   4 Subject: [PATCH 092/122] dt-bindings: qspi: cdns,qspi-nor: constrain
   5  minItems/maxItems of resets
   6
   7 The QSPI controller needs three reset items to work properly on JH7110 SoC,
   8 so there is need to change the maxItems's value to 3 and add minItems
   9 whose value is equal to 2. Other platforms do not have this constraint.
