media: v4l2-ctrls: drop 'elems' argument from control type ops.

2022-09-24T06:49:06Z

The type ops for equal, init and validate have an elems argument, but this can be taken from struct v4l2_ctrl: ctrl->elems for equal and init, and ctrl->new_elems for validate (since you are validating a new control value). So drop this argument and update all callers. Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab

media: dw100: Fix an error handling path in dw100_probe()

2022-08-30T05:35:47Z

After a successful call to media_device_init() it is safer to call media_device_cleanup(). Add the missing call in the error handling path of the probe, as already done in the remove function.

media: fsl-viu: deprecate this driver

2022-08-29T14:44:54Z

Deprecate the fsl-viu driver. This driver does not use the vb2 framework for video streaming, instead it uses the old videobuf framework. We want to get rid of these old drivers, so deprecated it for future removal. Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab

media: dw100: Add i.MX8MP dw100 dewarper driver

2022-08-29T13:32:13Z

Add a V4L2 mem-to-mem driver for the Vivante DW100 Dewarp Processor IP core found on i.MX8MP SoC. The processor core applies a programmable geometrical transformation on input images to correct distorsion introduced by lenses. The transformation function is exposed as a grid map with 16x16 pixel macroblocks indexed using X, Y vertex coordinates. The dewarping map can be set from application through a dedicated v4l2 control. If not set or invalid, the driver computes an identity map prior to starting the processing engine. The driver supports scaling, cropping and pixel format conversion.

media: imx: imx-mipi-csis: Implement the .get_frame_desc() operation

2022-07-16T07:43:15Z

The CSIS is connected to its sink through an SoC-specific gasket that needs to be configured. Depending on the platform, the gasket configuration requires knowing the CSI-2 DT. To provide the needed information, implement the .get_frame_desc() operation. Signed-off-by: Laurent Pinchart Reviewed-by: Rui Miguel Silva Signed-off-by: Mauro Carvalho Chehab

media: imx: imx-mipi-csis: Add version register

2022-07-16T07:42:56Z

Register at offset 0x00 isn't documented, but the NXP BSP imx8-mipi-csi2-sam driver defines it as a version register. Tests on i.MX7D and i.MX8MP have confirmed this, with values matching the version of the IP core specified in the respective reference manuals. This commit doesn't make use of the version register at runtime as the compatible strings are enough to identify the IP core version. Nonetheless, capturing the information in register definitions that don't affect the code negatively is useful for future development.
