  1105.  * The @flags field is a bitmask of per-block flags RKISP1_EXT_PARAMS_FL_*.
  1106.  *

  1505.  * populates the @data buffer with configuration parameters for the blocks that

  1507.  * changes according to the number of ISP blocks that userspace intends to
  1508.  * configure and is set by userspace in the @data_size field.
  1509.  *
  1510.  * The parameters buffer is versioned by the @version field to allow modifying
  1511.  * and extending its definition. Userspace shall populate the @version field to
  1512.  * inform the driver about the version it intends to use. The driver will parse
  1513.  * and handle the @data buffer according to the data layout specific to the
  1514.  * indicated version and return an error if the desired version is not
  1515.  * supported.
  1516.  *
  1517.  * Currently the single RKISP1_EXT_PARAM_BUFFER_V1 version is supported.
  1518.  * When a new format version will be added, a mechanism for userspace to query
  1519.  * the supported format versions will be implemented in the form of a read-only
  1520.  * V4L2 control. If such control is not available, userspace should assume only
  1521.  * RKISP1_EXT_PARAM_BUFFER_V1 is supported by the driver.
  1522.  *
  1523.  * For each ISP block that userspace wants to configure, a block-specific
  1524.  * structure is appended to the @data buffer, one after the other without gaps
  1525.  * in between nor overlaps. Userspace shall populate the @data_size field with
  1526.  * the effective size, in bytes, of the @data buffer.
  1527.  *
