Yes I will set the proper mask for each as per the Exynos 5422 User Manual. Here is what I feel CLK_GATE_BUS_FSYS0 controls the PHY clock CLK_GATE_IP_FSYS controls the IP clock.

I am not sure if I understand your problem. I mentioned that you need to put proper registers with proper masks into the exynos5_subcmu_reg_dump. I don't know what have you changed to produce such error logs. Best regards, Krzysztof
