You might notice that I am using a new macro for initializing the pll_video0_clk struct: New: SUNXI_CCU_NM_WITH_FRAC_GATE_LOCK_MIN_MAX_FEAT_NM_RATIO Old: SUNXI_CCU_NM_WITH_FRAC_GATE_LOCK_MIN_MAX_CLOSEST Setting the two CCU_FEATURE flags is part of the old initialization macro. I'll add SUNXI_CCU_NM_WITH_FRAC_GATE_LOCK_MIN_MAX_NM_RATIO_CLOSEST which hopefully resolves the confusion.
