The added HDMI CEC framework provides a generic kernel interface for
HDMI CEC devices.Note that the CEC framework is added to staging/media and that the
cec.h and cec-funcs.h headers are not exported yet. While the kABI
is mature, I would prefer to allow the uABI some more time before
it is mainlined in case it needs more tweaks.This adds the cec-api.c source that deals with the public CEC API
and the Kconfig/Makefile plumbing.The MAINTAINERS file is also updated.

is disabled, drivers will still need these functions. Which is the

list of supported DV timings for that pad.Commit bd3e275f3ec0 ("[media] media: i2c: adv7604: Use v4l2-dv-timings

The power_on function of the driver resets the chip and sets the
CHIP_CONTROL register to 0. This switches the operating mode to slave.
The s_stream function sets the correct mode. But this caused problems on
a board where the camera chip is operated as master. The camera started
after a random amount of time streaming an image, I observed between 10
and 300 seconds.The STRFM_OUT and STLN_OUT pins are not connected on this board which
may cause some issues in slave mode. I could not find any documentation
about this.Keeping the chip in master mode after the reset helped to fix this
issue for me.Signed-off-by: Markus Pargmann

Audio hw params are shared across all DMA channels,
so if the user changes any of these while any DMA channel is
enabled, it will impact the enabled channels, potentially causing
serious instability issues.This commit avoids such situation, by preventing any hw param
change (on any DMA channel) if any other DMA audio channel is capturing.Signed-off-by: Ezequiel Garcia

Currently, the driver has a fixed period size of 4096 bytes
(2048 frames). Since this hardware can configure the audio
capture size, this commit allows a period size range of [512-4096].This is very useful to reduce the audio latency.

Now that we've introduced the dma_mode parameter to pick the
DMA operation, let's use it to also select the audio DMA
operation.When dma_mode != memcpy, the driver will avoid using memcpy
in the audio capture path, and the DMA hardware operation
will act directly on the ALSA buffers.Signed-off-by: Ezequiel Garcia

Now that the driver has the infrastructure to support more

Now that the driver has the infrastructure to support more
DMA modes, let's add the DMA contiguous interlaced frame mode.In this mode, the DMA P and B buffers are programmed with
the user-provided buffers. When a P (or B) frame is ready,
a new buffer is dequeued into P (or B).In addition to interlaced fields, the device can also be
programmed to deliver alternate fields. Only interlaced
mode is supported for now.Tested-by: Tim Harvey

Let's set the corner stone to support all the DMA modes
available on this device.For stability reasons, the driver is currently setting DMA frame
mode, and using single DMA buffers to get the P and B buffers.
Each frame is then memcpy'ed into the user buffer.However, other platforms might be interested in avoiding this
memcpy, or in taking advantage of the chip's DMA scatter-gather
capabilities.To achieve this, this commit introduces a "dma_mode" module parameter,
and a tw686x_dma_ops struct. This will allow to define functions to
alloc/free DMA buffers, and to return the frames to userspace.The memcpy-based method described above is named as dma_mode="memcpy".
Current alloc/free functions are renamed as tw686x_memcpy_xxx,
and are now used through a memcpy_dma_ops.Tested-by: Tim Harvey
