This commit resolves an issue of non-working vi camera driver
on Colibri T20 occured after a l4t-r16-r4 merge.
|
|
This commit restores the full framerate (25 FPS), after a drop to
16 FPS caused by a l4t-r16-r4 merge.
|
|
This commit adds settings such as:
- values of horizontal/vertical active start,
- enabling/disabling internal sync,
to the private data of decoders: MAX9526, ADV7180, TVP5150,
OV7670 and AS0260.
The feature is available through *_tegra_camera_platform_data
struct initialised in board-*.c files.

soc_camera_link supports passing power on/off control callback to
soc_camera stack. So the power control can be handled by soc_camera
stack instead of our Tegra V4L2 host driver.
Also pass other platform_data fields via soc_camera_link instead of
a hacking nvhost_device_data struct.

CSI host controller of Tegra can support Bayer Raw8 and Raw 10 data
input, it also output data as extended 16-bit data format in memory
directly.
Raw data output should be handled by the second output channel.
This patch add supporting for Raw data input/output and the second
output channel.
All were tested on Cardhu board.

Function pointer int (*queue_setup)() of struct vb2_ops in
include/media/videobuf2-core.h is not compatible with our function
call tegra_camera_videobuf_setup(). So building will generate warning
and it will cause alloc_ctxs[] with wrong value, then introduce
memory access oops later.
