The driver requires to have a phandle reference to the Pensando System Controller. So the property like "amd,pensando-elba-syscon" is also needed to be added to the DT schema otherwise should the dt-schema tool correctly handle the "unevaluatedProperties: false" setting (Rob says it isn't fully supported at the moment), the dtbs_check procedure will fail on your dts evaluation. -Sergey > > reg: > minItems: 1 > -- > 2.17.1 >
