Commit a6f75aa161c5 ("drm/exynos: fimd: add HW trigger support") added hardware trigger support to the FIMD controller driver. I have tested but this broke the display in at least the exynos3250 Gear 2. So until the issue is fixed, avoid using HW trigger for the exynos3250 based boards and use SW trigger as it was before the mentioned commit.
