From b9923747ad28bea8b9466c7205a0db4d56545716 Mon Sep 17 00:00:00 2001 From: Naushir Patuck Date: Mon, 23 Jan 2023 15:49:24 +0000 Subject: pipeline: ipa: raspberrypi: Validate lens controls Pass the available lens controls to the IPA through the configure() function. Validate that the V4L2_CID_FOCUS_ABSOLUTE does exist. If it doesn't, log a warning message, and do not advertise focus related controls from the IPA.
