The core driver can now operate in either vmalloc or dma-contig modes; obviously the latter is preferable when it is supported. Default is currently vmalloc on all platforms; load the module with buffer_mode=1 for contiguous DMA mode.

This was an old debugging thing from years ago. It's only done at initialization time, but it's still unnecessary; take it out. Signed-off-by: Jonathan Corbet <corbet@lwn.net> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

This is a basic, naive conversion to the videobuf2 infrastructure, removing a lot of code in the process. For now, we're using vmalloc, which is suboptimal, but it does match what the cafe driver did before. In the cafe case, it may have to stay that way just because memory is too tight to do direct streaming; mmp-camera will be able to do better.

This patch adds the VENC or the Video encoder, which is responsible for the blending of all source planes and timing generation for Video modes like NTSC, PAL and other digital outputs. the VENC implementation currently supports COMPOSITE and COMPONENT outputs and NTSC and PAL resolutions through the analog DACs. The venc block is implemented as a subdevice, allowing for additional external and internal encoders of other kind to plug-in.

This patch implements the functionality of the OSD block of the VPBE. The OSD in total supports 4 planes or Video sources - 2 mainly RGB and 2 Video. The patch implements general handling of all the planes, with specific emphasis on the Video plane capabilities as the Video planes are supported through the V4L2 driver.

This patch implements the core functionality of the display driver, mainly controlling the VENC and other encoders, and acting as the one point interface for the main V4L2 driver. This implements the core of each of the V4L2 IOCTLs.

This is the display driver for Texas Instruments's DM644X family SoC. This patch contains the main implementation of the driver with the V4L2 interface. The driver implements the streaming model with support for both kernel allocated buffers and user pointers. It also implements all of the necessary IOCTLs necessary and supported by the video display device.

Mark the alsa stream with SNDRV_PCM_INFO_BATCH, as the timing to get audio streams can vary.

Export ac97 volume controls via mixer. Pulseaudio will probably handle it very badly, as it has no idea about how volumes are wired, and how are they associated with each TV input. Those wirings are card model dependent, and we don't have the wiring mappings for each supported device. Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
