+ * DOC: Generic Radix Page Table
+ *
+ * Generic Radix Page Table is a set of functions and helpers to efficiently
+ * parse radix style page tables typically seen in HW implementations. The
+ * interface is built to deliver similar code generation as the mm's pte/pmd/etc
+ * system by fully inlining the exact code required to handle each table level.
+ *
+ * Like the mm subsystem each format contributes its parsing implementation
+ * under common names and the common code implements the required algorithms.
+ *
+ * The system is divided into three logical levels:
+ *
+ * - The page table format and its manipulation functions
+ * - Generic helpers to give a consistent API regardless of underlying format
+ * - An algorithm implementation (e.g. IOMMU/DRM/KVM/MM)
+ *
+ * Multiple implementations are supported. The intention is to have the generic
+ * format code be re-usable for whatever specialized implementation is required.
+ * The generic code is solely about the format of the radix tree; it does not
+ * include memory allocation or higher level decisions that are left for the
+ * implementation.
+ *
+ * The generic framework supports a superset of functions across many HW
+ * implementations:
+ *
+ * - Entries comprised of contiguous blocks of IO PTEs for larger page sizes
+ * - Multi-level tables, up to 6 levels. Runtime selected top level
+ * - Runtime variable table level size (ARM's concatenated tables)
+ * - Expandable top level allowing dynamic sizing of table levels
+ * - Optional leaf entries at any level
+ * - 32-bit/64-bit virtual and output addresses, using every address bit
+ * - Dirty tracking
+ * - Sign extended addressing

+/**
+ * DOC: Live Update Orchestrator ABI
+ *
+ * This header defines the stable Application Binary Interface used by the
+ * Live Update Orchestrator to pass state from a pre-update kernel to a
+ * post-update kernel. The ABI is built upon the Kexec HandOver framework
+ * and uses a Flattened Device Tree to describe the preserved data.
+ *
+ * This interface is a contract. Any modification to the FDT structure, node
+ * properties, compatible strings, or the layout of the `__packed` serialization
+ * structures defined here constitutes a breaking change. Such changes require
+ * incrementing the version number in the relevant `_COMPATIBLE` string to
+ * prevent a new kernel from misinterpreting data from an old kernel.
+ *
+ * Changes are allowed provided the compatibility version is incremented;
+ * however, backward/forward compatibility is only guaranteed for kernels
+ * supporting the same ABI version.
+ *
+ * FDT Structure Overview:
+ * The entire LUO state is encapsulated within a single KHO entry named "LUO".
+ * This entry contains an FDT with the following layout:
+ *
+ * .. code-block:: none
+ *
+ * / {
+ * compatible = "luo-v1";
+ * liveupdate-number = <...>;
+ *
+ * luo-session {
+ * compatible = "luo-session-v1";
+ * luo-session-header = <phys_addr_of_session_header_ser>;
+ * };
+ * };
+ *
+ * Main LUO Node (/):
+ *
+ * - compatible: "luo-v1"
+ * Identifies the overall LUO ABI version.
+ * - liveupdate-number: u64
+ * A counter tracking the number of successful live updates performed.
+ *
+ * Session Node (luo-session):
+ * This node describes all preserved user-space sessions.
+ *
+ * - compatible: "luo-session-v1"
+ * Identifies the session ABI version.
+ * - luo-session-header: u64

+ * 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::
+ *

+ *
+ * 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_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
