From b6fa52fc5bdc928daee0fd2fc33208bfdf0477d1 Mon Sep 17 00:00:00 2001 From: Jean-Michel Hautbois Date: Thu, 18 Nov 2021 14:43:24 +0100 Subject: ipa: rkisp1: Introduce IPAContext Before using any algorithm, we want the IPAContext to be ready for those. Introduce the IPAContext following the existing design from IPA::IPU3. Each algorithm will then introduce the needed fields.
