1549 * This is the driver-specific implementation of
1550 * :c:type:`v4l2_isp_params_buffer`.
1551 *
1552 * Currently the single RKISP1_EXT_PARAM_BUFFER_V1 version is supported.
1553 * When a new format version will be added, a mechanism for userspace to query
1554 * the supported format versions will be implemented in the form of a read-only
1555 * V4L2 control. If such control is not available, userspace should assume only
1556 * RKISP1_EXT_PARAM_BUFFER_V1 is supported by the driver.
1557 *
1558 * The read-only V4L2 control ``RKISP1_CID_SUPPORTED_PARAMS_BLOCKS`` can be used
1559 * to query the blocks supported by the device. It contains a bitmask where each
1560 * bit represents the availability of the corresponding entry from the
1561 * :c:type:`rkisp1_ext_params_block_type` enum. The current and default values
1562 * of the control represents the blocks supported by the device instance, while
1563 * the maximum value represents the blocks supported by the kernel driver,
1564 * independently of the device instance.
1565 *
1566 * The expected memory layout of the parameters buffer is::
