Error when trying to compile the device table

ERROR (duplicate_label): Duplicate label ‘gpio’ on /gpio@6000d000 and /gpio@0,6000d000
Warning: Input tree has errors, output forced

I expect this error is caused by these lines
in tegra210.dtsi:
gpio: gpio@0,6000d000 {
compatible = “nvidia,tegra210-gpio”, “nvidia,tegra30-gpio”;
reg = <0x0 0x6000d000 0x0 0x1000>;
interrupts = <GIC_SPI 32 IRQ_TYPE_LEVEL_HIGH>,
<GIC_SPI 33 IRQ_TYPE_LEVEL_HIGH>,
<GIC_SPI 34 IRQ_TYPE_LEVEL_HIGH>,
<GIC_SPI 35 IRQ_TYPE_LEVEL_HIGH>,
<GIC_SPI 55 IRQ_TYPE_LEVEL_HIGH>,
<GIC_SPI 87 IRQ_TYPE_LEVEL_HIGH>,
<GIC_SPI 89 IRQ_TYPE_LEVEL_HIGH>,
<GIC_SPI 125 IRQ_TYPE_LEVEL_HIGH>;
#gpio-cells = <2>;
gpio-controller;

};

Any ideas on how to resolve this?
