Hi, I see you have already merged this, but FWIW HDMI works as well as before on exynos4412-i9300, so: Tested-by: Henrik Grimler <henrik@xxxxxxxxxx> Longer explanation: HDMI output only works on i9300 if MHL cable is attached before device boots, so probably bootloader sets up some settings that the sii9234 driver does not handle (correctly) if cable is hot plugged.
