| |
Per the dt-binding the interrupt is optional so use platform_get_irq_optional() instead of platform_get_irq(). Since commit 7723f4c5ecdb ("driver core: platform: Add an error message to platform_get_irq*()") platform_get_irq() produces an error message
orion-mdio f1072004.mdio: IRQ index 0 not found
which is perfectly normal if one hasn't specified the optional property in the device tree.
