The RT5640 GPIO1/IRQ pin can be configured either as GPIO1 or as the codec interrupt output. Some boards, such as the Firefly-RK3399, do not connect the codec interrupt output. This causes the following binding validation warning: 'interrupts' is a required property Make the interrupts property optional to support such hardware configurations.
