The SUB submodules are a part of the atmel-isc pipeline, and stand for Subsampling. They are used to subsample the original YUV 4:4:4 pixel ratio aspect to either 4:2:2 or 4:2:0. Add sub420 and sub422 to the reg offsets struct. This will allow different products to have a different reg offset for these particular modules. Signed-off-by:

The CBC submodule is a part of the atmel-isc pipeline, and stands for Contrast Brightness Control. It is used to apply gains and offsets to the luma (Y) and chroma (U, V) components of the YUV elements. Add cbc to the reg offsets struct. This will allow different products to have a different reg offset for this particular module. Signed-off-by:

The CBC submodule is a part of the atmel-isc pipeline, and stands for Contrast Brightness Control. It is used to apply gains and offsets to the luma (Y) and chroma (U, V) components of the YUV elements. The CBC submodule should be initialized in the product specific driver as it's product specific. Other products can implement it differently [hverkuil: made isc_sama5d2_config_cbc static] Signed-off-by:

Create a struct that holds register offsets that are product specific. Add initially the CSC register. This allows each product that contains a variant of the ISC to add their own register offset. Signed-off-by:

The CSC submodule is a part of the atmel-isc pipeline, and stands for Color Space Conversion. It is used to apply a matrix transformation to RGB pixels to convert them to the YUV components. The CSC submodule should be initialized in the product specific driver as it's product specific. Other products can implement it differently.

When calling the subdev, certain subdev drivers will overwrite the frame size and adding sizes which are beyond the ISC's capabilities. Thus we need to ensure the frame size is cropped to the maximum caps. Signed-off-by:

The driver name constant must defined based on product driver, thus moving the constant directly where it's required. This will allow each ISC based product to define it's own name. Signed-off-by:

Use the new vb2_queue_change_type() function in .vidioc_reqbufs and .vidioc_create_bufs instead of changing the queue type manually in vidioc_s_fmt_vbi_cap() and vidioc_s_fmt_sliced_vbi_cap(). This allows for a more consistent behavior, as .vidioc_reqbufs and .vidioc_create_bufs are when the queue will become "busy". Signed-off-by:

Vivid tracks the VBI capture mode in vivid_dev->stream_sliced_vbi_cap field. We can just look at the buffer type instead, and drop the field. Signed-off-by:

Tomi Valkeinen authored
On some platforms a video device can capture either video data or metadata. The driver can implement vidioc functions for both video and metadata, and use a single vb2_queue for the buffers. However, vb2_queue requires choosing a single buffer type, which conflicts with the idea of capturing either video or metadata. The buffer type of vb2_queue can be changed, but it's not obvious how this should be done in the drivers. To help this, add a new helper function vb2_queue_change_type() which ensures the correct checks and documents how it can be used. Signed-off-by:

There are several comments on this driver using those chars: - U+2013 ('–'): EN DASH - U+2018 ('‘'): LEFT SINGLE QUOTATION MARK - U+2019 ('’'): RIGHT SINGLE QUOTATION MARK They probably came from cut-and-pasting some texts found elsewhere. While there's nothing wrong on having those on comments in C, it is better to use ASCII chars for those specific cases, as the current variant doesn't really add any value. Signed-off-by: -

While there's nothing wrong with EN DASH on C code, this probably came from some cut-and paste from an ITU-T table. It sounds better to just an HYPHEN here. Reviewed-by:

The conversion tools used during DocBook/LaTeX/html/Markdown->ReST conversion and some cut-and-pasted text contain some characters that aren't easily reachable on standard keyboards and/or could cause troubles when parsed by the documentation build system.

The direction of the pipe argument must match the request-type direction bit or control requests may fail depending on the host-controller-driver implementation. Control transfers without a data stage are treated as OUT requests by the USB stack and should be using usb_sndctrlpipe(). Failing to do so will now trigger a warning. Fix the zero-length i2c-read request used for type detection by attempting to read a single byte instead.
