As the members of the structure are part of the userspace API, the structure layout is immutable and cannot be extended further. Introducing new parameters or modifying the existing ones would change the buffer layout and cause breakages in existing applications. The allow for future extensions to the ISP parameters, introduce a new extensible parameters format, with a new format 4CC. Document usage of the new format in the rkisp1 admin guide.

As the parameters buffer is mapped in the userspace process memory, applications have access to the buffer content after the buffer has been queued. To prevent userspace from modifying the contents of the parameters buffer after it has been queued to the video device, add to 'struct rkisp1_params_buffer' a scratch buffer where to copy the parameters. Allocate the scratch buffer in the vb2 buf_init() operation and copy the buffer content in the buf_prepare() operation. Free the scratch buffer in the newly introduced buf_cleanup() operation handler. Modify the ISP configuration function to access the ISP configuration from the cached copy of the parameters buffer instead of using the userspace-mapped one.

The usage of the "fixed" format is assumed when allocating memory for the scratch buffers and when initializing the vb2 queue. In order to prepare to support the "extensible" format beside the existing "fixed" one, add support in the driver for both formats by caching a pointer to the active one in the driver structure and use it in the vb2 queue operations and subdev pad operations implementations. Do not yet allow userspace to select between the two formats as the support for the "extensible" format parsing will be introduced in a later patch in the series. While at it, document the un-documented ycbcr_encoding field of struct rkisp1_params_ops.

Create a list of handlers for each ISP block that wraps the existing configuration functions and handles the ISP block enablement. Parse the configuration parameters buffer in rkisp1_ext_params_config and filter the enable blocks by group, to allow setting the 'other' groups separately from the 'lsc' group to support the pre/post-configure operations. Implement parameter buffer validation for the extensible format at .buf_prepare() time.
