Extend the range of supported UVC devices by allowing video output devices matching the following structure: TT_STREAMING -> VC_PROCESSING_UNIT -> VC_EXTENSION_UNIT{0,n} -> OTT_* Video output devices are reported with the V4L2_CAP_VIDEO_OUTPUT capability flag and are subject to the same restrictions as video input devices.

Built-in iSight webcams have an interrupt endpoint but spit proprietary data that don't conform to the UVC status endpoint messages. Don't try to handle the interrupt endpoint for those cameras. Signed-off-by:

When the first bulk URB of a video payload contains an erroneous header, or when no V4L2 buffer is available, the whole payload must be dropped. Change the skip logic to drop all bulk URBs until the end of the payload instead of the first one only. Signed-off-by:

With the introduction of the format conversion support in soc-camera, we now also have to take care to pass the correct pixel format to the camera driver when calling its try_fmt() method. Signed-off-by:

This patch adds support for NV16 and NV61 pixel formats. These pixel formats use two planes; one for 8-bit Y values and one for interleaved 8-bit U and V values. NV16/NV61 formats are very similar to NV12/NV21 with the exception that NV16/NV61 are using the same number of lines for both planes. The difference between NV16 and NV61 is the U and V byte order. The fourcc values are extrapolated from the NV12/NV21 case. Signed-off-by:

Using PXA270's FIFO inactivity time-out register (CITOR) reduces FIFO overruns. The time-out is calculated in CICLK / LCDCLK ticks and has to be longer than one pixel time. For this we have to know the pixel clock frequency, which usually is provided by the camera. We use the struct soc_camera_sense to request PCLK frequency from the camera driver upon each data format change. Tested-by:

Add a struct soc_camera_sense, that can be used by camera host drivers to request additional information from a camera driver, for example, when changing data format. This struct can be extended in the future, its first use is to request the camera driver whether the pixel-clock frequency has changed. Tested-by:

As reported by Antonio Ospite <ospite@studenti.unina.it> two platforms with a mt9m111 camera require opposite pixel clock polarity, which means one of them inverts it. This patch adds support for inversion flags and switches all available camera drivers to using them. Signed-off-by:
