- Subject: [PATCH 092/122] dt-bindings: qspi: cdns,qspi-nor: constrain
- minItems/maxItems of resets
- The QSPI controller needs three reset items to work properly on JH7110 SoC,
- so there is need to change the maxItems's value to 3 and add minItems
- whose value is equal to 2. Other platforms do not have this constraint.
