From 485f92ac066388c4fa40a4c52cee76c5078b2d06 Mon Sep 17 00:00:00 2001 From: Umang Jain Date: Thu, 26 Sep 2024 15:06:22 +0530 Subject: libcamera: rkisp1: Prepare for additional camera controls Currently the rkisp1 pipeline handler only registers controls that are related to the IPA. This patch prepares the rkisp1 pipeline-handler to register camera controls which are not related to the IPA. Hence, introduce an additional ControlInfoMap for IPA controls. These controls will be merged together with the controls in the pipeline handler (introduced subsequently) as part of updateControls() and together will be registered during the registration of the camera. This is similar to what IPU3 pipeline handler handles its controls.
