Yes, as we discussed many times - this is still needed even with the proper flags. > there would be no need to perform this in the driver. assigned-clock-xxx are not respecting that flag and anyway, even if that was solved, they are executed too early - before PHY is initialized. You cannot prepare PHY PLL before PHY is initialized and enabled. Best regards, Krzysztof
