From fedc77842eccddee89bfc70d614d744d9e6b8c2b Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Niklas=20S=C3=B6derlund?= Date: Wed, 12 Aug 2020 16:24:07 +0200 Subject: libcamera: pipeline: rkisp1: Setup links as part of configuration MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit In preparation of supporting both the main and self path configure all the media graph links as a part of the configuration step. Before this change the link between ISP and DMA engine was setup at match time as the only supported path was the main path and only the link between sensor and ISP was updated at part of the configuration step. The main path is still the only path between ISP and DMA engine that is possible to enable.
