	Since meson v0.49.0, join_paths() is equivalent to '/' hence, drop and replace it with '/' short-hand in meson files. This commit does not introduce any functional changes.

2021-03-14	ipa: raspberrypi: Add support for imx327-based SE327M12 module	David Plowman
	This patch adds support for the Soho Enterprises SE327M12 module. The sensor is an imx327 which therefore uses the imx290 kernel driver and CamHelper. To use this module and camera tuning, place the following in the /boot/config.txt file: dtoverlay=imx290,clock-frequency=37125000 and then the existing imx290.json file must be over-written with se327m12.json Signed-off-by: David Plowman <david.plowman@raspberrypi.com> Reviewed-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com>
2021-03-09	ipa: raspberrypi: Add support for imx290/imx327 sensors	David Plowman
	imx290 and imx327 share the same kernel driver (imx290.c) and are therefore both recognised here as "imx290". We add the necessary CamHelper for these sensors, as well as a camera tuning file. The tuning was done with an Innomaker STARVIS IMX327LQR module. These have no IR cut filter so there is no proper colour tuning. However, you should obtain reasonable results for most modules using this sensor. Specific tunings for further modules can always be added subsequently. To use this sensor on the Raspberry Pi platform, please add dtoverlay=imx290,clock-frequency=74250000 into your /boot/config.txt file.

2021-01-20	ipa: raspberrypi: config: Update shutter speeds for imx219/477 and ov5647	Naushir Patuck
	Set the maximum shutter speed for the normal exposure profile to 66ms, allowing viewfinder framerates to go down to approx. 15fps. Set the maximum shutter speed for the sport exposure profile to 33ms, limiting the minimum framerate to approx. 30fps. Add a long exposure profile to allow shutter speeds of up to 120ms.

2020-12-01	src: ipa: raspberrypi: Fix initial AGC oscillation for imx219 sensor	David Plowman
	The exposure times in the exposure modes were causing AGC oscillations because the algorithm was demanding long unachievable exposure times but, without working sensor metadata, thought it was getting them when actually it was not. We fix it by making the exposure profile request only achievable exposure times, as we do for the ov5647 tuning.

	The names have to match for the setting to work. Use the libcamera terminology for consistency (even though it touches more files).

2020-07-03	ipa: raspberrypi: Enable focus measure without recompile	David Plowman
	Previously, output of the focus measure could not be enabled without recompiling (because of the RPI_LOGGING_ENABLE macro). This uses the libcamera logging mechanism instead, so can be enabled/disabled at runtime.

2020-06-25	ipa: rpi: Add "focus" algorithm	David Plowman
	Adds FocusStatus to the image metadata, containing contrast measurements across the image. Optionally also prints a contrast measure to the console, to aid in manual adjustment of the lens. Note that it is not an actual auto-focus algorithm that can drive a lens!
