media: xc2028: rename the driver from tuner-xc2028

This is the only tuner driver that has "tuner-" on its name. Rename it, in order to match all the other tuner drivers. Signed-off-by: Mauro Carvalho Chehab

media: imx: Rename imx7-mipi-csis.c to imx-mipi-csis.c

2022-02-23T07:53:07+00:00

Rename the imx7-mipi-csis.c driver to remove the reference to i.MX7. The driver is for an IP core found on i.MX7 and i.MX8 SoC, so do not specify a SoC version number in the driver name. Remove the references to the i.MX7 SoC in the driver symbols and expand the driver's header with more information about the IP core the driver controls. Also rename the associated bindings documentation. Signed-off-by: Jacopo Mondi Reviewed-by: Laurent Pinchart Acked-by: Rui Miguel Silva Acked-by: Sakari Ailus Signed-off-by: Hans Verkuil

media: vimc: Add support for contiguous DMA buffers

2022-02-16T11:47:02+00:00

The vimc driver is used for testing purpose, and some test use cases involve sharing buffers with a consumer device. Consumers often require DMA contiguous memory, which vimc doesn't currently support. This leads in the best case to usage of bounce buffers, which is very slow, and in the worst case in a complete failure. Add support for the dma-contig allocator in vimc to support those use cases properly. The allocator is selected through a new "allocator" module parameter, which defaults to vmalloc.

media: vimc: Enable set resolution at the scaler src pad

2021-09-30T08:07:59+00:00

Modify the scaler subdevice to accept setting the resolution of the source pad (previously the source resolution would always be 3 times the sink for both dimensions). Now any resolution can be set at src (even smaller ones) and the sink video will be scaled to match it. Test example: With the vimc module up (using the default vimc topology) media-ctl -d platform:vimc -V '"Sensor A":0[fmt:SBGGR8_1X8/640x480]' media-ctl -d platform:vimc -V '"Debayer A":0[fmt:SBGGR8_1X8/640x480]' media-ctl -d platform:vimc -V '"Scaler":0[fmt:RGB888_1X24/640x480]' media-ctl -d platform:vimc -V '"Scaler":0[crop:(100,50)/400x150]' media-ctl -d platform:vimc -V '"Scaler":1[fmt:RGB888_1X24/300x700]' v4l2-ctl -z platform:vimc -d "RGB/YUV Capture" -v width=300,height=700 v4l2-ctl -z platform:vimc -d "Raw Capture 0" -v pixelformat=BA81 v4l2-ctl --stream-mmap --stream-count=10 -z platform:vimc -d "RGB/YUV Capture" \ --stream-to=test.raw The result will be a cropped stream that can be checked with the command ffplay -loglevel warning -v info -f rawvideo -pixel_format rgb24 \ -video_size "300x700" test.raw Co-developed-by: Gabriela Bittencourt Signed-off-by: Gabriela Bittencourt Co-developed-by: Gabriel Francisco Mandaji Signed-off-by: Gabriel Francisco Mandaji Signed-off-by: Pedro Terra Reviewed-by: Laurent Pinchart Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab
