From 5aff27a20d718b05d20b9ce63d8b02a0b3bf9cb9 Mon Sep 17 00:00:00 2001 From: Naushir Patuck Date: Tue, 16 Feb 2021 08:55:05 +0000 Subject: ipa: raspberrypi: Fix exposure and gain delays for imx477 The exposure and gain delays for imx477 are both 2 frames. This error was not noticeable because the controller was using the embedded metadata to get the exposure and gain values for the frame.
