Thus it is blocking the 22 interrupt line which is usually bad for shared lines. By default, 23 interrupts are disabled for this PHY and polling mode is used. If one 24 can live with the consequences, this property can be used to enable 25 interrupt handling. 26 27 Affected PHYs (as far as known) are GPY215B and GPY215C. 28 type: boolean 29 30dependencies: 31 maxlinear,use-broken-interrupts: [ interrupts ] 32 33unevaluatedProperties: false 34 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
