From 9cacf4e42086abe57b3998a0d909b49b97a1a7a5 Mon Sep 17 00:00:00 2001 From: Laurent Pinchart Date: Mon, 1 Jul 2024 18:26:32 +0300 Subject: ipa: rkisp1: Add ISP parameters abstraction class Individual algorithms of the rkisp1 IPA module access their corresponding ISP parameters through the top-level structure rkisp1_params_cfg. This will not work anymore with the new parameters format. In order to ease the transition to the new format, abstract the ISP parameters in a new RkISP1Params class that offers the same interface regardless of the format.
