Add a check for v4l2_dev to v4l2_async_notifier_register() as to fail as early as possible since this will fail later in v4l2_async_test_notify(). Signed-off-by:

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.

'call_ptr_memop' can return NULL, so we must test its return value with 'IS_ERR_OR_NULL'. Otherwise, the test 'if (mem_priv)' is meaningless. Signed-off-by:

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:

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.

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 capture queue in mem2mem drivers. Also this will fix an issue found gstreamer v4l2videodec element, i.e. the video decoder element cannot continue because the buffers are insufficient. Signed-off-by:

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:

This is the implementation of HFI. It is charged with the responsibility to comunicate with the firmware through an interface commands and messages. - hfi.c has interface functions used by the core, decoder 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 packets to be send from host to firmware. - hfi_msgs takes care of messages sent from firmware to the host.

The buffer parameters describing internal buffers depends on current format, resolution and codec. - functions for calculation of current load of the hardware.

Add V4L2_CID_DIGITAL_GAIN to control explicitly digital gain. We already have analogue gain control which the digital gain control complements. Typically higher quality images are obtained using analogue gain only as the digital gain does not add information to the image (rather it may remove it). Signed-off-by:

This patch adds a call to imx_media_fill_default_mbus_fields() in the *_try_fmt() functions at the sink pads, to set empty field order and 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:

Russell King authored
Add frame size and frame interval enumeration to CSI. CSI can downscale the image independently horizontally and vertically by a factor of two, which enumerates to four different frame sizes at the output pads. The input pad supports a range of frame sizes. CSI can also drop frames, resulting in frame rate reduction, so enumerate the resulting possible output frame rates. Signed-off-by:
