From a5877e03072c9578cd97a84f4db1106f24a588a9 Mon Sep 17 00:00:00 2001 From: Laurent Pinchart Date: Tue, 1 Mar 2022 22:35:16 +0200 Subject: utils: rkisp1: Support optional CSI-2 receiver subdev The media graph may include a CSI-2 receiver entity between the sensor and the ISP for platforms that have a CSI-2 receiver external to the ISP. Support this by configuring the pipeline accordingly.
