The non-mechanincal exynos # changes are mostly fixes for new feature recently introduced. # # Apart from the exynos updates, we have: # # i915: # - GVT and GGTT mapping fixes # # amdgpu: # - fix HDMI2.0 4K@60 Hz regression # - Hotplug fixes for dual-GPU laptops to make power management better # - misc vega12 bios fixes, a race fix and some typos. # # sii8620 bridge: # - small fixes around
