The isp->inputs[] array has isp->input_cnt elements which have been initialized so this > should be >=. This bug is harmless. The check against ATOM_ISP_MAX_INPUTS prevents us from reading beyond the end of the array. The uninitialized elements are zeroed out so we will end up returning -EINVAL a few lines later because the .camera pointer is NULL.

If the mdp_* nodes are under an mdp sub-node, their corresponding platform device does not automatically get its iommu assigned properly. Fix this by moving the mdp component nodes up a level such that they are siblings of mdp and all other SoC subsystems. This also simplifies the device tree. Although it fixes iommu assignment issue, it also break compatibility with old device tree. So, the patch in driver is needed to iterate over sibling mdp device nodes, not child ones, to keep driver work properly.

The current driver has a handful of hard-coded assumptions based on its primary use for capture of video signals. Cleanup those assumptions, and also query the subdev for format information and use that if available. Tested with 10-bit raw bayer input (SGRBG10) using the aptina,mt9v032 sensor, and also tested that composite video input still works from ti,tvp514x decoder. Both tests done on the da850-evm board with the add-on UI board. NOTE: Will need further testing for other sensors with different bus formats.

Kevin Hilman authored
Capture driver silently overrides pixel format with a hack (according to the comments) to pass v4l2 compliance tests. This isn't needed for normal functionality, and works for composite video and raw camera capture without. In addition, the hack assumes that it only supports raw capture with a single format (SBGGR8) which isn't true. VPIF can also capture 10- and 12-bit raw formats as well. Forthcoming patches will enable VPIF input with raw-camera support and has been tested with 10-bit format from the aptina,mt9v032 sensor. Any compliance failures should be fixed with a real fix.

Anton Blanchard authored
The ir-spi driver has 2 issues which prevents it from working with lirc: 1. The ir-spi driver uses 16 bits of SPI data to create one cycle of the waveform. As such our SPI clock needs to be 16x faster than the carrier frequency. The driver is inconsistent in how it currently handles this. It initializes it to the carrier frequency: But the commit message has some example code which initialises it to 16x the carrier frequency: val = 608000; ret = ioctl(fd, LIRC_SET_SEND_CARRIER, &val); To maintain compatibility with lirc, always do the frequency adjustment in the driver. 2. lirc presents pulses in microseconds, but the ir-spi driver treats them as cycles of the carrier. Similar to other lirc drivers, do the conversion with DIV_ROUND_CLOSEST().

interrupts is listed as an optional property in the DT binding, but in reality the driver didn't work without it.

For both BT.656 and BT.1120 video, the pixel format used by VPIF is Y/CbCr 4:2:2 in semi-planar format (Luma in one plane and Chroma in another). This corresponds to NV16 pixel format. This is documented in section 36.2.3 of OMAP-L138 Technical Reference Manual, SPRUH77A. The VPIF driver incorrectly sets the default format to V4L2_PIX_FMT_YUV422P. Fix it.
