Thus it is blocking the22 interrupt line which is usually bad for shared lines. By default,23 interrupts are disabled for this PHY and polling mode is used. If one24 can live with the consequences, this property can be used to enable25 interrupt handling.26 27 Affected PHYs (as far as known) are GPY215B and GPY215C.28 type: boolean29 30dependencies:31 maxlinear,use-broken-interrupts: [ interrupts ]32 33unevaluatedProperties: false34 35examples:36 - |37 ethernet {38 #address-cells = <1>;39 #size-cells = <0>;40 41 ethernet-phy@0 {42 reg = <0>;43 interrupts-extended = <&intc 0>;44 maxlinear,use-broken-interrupts;45 };46 };47 48...49
