I'm mildly surprised you need to turn on the gate to the PLL0 out, but not the div_out. The div_out/div_clk is also fed into every RCG that exists in the MMCC. Per the frequency plan the following RCGs require it - cci cpp fd_core camss_gp[0-1] jpeg0 mclk[0-3] csi[0-2]phytimer dp_gtc maxi axi ahb Also, I'm very interested in all things 8998, and would generally appreciate being added to the to: list.
