The 15*be470496SLinus Walleij device is always connected to the expansion bus of the IXP4xx SoCs using one 16*be470496SLinus Walleij or two chip select areas and address translating logic on the board. The 17*be470496SLinus Walleij node must be placed inside a chip select node on the IXP4xx expansion bus. 18*be470496SLinus Walleij 19*be470496SLinus Walleijproperties: 20*be470496SLinus Walleij compatible: 21*be470496SLinus Walleij const: intel,ixp4xx-compact-flash 22*be470496SLinus Walleij 23*be470496SLinus Walleij reg: 24*be470496SLinus Walleij items: 25*be470496SLinus Walleij - description: Command interface registers 26*be470496SLinus Walleij - description: Control interface registers 27*be470496SLinus Walleij 28*be470496SLinus Walleij interrupts: 29*be470496SLinus Walleij maxItems: 1 30*be470496SLinus Walleij 31*be470496SLinus Walleijrequired: 32*be470496SLinus Walleij - compatible 33*be470496SLinus Walleij - reg 34*be470496SLinus Walleij - interrupts 35*be470496SLinus Walleij 36*be470496SLinus WalleijallOf: 37*be470496SLinus Walleij - $ref: pata-common.yaml# 38*be470496SLinus Walleij 39*be470496SLinus WalleijunevaluatedProperties: false 40*be470496SLinus Walleij 41*be470496SLinus Walleijexamples: 42*be470496SLinus Walleij - | 43*be470496SLinus Walleij #include <dt-bindings/interrupt-controller/irq.h> 44*be470496SLinus Walleij 45*be470496SLinus Walleij bus@c4000000 { 46*be470496SLinus Walleij compatible = "intel,ixp43x-expansion-bus-controller", "syscon"; 47*be470496SLinus Walleij reg = <0xc4000000 0x1000>; 48*be470496SLinus Walleij native-endian; 49*be470496SLinus Walleij #address-cells = <2>; 50*be470496SLinus Walleij #size-cells = <1>; 51*be470496SLinus Walleij ranges = <0 0x0 0x50000000 0x01000000>, <1 0x0 0x51000000 0x01000000>; 52*be470496SLinus Walleij dma-ranges = <0 0x0 0x50000000 0x01000000>, <1 0x0 0x51000000 0x01000000>; 53*be470496SLinus Walleij ide@1,0 { 54*be470496SLinus Walleij compatible = "intel,ixp4xx-compact-flash"; 55*be470496SLinus Walleij reg = <1 0x00000000 0x1000>, <1 0x00040000 0x1000>; 56*be470496SLinus Walleij interrupt-parent = <&gpio0>; 57*be470496SLinus Walleij interrupts = <12 IRQ_TYPE_EDGE_RISING>; 58*be470496SLinus Walleij }; 59*be470496SLinus Walleij }; 60*be470496SLinus Walleij 61*be470496SLinus Walleij... 62
