The optional operation can be used by entities to report how it maps its
fwnode endpoints to media pad numbers. This is useful for devices which
require advanced mappings of pads.Signed-off-by: Niklas Söderlund

The davinci VPIF is a single hardware block, but the existing driver
is broken up into a common library (vpif.c), output (vpif_display.c) and
intput (vpif_capture.c).When migrating to DT, to better model the hardware, and because
registers, interrupts, etc. are all common,it was decided to
have a single VPIF hardware node[1].Because davinci uses legacy, non-DT boot on several SoCs still, the
platform_drivers need to remain. But they are also needed in DT boot.
Since there are no DT nodes for the display/capture parts in DT
boot (there is a single node for the parent/common device) we need to
create platform_devices somewhere to instantiate the platform_drivers.When VPIF display/capture are needed for a DT boot, the VPIF node
will have endpoints defined for its subdevs. Therefore, vpif_probe()
checks for the presence of endpoints, and if detected manually creates
the platform_devices for the display and capture platform_drivers.[1] Documentation/devicetree/bindings/media/ti,da850-vpif.txt

As long as only one CODA context is running we get alternating device_run()
and wait_for_completion() calls, but when more then one CODA context is
active, other VDOA slots can be inserted between those calls for one context.Make sure to wait on job completion before running a different context and
before destroying the currently active context.Signed-off-by: Lucas Stach

This implements a simple handler for the case where decode did not finish
sucessfully. This might be helpful during normal streaming, but for now it
only handles the case where the context would deadlock with userspace,
i.e. userspace issued DEC_CMD_STOP and waits for EOS, but after the failed
decode run we would hold the context and wait for userspace to queue more
buffers.Signed-off-by: Lucas Stach

This adds support for V4L2_CID_MIN_BUFFERS_FOR_CAPTURE get control
in venus decoder, it is usable in case when the userspace wants
to know minimum capture buffers before calling request_buf for

This adds Venus driver Makefile and changes v4l2 platform
Makefile/Kconfig in order to enable building of the driver.Note that in this initial version the COMPILE_TEST-ing is not
supported because the drivers specific to ARM builds are still
in process of enabling the aforementioned compile testing.
Once that disadvantage is fixed the Venus driver compile testing
will be possible with follow-up changes.Signed-off-by: Stanimir Varbanov

and encoder parts to comunicate with the firmware. For example
there are functions for session and core initialisation.- hfi_cmds has packetization operations which preparing

colorimetry parameters.If the field order is set to ANY, choose the currently set field order
at the sink pad. If the colorspace is set to DEFAULT, choose the
current colorspace at the sink pad. If any of xfer_func, ycbcr_enc
or quantization are set to DEFAULT, either choose the current sink pad
setting, or the default setting for the new colorspace, if non-DEFAULT
colorspace was given.If a format is destined to be routed through the Image Converter,
fixed quantization and Y`CbCr encoding must be set.Colorimetry is also propagated from sink to source pads anywhere
this has not already been done.Signed-off-by: Steve Longerbeam
