+ *
+ * The 1024-bin histogram module collects image-global but zone-weighted
+ * intensity distributions of pixels in fixed-width bins. The modules can be
+ * configured into different "plane modes" which affect the contents of the
+ * collected statistics. In plane mode 0, pixel intensities are taken regardless
+ * of colour plane into a single 1024-bin histogram with a bin width of 4. In
+ * plane mode 1, four 256-bin histograms with a bin width of 16 are collected -
+ * one for each CFA colour plane. In plane modes 4, 5, 6 and 7 two 512-bin
+ * histograms with a bin width of 8 are collected - in each mode one of the
+ * colour planes is collected into the first histogram and all the others are
+ * combined into the second. The histograms are stored consecutively in the bins
+ * array.
+ *
+ * The 16-bit pixel counts are stored as a 4-bit exponent in the most
+ * significant bits followed by a 12-bit mantissa. Conversion to a usable
+ * format can be done according to the following pseudo-code::
+ *
+ * if (e == 0) {
+ * bin = m * 2;
+ * } else {
+ * bin = (m + 4096) * 2^e
+ * }
+ *
+ * where
+ * e is the exponent value in range 0..15
+ * m is the mantissa value in range 0..4095
+ *
+ * The pixels used in calculating the statistics can be masked using three
+ * methods:
+ *
+ * 1. Pixels can be skipped in X and Y directions independently.
+ * 2. Minimum/Maximum intensities can be configured
+ * 3. Zones can be differentially weighted, including 0 weighted to mask them
+ *
+ * The data for this histogram can be collected from different tap points in the
+ * ISP depending on configuration - after the white balance or digital gain
+ * blocks, or immediately after the input crossbar.

+ * struct mali_c55_params_block_header - Mali-C55 parameter block header
+ *
+ * This structure represents the common part of all the ISP configuration

+ * driver inspects this common header to discern the block type and its size and
+ * properly handle the block content by casting it to the correct block-specific
+ * type.
+ *
+ * The @type field is one of the values enumerated by
+ * :c:type:`mali_c55_param_block_type` and specifies how the data should be
+ * interpreted by the driver. The @size field specifies the size of the
+ * parameters block and is used by the driver for validation purposes. The
+ * @flags field holds a bitmask of per-block flags MALI_C55_PARAM_BLOCK_FL_*.
+ *
+ * If userspace wants to disable an ISP block the
+ * MALI_C55_PARAM_BLOCK_FL_DISABLED bit should be set in the @flags field. In
+ * that case userspace may optionally omit the remainder of the configuration
+ * block, which will in any case be ignored by the driver. If a new

+ * populate the ISP block and omit setting the MALI_C55_PARAM_BLOCK_FL_DISABLED
+ * bit in the @flags field.

+/**
+ * struct mali_c55_params_aexp_hist - configuration for AEXP metering hists
+ *
+ * This struct allows users to configure the 1024-bin AEXP histograms. Broadly
+ * speaking the parameters allow you to mask particular regions of the image and
+ * to select different kinds of histogram.
+ *
+ * The skip_x, offset_x, skip_y and offset_y fields allow users to ignore or
+ * mask pixels in the frame by their position relative to the top left pixel.
+ * First, the skip_y, offset_x and offset_y fields define which of the pixels
+ * within each 2x2 region will be counted in the statistics.
+ *
+ * If skip_y == 0 then two pixels from each covered region will be counted. If
+ * both offset_x and offset_y are zero, then the two left-most pixels in each
+ * 2x2 pixel region will be counted. Setting offset_x = 1 will discount the top
+ * left pixel and count the top right pixel. Setting offset_y = 1 will discount
+ * the bottom left pixel and count the bottom right pixel.
+ *
+ * If skip_y != 0 then only a single pixel from each region covered by the
+ * pattern will be counted. In this case offset_x controls whether the pixel
+ * that's counted is in the left (if offset_x == 0) or right (if offset_x == 1)
+ * column and offset_y controls whether the pixel that's counted is in the top
+ * (if offset_y == 0) or bottom (if offset_y == 1) row.
+ *
+ * The skip_x and skip_y fields control how the 2x2 pixel region is repeated
+ * across the image data. The first instance of the region is always in the top
+ * left of the image data. The skip_x field controls how many pixels are ignored
+ * in the x direction before the pixel masking region is repeated. The skip_y
+ * field controls how many pixels are ignored in the y direction before the
+ * pixel masking region is repeated.
+ *
+ * These fields can be used to reduce the number of pixels counted for the
+ * statistics, but it's important to be careful to configure them correctly.
+ * Some combinations of values will result in colour components from the input
+ * data being ignored entirely, for example in the following configuration:
+ *
+ * skip_x = 0
+ * offset_x = 0
+ * skip_y = 0
+ * offset_y = 0
+ *
+ * Only the R and Gb components of RGGB data that was input would be collected.
+ * Similarly in the following configuration:
+ *
+ * skip_x = 0
+ * offset_x = 0
+ * skip_y = 1
+ * offset_y = 1
+ *
+ * Only the Gb component of RGGB data that was input would be collected. To
+ * correct things such that all 4 colour components were included it would be
+ * necessary to set the skip_x and skip_y fields in a way that resulted in all

+ * This struct contains the configuration parameters of the Mali-C55 ISP

+ * configure.
+ *
+ * The parameters buffer is versioned by the @version field to allow modifying

+ *
+ * For each ISP block that userspace wants to configure, a block-specific
+ * structure is appended to the @data buffer, one after the other without gaps
+ * in between nor overlaps. Userspace shall populate the @total_size field with
+ * the effective size, in bytes, of the @data buffer.

+ * When userspace simply wants to disable an ISP block the

+ *
+ * This struct contains the configuration parameters of the RkISP1 ISP
+ * algorithms, serialized by userspace into a data buffer. Each configuration
+ * parameter block is represented by a block-specific structure which contains a
+ * :c:type:`rkisp1_ext_params_block_header` entry as first member. Userspace
+ * populates the @data buffer with configuration parameters for the blocks that
+ * it intends to configure. As a consequence, the data buffer effective size
+ * changes according to the number of ISP blocks that userspace intends to
+ * configure and is set by userspace in the @data_size field.
+ *
+ * The parameters buffer is versioned by the @version field to allow modifying
+ * and extending its definition. Userspace shall populate the @version field to
+ * inform the driver about the version it intends to use. The driver will parse
+ * and handle the @data buffer according to the data layout specific to the
+ * indicated version and return an error if the desired version is not
+ * supported.
+ *
+ * Currently the single RKISP1_EXT_PARAM_BUFFER_V1 version is supported.
+ * When a new format version will be added, a mechanism for userspace to query
+ * the supported format versions will be implemented in the form of a read-only
+ * V4L2 control. If such control is not available, userspace should assume only
+ * RKISP1_EXT_PARAM_BUFFER_V1 is supported by the driver.
+ *
+ * For each ISP block that userspace wants to configure, a block-specific
+ * structure is appended to the @data buffer, one after the other without gaps
+ * in between nor overlaps. Userspace shall populate the @data_size field with
+ * the effective size, in bytes, of the @data buffer.
+ *
+ * The expected memory layout of the parameters buffer is::
