/**
* 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_bls_config * bls =
* ( struct rkisp1_ext_params_bls_config * ) block ;
*
* bls - > header . type = RKISP1_EXT_PARAMS_BLOCK_ID_BLS ;
* bls - > header . flags = RKISP1_EXT_PARAMS_FL_BLOCK_ENABLE ;
* bls - > header . size = sizeof ( * bls ) ;
*
* bls - > config . enable_auto = 0 ;
* bls - > config . fixed_val . r = blackLevelRed_ ;
* bls - > config . fixed_val . gr = blackLevelGreenR_ ;
* bls - > config . fixed_val . gb = blackLevelGreenB_ ;
* bls - > config . fixed_val . b = blackLevelBlue_ ;
* }
*
* @ type : The parameters block type , see
* : c : type : ` rkisp1_ext_params_block_type `
* @ flags : A bitmask of block flags
* @ size : Size ( in bytes ) of the parameters block , including this header

*
* 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 .
*
* The read - only V4L2 control ` ` RKISP1_CID_SUPPORTED_PARAMS_BLOCKS ` ` can be used
* to query the blocks supported by the device . It contains a bitmask where each
* bit represents the availability of the corresponding entry from the
* : c : type : ` rkisp1_ext_params_block_type ` enum . The current and default values
* of the control represents the blocks supported by the device instance , while
* the maximum value represents the blocks supported by the kernel driver ,
* independently of the device instance .
*
* 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 .
