In this case 'type: boolean'. Ping! And now Linus' tree is broken. If you can't be bothered to fix this, perhaps it should be reverted. Rob

This breaks linux-next and you didn't test with 'make dt_binding_check': /builds/robherring/linux-dt-bindings/Documentation/devicetree/bindings/spi/spi-fsl-lpspi.yaml: properties:fsl,spi-only-use-cs1-sel: {'description': 'spi common code does not support use of CS signals discontinuously. i.MX8DXL-EVK board only uses CS1 without using CS0. Therefore, add this property to re-config the chipselect value in the LPSPI driver.'} is not valid under any of the given schemas (Possible causes of the failure): /builds/robherring/linux-dt-bindings/Documentation/devicetree/bindings/spi/spi-fsl-lpspi.yaml: properties:fsl,spi-only-use-cs1-sel: 'not' is a required property The problem is you need a type definition for a vendor specific property. In this case 'type: boolean'. Rob
[PATCH V2 4/4] dt-bindings: lpspi: New property in document DT bindings for LPSPI
Add "fsl,spi-only-use-cs1-sel" to fit i.MX8DXL-EVK. Spi common code does not support use of CS signals discontinuously. It only uses CS1 without using CS0. So, add this property to re-config chipselect value.
