1GHz? I can't seem to make the ethernet driver work unless I set it to 1GHz. This also makes other derived clocks that should be 125MHz show up as such in the clock tree. Eg. "usb_125m". Perhaps it's because I updated my board to the latest u-boot release[1]. I know these PLLs are just placeholders until you add proper code to control them, but until then it's important that these values match the defaults or whatever the latest u-boot sets them to. Please check the PLLs below with the latest u-boot too. /Emil [1]: https://github.com/starfive-tech/VisionFive2/releases > + /* 24MHz -> 1066.0MHz */ > + priv->pll[1] = devm_clk_hw_register_fixed_factor(priv->dev, "pll1_out", > + "osc", 0, 533, 12);
