2022-08-30media: ti: cal: combine wdma irq handlingTomi Valkeinen1-34/+25
Instead of handling the WDMA START and END interrupts separately, we need to handle both at the same time to better manage the inherent race conditions related to CAL interrupts. Change the code so that we have a single function, cal_irq_handle_wdma(), which gets two booleans, start and end, as parameters, which allows us to manage the race conditions in the following patch.

2022-08-30media: ti: cal: use CSI-2 frame number for seq numberTomi Valkeinen3-3/+62
The userspace needs a way to match received metadata buffers to pixel data buffers. The obvious way to do this is to use the CSI-2 frame number, as both the metadata and the pixel data have the same frame number as they come from the same frame. However, we don't have means to convey the frame number to userspace. We do have the 'sequence' field, which with a few tricks can be used for this purpose. To achieve this, track the frame number for each virtual channel and increase the sequence for each virtual channel by frame-number - previous-frame-number, also taking into account the eventual wrap of the CSI-2 frame number. If the CSI-2 peripheral does not support frame numbers, CAL increases the frame number register by one each frame. This way we get a monotonically increasing sequence number which is common to all streams using the same virtual channel.

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.
