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.

* core.c has implemented the platform driver methods, file operations and v4l2 registration. * helpers.c has implemented common helper functions for: - buffer management - vb2_ops and functions for format propagation, - functions for allocating and freeing buffers for internal usage. The buffer parameters describing internal buffers depends on current format, resolution and codec. - functions for calculation of current load of the hardware. Depending on the count of instances and resolutions it selects the best clock rate for the video core. * firmware loader Signed-off-by:

-
Sakari Ailus authored
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:

Calling S_STREAM OFF multiple times on a video device is valid, although dubious, practice. Instead of warning about it and setting stream count lower than zero, just ignore the subsequent S_STREAM calls and correct the stream count to zero. 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:

Move the crop rectangle to the sink pad and add a sink compose rectangle to configure scaling. Also propagate rectangles from sink pad to crop rectangle, to compose rectangle, and to the source pads both in ACTIVE and TRY variants of set_fmt/selection, and initialize the default crop and compose rectangles.

The CSI can skip any out of up to 6 input frames, allowing to reduce the frame rate at the output pads by small fractions. Signed-off-by:

Bayer formats must be treated as generic data and passthrough mode must be used. Add the correct setup for these formats. - added check to csi_link_validate() to verify that destination is IDMAC output pad when passthrough conditions exist: bayer formats and 16-bit parallel buses. Signed-off-by:

Adds MIPI CSI-2 Receiver subdev driver. This subdev is required for sensors with a MIPI CSI2 interface. - Switch from the v4l2_of_ APIs to the v4l2_fwnode_ APIs. - Add the function csi2ipu_gasket_init() to initialize the gasket at s_power(ON). The gasket needs to be programmed with the correct color component ordering to handle UYVY vs. YUYV ordered mbus formats from sensors. Note that the description of the CSI2IPU_GASKET register in the i.MX6 reference manual is wrong w.r.t bit 2 (the manual refers to this register as CSI2_SW_RST): setting bit 2 selects YUYV order, not UYVY.

This is a set of three media entity subdevice drivers for the i.MX Image Converter: - Pre-process Router: Takes input frames from CSI0, CSI1, or VDIC. Two output pads enable either or both of the preprocess tasks below. If the input is from one of the CSIs, both proprocess task links can be enabled to process frames from that CSI simultaneously. If the input is the VDIC, only the Pre-processing Viewfinder task link can be enabled. - Pre-processing Encode task: video frames are routed directly from the CSI and can be scaled, color-space converted, and rotated. Scaled output is limited to 1024x1024 resolution. Output frames are routed to the prpenc capture device. - Pre-processing Viewfinder task: this task can perform the same conversions as the pre-process encode task, but in addition can be used for hardware motion compensated deinterlacing. Frames can come either directly from the CSI or from the VDIC. Scaled output is limited to 1024x1024 resolution. Output frames are routed to the prpvf capture device. Signed-off-by:

This is a media entity subdevice driver for the i.MX Video De-Interlacing or Combining Block. So far this entity does not implement the Combining function but only motion compensated deinterlacing. Video frames are received from the CSI and are routed to the IC PRPVF entity. Signed-off-by:

This is a media entity subdevice for the i.MX Camera Sensor Interface module. - Added support for negotiation of frame intervals. - Fixed cropping rectangle negotiation at input and output pads. - Added support for /2 downscaling, if the output pad dimension(s) are 1/2 the crop dimension(s) at csi_setup() time.

This is the capture device interface driver that provides the v4l2 user interface. Frames can be received from various sources: - directly from CSI for capturing unconverted images directly from camera sensors. - from the IC pre-process encode task. - from the IC pre-process viewfinder task.
