Any inputs?
I've checked this patchset on Exynos based Trats2 board (the one with simplest display pipeline: Exynos FIMD -> Exynos DSI -> s6e8aa0 DSI panel). DRM stops working after the 2nd patch ("[PATCH v3 2/7] drm: exynos: dsi: Use drm panel_bridge API"):
# dmesg | grep drm [ 2.511893] [drm] Exynos DRM: using 11c00000.fimd device for DMA mapping operations [ 2.518653] exynos-drm exynos-drm: bound 11c00000.fimd (ops fimd_component_ops) [ 2.535699] exynos-drm exynos-drm: bound 11c80000.dsi (ops exynos_dsi_component_ops) [ 2.543912] exynos-drm exynos-drm: [drm] Cannot find any crtc or sizes [ 2.556107] [drm] Initialized exynos 1.1.0 20180330 for exynos-drm on minor 0 [ 2.573212] exynos-dsi 11c80000.dsi: [drm:exynos_dsi_host_attach] *ERROR* failed to find the bridge: -19
Look like you have missed to apply the Child lookup patch. is it so?
Let me send it, I will CC you as well. And I will also send tc358764 panel_bridge conversion.
Thanks, Jagan.
