From 10734a4eff943b4270e6a47bcbc14b09f08f252a Mon Sep 17 00:00:00 2001 From: Kieran Bingham Date: Mon, 13 Jul 2020 12:48:37 +0100 Subject: libcamera: pipeline: vivid: Initialise key controls The VIVID pipeline handler retains state globally of it's controls. Ensure that when we configure this specific pipeline we set initial parameters on the device that suit our (specific) needs. This introduces how controls can be set directly on a device, however under normal circumstances controls should usually be set from libcamera controls as part of a request. These are VIVID specific only.
