Kirkwood:

                mdio: mdio-bus@72004 {
                        compatible = "marvell,orion-mdio";
                        #address-cells = <1>;
                        #size-cells = <0>;
                        reg = <0x72004 0x84>;
                        interrupts = <46>;
                        clocks = <&gate_clk 0>;
                        status = "disabled";

Does this work? There is no clock-names in DT.

Neither are the clocks in Armada 7k8k / CN913x:

                CP11X_LABEL(mdio): mdio@12a200 {
                        #address-cells = <1>;
                        #size-cells = <0>;
                        compatible = "marvell,orion-mdio";
                        reg = <0x12a200 0x10>;
                        clocks = <&CP11X_LABEL(clk) 1 9>,
<&CP11X_LABEL(clk) 1 5>,
                                 <&CP11X_LABEL(clk) 1 6>,
<&CP11X_LABEL(clk) 1 18>;
                        status = "disabled";
                };

Apparently I misread the code and got convinced that contrary to
devm_clk_get_optional(), the devm_clk_get_bulk_optional() obtains the
clocks directly by index, not name (on the tested boards, the same
clocks are enabled by the other interfaces, so the problems

I will drop this patch. Thank you for spotting the issue.
