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.
|
