From 248374feca901d79c5df24b06e01fc0113e84638 Mon Sep 17 00:00:00 2001 From: Paul Elder Date: Wed, 13 Mar 2024 19:25:16 +0900 Subject: ipa: rkisp1: agc: Plumb mode-selection and frame duration controls Plumb controls for setting metering mode, exposure mode, constraint mode, and frame duration limits. Also report them as available controls, as well as in metadata. While at it, add the missing #include for tuple, as a std::tie is used.
