The actual binding in LP-8x4x is bigger: fpga@5 { compatible = "simple-bus"; #address-cells = <1>; #size-cells = <1>; ranges = <0 5 0x3000000 0x10000>; interrupt-parent = <&fpgairq>; rtc@901c { compatible = "dallas,rtc-ds1302"; reg = <0x901c 0x1>; status = "okay"; }; sram@a000 { compatible = "icpdas,sram-lp8x4x"; reg = <0xa000 0x1000 0x901e 0x1>; partitions { #address-cells = <1>; #size-cells = <1>; }; }; fpgairq: irq@9006 { compatible = "icpdas,irq-lp8x4x"; reg = <0x9006 0x16>; interrupt-parent = <&gpio>; interrupts = <3 IRQ_TYPE_EDGE_FALLING>; #interrupt-cells = <1>; interrupt-controller; status = "okay"; }; uart@9050 { compatible = "icpdas,uart-lp8x4x"; reg = <0x9050 0x10 0x9030 0x02>; interrupts = <13>; status = "okay"; }; uart@9060 { compatible = "icpdas,uart-lp8x4x"; reg = <0x9060 0x10 0x9032 0x02>; interrupts = <14>; status = "okay"; }; uart@9070 { compatible = "icpdas,uart-lp8x4x"; reg = <0x9070 0x10 0x9034 0x02>; interrupts = <15>; status = "okay"; }; backplane { compatible = "icpdas,backplane-lp8x4x"; reg = <0x0 0x2 0x1000 0x10 0x2000 0x10 0x3000 0x10 0x4000 0x10 0x5000 0x10 0x6000 0x10 0x7000 0x10 0x8000 0x10 0x9002 0x2 0x9004 0x2 0x9046 0x2>; eeprom-gpios = <&gpio 4 0>; }; }; -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
