fine. Add mt9v022 platform data configuring y_skip_top for platforms that have issues with the first read-out line. Set y_skip_top to 1 for pcm990 board.

[media] adv7604: Replace prim_mode by mode

2012-11-21T19:43:49Z

Changes the way the primary mode is handled: - Remove it from platform_data since it doesn't belong there. - Add a new mode enum for use with s_routing. - Collapse the two HDMI modes into one HDMI mode: when setting up the timings manually we do not need to select HDMI_COMP mode. That's only needed when selecting a preset. This patch prepares for the next step where we switch to using the presets where available.
