2013-12-18[media] v4l: atmel-isi: remove SOF wait in start_streaming()Josh Wu1-46/+1
when a userspace applications calls the VIDIOC_STREAMON ioctl. The V4L2 core calls the soc_camera_streamon function, which is responsible for starting the video stream. It does so by first starting the atmel-isi host by a call to the vb2_streamon function, and then starting the sensor by a call to the video.s_stream sensor subdev operation. That means we wait for a SOF in start_streaming() before call sensor's s_stream(). It is possible no VSYNC interrupt arrive as the sensor hasn't been started yet. To avoid such case, this patch remove the code to wait for the VSYNC interrupt. And such code is not necessary.

2013-12-18[media] omap3isp: Modify clocks registration to avoid circular referencesSylwester Nawrocki2-6/+17
The clock core code is going to be modified so clk_get() takes reference on the clock provider module. Until the potential circular reference issue is properly addressed, we pass NULL as the first argument to clk_register(), in order to disallow sub-devices taking a reference on the ISP module back trough clk_get(). This should prevent locking the modules in memory.

As the depth value of the format description entry is expressed in bits then the bytesperline value needs to be divided, not multiplied, by that value to get the number of bytes required to store single line of image samples.

2013-12-10[media] v4l: ti-vpe: make sure VPDMA line stride constraints are metArchit Taneja3-16/+46
When VPDMA fetches or writes to an image buffer, the line stride must be a multiple of 16 bytes. If it isn't, VPDMA HW will write/fetch until the next 16 byte boundry. This causes VPE to work incorrectly for source or destination widths which don't satisfy the above alignment requirement. In order to prevent this, we now make sure that when we set pix format for the input and output buffers, the VPE source and destination image line strides are 16 byte aligned. Also, the motion vector buffers for the de-interlacer are allocated in such a way that it ensures the same alignment.

2013-12-04[media] v4l: omap3isp: Don't check for missing get_fmt op on remote subdevLaurent Pinchart1-5/+2
The remote subdev of any video node in the OMAP3 ISP is an internal subdev that is guaranteed to implement get_fmt. Don't check the return value for -ENOIOCTLCMD, as this can't happen. While at it, move non-critical code out of the mutex-protected section.

2013-12-04omap3isp: Modify clocks registration to avoid circular referencesSylwester Nawrocki2-6/+17
The clock core code is going to be modified so clk_get() takes reference on the clock provider module. Until the potential circular reference issue is properly addressed, we pass NULL as the first argument to clk_register(), in order to disallow sub-devices taking a reference on the ISP module back trough clk_get(). This should prevent locking the modules in memory.
