* struct rkisp1_ext_params_block_header - RkISP1 extensible parameters block
* header
*
* This structure represents the common part of all the ISP configuration
* blocks. Each parameters block shall embed an instance of this structure type
* as its first member, followed by the block-specific configuration data. The
* 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:`rkisp1_ext_params_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 is a bitmask of per-block flags RKISP1_EXT_PARAMS_FL_*.
*
* When userspace wants to configure and enable an ISP block it shall fully
* populate the block configuration and set the
* RKISP1_EXT_PARAMS_FL_BLOCK_ENABLE bit in the @flags field.
*
* When userspace simply wants to disable an ISP block the
* RKISP1_EXT_PARAMS_FL_BLOCK_DISABLE bit should be set in @flags field. The
* driver ignores the rest of the block configuration structure in this case.
*
* If a new configuration of an ISP block has to be applied userspace shall
* fully populate the ISP block configuration and omit setting the
* RKISP1_EXT_PARAMS_FL_BLOCK_ENABLE and RKISP1_EXT_PARAMS_FL_BLOCK_DISABLE bits
* in the @flags field.
*
* Setting both the RKISP1_EXT_PARAMS_FL_BLOCK_ENABLE and
* RKISP1_EXT_PARAMS_FL_BLOCK_DISABLE bits in the @flags field is not allowed
* and not accepted by the driver.
*
* Userspace is responsible for correctly populating the parameters block header
* fields (@type, @flags and @size) and the block-specific parameters.
*
* For example:
*
* .. code-block:: c
*
* void populate_bls(struct rkisp1_ext_params_block_header *block) {

/**
* struct rkisp1_ext_params_cfg - RkISP1 extensible parameters configuration
*
* 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::
