1OCTEON/OCTEON+ USB BLOCK2 31) Main node4 5 Required properties:6 7 - compatible: must be "cavium,octeon-5750-usbn"8 9 - reg: specifies the physical base address of the USBN block and10 the length of the memory mapped region.11 12 - #address-cells: specifies the number of cells needed to encode an13 address. The value must be 2.14 15 - #size-cells: specifies the number of cells used to represent the size16 of an address. The value must be 2.17 18 - ranges: specifies the translation between child address space and parent19 address space.20 21 - clock-frequency: speed of the USB reference clock. Allowed values are22 12000000, 24000000 or 48000000.23 24 - cavium,refclk-type: type of the USB reference clock. Allowed values are25 "crystal" or "external".26 27 - refclk-frequency: deprecated, use "clock-frequency".28 29 - refclk-type: deprecated, use "cavium,refclk-type".30 312) Child node32 33 The main node must have one child node which describes the built-in34 USB controller.35 36 Required properties:37 38 - compatible: must be "cavium,octeon-5750-usbc"39 40 - reg: specifies the physical base address of the USBC block and41 the length of the memory mapped region.42 43 - interrupts: specifies the interrupt number for the USB controller.44 453) Example:46 47 usbn: usbn@1180068000000 {48 compatible = "cavium,octeon-5750-usbn";49 reg = <0x11800 0x68000000 0x0 0x1000>;50 ranges; /* Direct mapping */51 #address-cells = <2>;52 #size-cells = <2>;53 clock-frequency = <12000000>;54 cavium,refclk-type = "crystal";55 56 usbc@16f0010000000 {57 compatible = "cavium,octeon-5750-usbc";58 reg = <0x16f00 0x10000000 0x0 0x80000>;59 interrupts = <0 56>;60 };61 };62 63
