The RLP submodule is a part of the atmel-isc pipeline, and stands for Rounding,Limiting and Packaging. It used to extract specific data from the ISC pipeline. For example if we want to output greyscale 8 bit, we would use limiting to 8 bits, and packaging to Luma component only. Create a product specific callback for initializing the RLP submodule of the pipeline [hverkuil: made isc_sama5d2_config_rlp static] Signed-off-by:

The GAM submodule is a part of the atmel-isc pipeline, and stands for Gamma Correction. It is used to apply the gamma curve to the incoming pixels. Create a product specific callback for initializing the GAM submodule of the pipeline. For sama5d2 product, there is no special configuration at this moment, thus this function is a noop.

The DPC submodule is a part of the atmel-isc pipeline, and stands for Defective Pixel Correction. Its purpose is to detect defective pixels and correct them if possible with the help of adjacent pixels. Create a product specific callback for initializing the DPC submodule of the pipeline. For sama5d2 product, this module does not exist, thus this function is a noop. [hverkuil: made isc_sama5d2_config_dpc static] Signed-off-by:

The CC submodule is a part of the atmel-isc pipeline, and stands for Color Correction. It is used to apply gains and offsets to the chroma (U, V) components of the YUV elements. Implement the CC submodule initialization, as a product specific function, which currently configures the neutral point in color correction.

Newer ISC pipelines have the additional modules of Defective Pixel Correction -> DPC itself, Defective Pixel Correction -> Green Disparity Correction (DPC_GDC) Defective Pixel Correction -> Black Level Correction (DPC_BLC) Vertical and Horizontal Scaler -> VHXS Some products have this full pipeline (sama7g5), other products do not (sama5d2) Add the modules to the isc base, and also extend the register range to include the modules.

The DMA submodule is a part of the atmel-isc pipeline, and stands for Direct Memory Access. It acts like a master on the AXI bus of the SoC, and can directly write the RAM area with the pixel data from the ISC internal sram. Add dma to the reg offsets struct. This will allow different products to have a different reg offset for this particular module. Signed-off-by:

The HIS submodule is a part of the atmel-isc pipeline, and stands for Histogram. This module performs a color histogram that can be read and used by the main processor. Add his to the reg offsets struct. This will allow different products to have a different reg offset for this particular module. Signed-off-by:

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:

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: -

Instead of using U+2013 ('–'): EN DASH, let's just use an hyphen there, as this was probably introduced by some cut-and-paste from some other place. 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:
