Setting the H and V flip controls at webcam connection time prevents the webcam to work correctly. This patch checks if the webcam is streaming before setting the flips. It does not set the flips (nor other controls) at webcam start time. Tested-by:

Some sensors can have more than one pad (case of S5C73M3). In such cases FIMC assumes the last pad of the sensor is the source pad. Signed-off-by:

Add second source media pad for the FIFO data output to FIMC-IS and implement subdev s_stream op for configurations where FIMC-LITE is used as a glue logic between FIMC-IS and MIPI-CSIS or an image sensor. The second source media pad will be linked to the FIMC-LITE video node. For proper configuration the attached image sensor/video encoder properties are needed, like video bus type, signal polarities, etc. For this purpose there is a small routine added that walks the pipeline and returns the sensor subdev.

Setting FIMC_REG_CITRGFMT_FLIP_X_MIRROR bit causes X-axis image flip (vertical flip) and thus it corresponds to V4L2_CID_VFLIP. Likewise, setting FIMC_REG_CITRGFMT_FLIP_Y_MIRROR bit causes Y-axis image flip (horizontal flip) and thus it corresponds to V4L2_CID_HFLIP. Currently the driver does X-axis flip when V4L2_CID_HFLIP is set and Y-axis flip for V4L2_CID_VFLIP. Fix this incorrect assignment by setting proper FIMC_REG_CITRGFMT register bits for ctx->hflip and ctx->vflip. Reported-by:

Define video buffer flags for different timestamp types. Everything up to now have used either realtime clock or monotonic clock, without a way to tell which clock the timestamp was taken from. Also document that the clock source of the timestamp in the timestamp field depends on buffer flags.

Explicit checks for the JPEG pixel format in soc_mbus_bytes_per_line() and soc_mbus_image_size() are superfluous, because also without them these functions will perform correctly. The former will return 0 based on packing == SOC_MBUS_PACKING_VARIABLE and the latter will simply multiply the user-provided line length by the image height to obtain a frame buffer size estimate. The original version of the "media: soc_camera: don't clear pix->sizeimage in JPEG mode" patch was correct and my amendment, adding these two checks was superfluous. Signed-off-by:

Video Engine Unit (VEU) is an IP block, found in multiple SuperH and ARM- based sh-mobile and r-mobile SoCs, capable of processing video data. It can perform colour-space conversion, scaling and several filtering transformations. This patch adds an initial implementation of a mem2mem V4L2 driver for VEU. So far only conversion from NV12 to RGB565 is supported. Further functionality shall be added in the future. This driver is based on a VEU vidix driver by Magnus Damm. Signed-off-by:
