-Subject: [PATCH] media: uapi: v4l2-core: Add ISP statistics output
- V4L2 fourcc type
-
-Add V4L2_META_FMT_BCM2835_ISP_STATS V4L2 format type.
-
-This new format will be used by the BCM2835 ISP device to return
-out ISP statistics for 3A.

-+Description
-+===========
-+
-+The BCM2835 ISP hardware calculate image statistics for an input Bayer frame.
-+These statistics are obtained from the "bcm2835-isp0-capture3" device node
-+using the :c:type:`v4l2_meta_format` interface. They are formatted as described
-+by the :c:type:`bcm2835_isp_stats` structure below.
