SPDX-License-Identifier: GPL-2.0 -+ -+BCM2835 ISP Driver -+================== -+ -+Introduction -+------------ -+ -+The BCM2835 Image Sensor Pipeline (ISP) is a fixed function hardware pipeline -+for performing image processing operations. Images are fed to the input -+of the ISP through memory frame buffers. These images may be in various YUV, -+RGB, or Bayer formats. A typical use case would have Bayer images obtained from -+an image sensor by the BCM2835 Unicam peripheral, written to a memory -+frame buffer, and finally fed into the input of the ISP. Two concurrent output -+images may be generated in YUV or RGB format at different resolutions. -+Statistics output is also generated for Bayer input images. -+ -+The bcm2835-isp driver exposes the following media pads as V4L2 device nodes: -+ -+.. tabularcolumns:: |l|l|l|l| -+ -+.. cssclass: longtable -+ -+.. flat-table:: -+ -+ * - *Pad* -+ - *Direction* -+ - *Purpose* -+ - *Formats* -+ -+ * - "bcm2835-isp0-output0" -+ - sink -+ - Accepts Bayer, RGB or YUV format frame buffers as input to the ISP HW -+ pipeline. -+ - :ref:`RAW8 <V4L2-PIX-FMT-SRGGB8>`, -+ :ref:`RAW10P <V4L2-PIX-FMT-SRGGB10P>`, -+ :ref:`RAW12P <V4L2-PIX-FMT-SRGGB12P>`, -+ :ref:`RAW14P <V4L2-PIX-FMT-SRGGB14P>`, -+ :ref:`RAW16 <V4L2-PIX-FMT-SRGGB16>`, -+ :ref:`RGB24/BGR24 <V4L2-PIX-FMT-RGB24>`, -+ :ref:`YUYV <V4L2-PIX-FMT-YUYV>`, -+ :ref:`YVYU <V4L2-PIX-FMT-YVYU>`, -+ :ref:`UYVY <V4L2-PIX-FMT-UYVY>`, -+ :ref:`VYUY <V4L2-PIX-FMT-VYUY>`, -+ :ref:`YUV420/YVU420 <V4L2-PIX-FMT-YUV420>` -+ -+ * - "bcm2835-isp0-capture1" -+ - source -+ - High resolution YUV or RGB processed output from the ISP. -+ - :ref:`RGB565 <V4L2-PIX-FMT-RGB565>`, -+ :ref:`RGB24/BGR24 <V4L2-PIX-FMT-RGB24>`, -+ :ref:`ABGR32 <V4L2-PIX-FMT-ABGR32>`, -+ :ref:`YUYV <V4L2-PIX-FMT-YUYV>`, -+ :ref:`YVYU <V4L2-PIX-FMT-YVYU>`, -+ :ref:`UYVY <V4L2-PIX-FMT-UYVY>`, -+ :ref:`VYUY <V4L2-PIX-FMT-VYUY>`. -+ :ref:`YUV420/YVU420 <V4L2-PIX-FMT-YUV420>`, -+ :ref:`NV12/NV21 <V4L2-PIX-FMT-NV12>`, -+ -+ * - "bcm2835-isp0-capture2" -+ - source -+ - Low resolution YUV processed output from the ISP.
