From e1ca213609abb99cc1b6e6f16214bf5a0936f3b7 Mon Sep 17 00:00:00 2001 From: Laurent Pinchart Date: Tue, 2 Aug 2022 03:27:52 +0300 Subject: ipa: ipu3: Add YAML tuning file support Replace the manual instantiation of algorithms with an automatic mechanism based on a tuning data file, provided by the Module base class. This brings the IPU3 IPA module in line with the RkISP1 IPA module.
