Use standard V4L2 control to get pixel clock rate from a sensor linked in the media controller pipeline. Then calculate clock rates on CSIPHY, CSID and VFE to use the lowest possible. If the currnet pixel clock rate of the sensor cannot be read then use the highest possible. This case covers also the CSID test generator usage. If VFE is already powered on by another pipeline, check that the current VFE clock rate is high enough for the new pipeline. If not return busy error code as VFE clock rate cannot be changed while VFE is running. Signed-off-by:

Todor Tomov authored
Use VFE PIX input interface and do format conversion in VFE. Supported input format is UYVY (single plane YUV 4:2:2) and its different sample order variations. Supported output formats are: - NV12/NV21 (two plane YUV 4:2:0) - NV16/NV61 (two plane YUV 4:2:2) Signed-off-by:

These files control the VFE module. The VFE has different input interfaces. The PIX input interface feeds the input data to an image processing pipeline. Three RDI input interfaces bypass the image processing pipeline. The VFE also contains the AXI bus interface which writes the output data to memory. RDI interfaces are supported in this version. PIX interface is not supported. Signed-off-by:

These formats are compressed 12-bit raw bayer formats with four different pixel orders. They are similar to 10-bit variants. The formats added by this patch are V4L2_PIX_FMT_SBGGR12P V4L2_PIX_FMT_SGBRG12P V4L2_PIX_FMT_SGRBG12P V4L2_PIX_FMT_SRGGB12P Signed-off-by:

The calculation of the left volume looks suspect, the value of 0x1f - ((val << 8) & 0x1f) is always 0x1f. The debug prior to the assignment of value[1] prints the left volume setting using the calculation 0x1f - (val >> 8) & 0x1f which looks correct to me. Fix the left volume by using the correct expression as used in the debug.

This change the alignment restriction for output type of buffers only, also set corect input resolution and fill bidirectional vb2 queue flag in order to map output type buffers read/write. The last is needed by encoder firmware to add padding at the bottom of output (input buffers). Signed-off-by:

Stanimir Varbanov authored
This change is intended to give to the v4l2 drivers a choice to change the default behavior of the v4l2-core DMA mapping direction from DMA_TO/FROM_DEVICE (depending on the buffer type CAPTURE or OUTPUT) to DMA_BIDIRECTIONAL during queue_init time. Initially the issue with DMA mapping direction has been found in Venus encoder driver where the hardware (firmware side) adds few lines padding on bottom of the image buffer, and the consequence is triggering of IOMMU protection faults. This will help supporting venus encoder (and probably other drivers in the future) which wants to map output type of buffers as read/write. Signed-off-by:

Implements g_/s_selection crop support by using DCMI crop hardware feature. User can first get the maximum supported resolution of the sensor by calling g_selection(V4L2_SEL_TGT_CROP_BOUNDS). Then user call to s_selection(V4L2_SEL_TGT_CROP) will reset sensor to its maximum resolution and crop request is saved for later usage in s_fmt(). Next call to s_fmt() will check if sensor can do frame size request with crop request. If sensor supports only discrete frame sizes, the frame size which is larger than user request is selected in order to be able to match the crop request. Then s_fmt() resolution user request is adjusted to match crop request resolution. Signed-off-by:
