This also does nothing because you just duplicated the top-level constraints. If you have 2, then you want just 'minItems: 2'. Rob

Thank you for pointing out the problem for me. Best regards, Walker

The DMA controller needs two reset items to work properly on JH7110 SoC, so there is need to change the maxItems' value to 2 and add minItems whose value is equal to 1. Other platforms do not have this constraint.
