I though the compatible string was listed as a required property, but it is not. The 'reg' property however is listed as required, although the of_miodbus_register() works just fine without it, although that is a Linux-specific implementation detail. > > Define board specific delays to apply to RGMII signals. > > Signed-off-by: Boris BREZILLON <[email protected]> Reviewed-by: Florian Fainelli <[email protected]> > --- > arch/arm/boot/dts/sama5d3xcm.dtsi | 15 +++++++++++++++ > 1 file changed, 15 insertions(+) > > diff --git a/arch/arm/boot/dts/sama5d3xcm.dtsi > b/arch/arm/boot/dts/sama5d3xcm.dtsi > index b0b1331..fc68bae 100644 > --- a/arch/arm/boot/dts/sama5d3xcm.dtsi > +++ b/arch/arm/boot/dts/sama5d3xcm.dtsi > @@ -34,6 +34,21 @@ > > macb0: ethernet@f0028000 { > phy-mode = "rgmii"; > + #address-cells = <1>; > + #size-cells = <0>; > + > + ethernet-phy { > + interrupt-parent = <&pioB>; > + interrupts = <25 > IRQ_TYPE_EDGE_FALLING>; > + txen-skew-ps = <800>; > + txc-skew-ps = <3000>; > + rxdv-skew-ps = <400>; > + rxc-skew-ps = <3000>; > + rxd0-skew-ps = <400>; > + rxd1-skew-ps = <400>; > + rxd2-skew-ps = <400>; > + rxd3-skew-ps = <400>; > + }; > }; > > pmc: pmc@fffffc00 { > -- > 1.8.3.2 > > > _______________________________________________ > linux-arm-kernel mailing list > [email protected] > http://lists.infradead.org/mailman/listinfo/linux-arm-kernel -- Florian -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
