From 04bec005b049604f862765b35ebd71c2a69b9e7c Mon Sep 17 00:00:00 2001 From: Maxime Ripard Date: Fri, 17 Feb 2023 13:38:10 +0100 Subject: [PATCH] drm/vc4: tests: Add BCM2712 mock driver The BCM2712 has a simpler pipeline that can only output to a writeback connector and two HDMI controllers. Let's allow our kunit tests to create a mock of that pipeline.
