 61                                 interrupt-parent = <&tegra_main_gpio>;
 62                                 interrupts = <TEGRA194_MAIN_GPIO(G, 4) IRQ_TYPE_LEVEL_LOW>;
 63                                 //marvell,copper-mode;
 64                                 micrel,copper-mode;
 65                                 /* Setup LED[2] as interrupt pin (active low) */
 66                                 //marvell,reg-init = <0x03 0x12 0x7fff 0x880>;
 67                                 micrel,reg-init = <0x03 0x12 0x7fff 0x880>;
