Age	Commit message (Collapse)	Author
2018-12-11	utils: ipu3: process: Configure formats on ImgU subdev pads	Laurent Pinchart
	Set format and selection rectangles on the ImgU subdev as required by the driver. Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com>
2018-12-11	utils: ipu3: process: Fix typo in output files path	Laurent Pinchart
	A typo in the output files path causes the script to attempt to write all captured frames to /. Fix it. Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com>
2018-12-11	utils: ipu3: Abort when sensor or media device isn't found	Laurent Pinchart
	Calling exit from a function only exits from the function, it doesn't abort the whole script. Propagate the errors to stop operation when the sensor or media device can't be found. Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com>
2018-12-02	utils: ipu3: Add test process script	Laurent Pinchart
	The script processes raw frames through the Intel IPU3 IMGU. Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com>
2018-11-29	utils: ipu3: Add test capture script	Laurent Pinchart
	The script captures raw frames from cameras based on the Intel IPU3. It takes the sensor name as an argument and isn't meant to depend on a particular platform. Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Acked-by: Kieran Bingham <kieran.bingham@ideasonboard.com>
2018-11-20	utils: ipu3: Add IPU3 raw capture unpack utility	Laurent Pinchart
	The IPU3 captures Bayer data in a 25-pixels-in-32-bytes packed format, which no standard tool can process. Add a quick implementation of data unpacking to turn raw binary files into 16 bits per pixel unpacked Bayer data. Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Reviewed-by: Jacopo Mondi <jacopo@jmondi.org>
