Subject: [PATCH v3 0/3] media: rkisp1: Add
 RKISP1_CID_SUPPORTED_PARAMS_BLOCKS ctrl and WDR support

Hi all,

This series adds RKISP1_CID_SUPPORTED_PARAMS_BLOCKS control to query the
parameters blocks that are supported by the current kernel on the
current hardware. This is required to be able to enable/disable the
corresponding algorithms in user space without relying solely on the
kernel version.

In addition to that it includes the WDR patch by Jai which is already in v5 and
was reviewed here:
https://lore.kernel.org/linux-media/20250521231355.GN12514@pendragon.ideasonboard.com/

Version 2 of this series drops the unnecessary initial cleanup patch.
Patch 1 was updated and has a local changelog. Patch 2 is unmodified.

Version 3 splits off the first commit again as it was considered worth
an own patch. Patch 2 was improved a bit based on review comments (see
local changelog).
