It can be dropped, I guess? > Actually, I did drop this in version 1. But when I added the imx8ulp compatible property to the fsl,fec.yaml, the maintainer expected imx8ulp to be compatible with imx6ul and with imx6q. The patch of fsl,fec.yaml as follows: --- a/Documentation/devicetree/bindings/net/fsl,fec.yaml +++ b/Documentation/devicetree/bindings/net/fsl,fec.yaml @@ -58,6 +58,11 @@ properties: - fsl,imx8qxp-fec - const: fsl,imx8qm-fec - const: fsl,imx6sx-fec + - items: + - enum: + - fsl,imx8ulp-fec + - const: fsl,imx6ul-fec + - const: fsl,imx6q-fec For compliant with the fsl,fec.yaml, so I added the imx6q-fec in the later version. And the patch of the fsl,fec.yaml has already applied to the upstream kernel. Therefore, I think it does not matter if the imx6q-fec is added. > Shawn > > > + reg = <0x29950000 0x10000>; > > + interrupts = <GIC_SPI 107 IRQ_TYPE_LEVEL_HIGH>; > > + interrupt-names = "int0"; > > + fsl,num-tx-queues = <1>; > > + fsl,num-rx-queues = <1>; > > + status = "disabled"; > > + }; > > }; > > > > gpioe: gpio@2d000080 { > > -- > > 2.25.1 > >
