1TI DA8xx MUSB 2~~~~~~~~~~~~~ 3For DA8xx/OMAP-L1x/AM17xx/AM18xx platforms. 4 5Required properties: 6~~~~~~~~~~~~~~~~~~~~ 7 - compatible : Should be set to "ti,da830-musb". 8 9 - reg: Offset and length of the USB controller register set. 10 11 - interrupts: The USB interrupt number. 12 13 - interrupt-names: Should be set to "mc". 14 15 - dr_mode: The USB operation mode. Should be one of "host", "peripheral" or "otg". 16 17 - phys: Phandle for the PHY device 18 19 - phy-names: Should be "usb-phy" 20 21 - dmas: specifies the dma channels 22 23 - dma-names: specifies the names of the channels. Use "rxN" for receive 24 and "txN" for transmit endpoints. N specifies the endpoint number. 25 26Optional properties: 27~~~~~~~~~~~~~~~~~~~~ 28 - vbus-supply: Phandle to a regulator providing the USB bus power. 29 30DMA 31~~~ 32- compatible: ti,da830-cppi41 33- reg: offset and length of the following register spaces: CPPI DMA Controller, 34 CPPI DMA Scheduler, Queue Manager 35- reg-names: "controller", "scheduler", "queuemgr" 36- #dma-cells: should be set to 2. The first number represents the 37 channel number (0 … 3 for endpoints 1 … 4). 38 The second number is 0 for RX and 1 for TX transfers. 39- dma-channels: should be set to 4 representing the 4 endpoints. 40- #dma-channels: deprecated 41 42Example: 43 usb_phy: usb-phy { 44 compatible = "ti,da830-usb-phy"; 45 #phy-cells = <0>; 46 }; 47 usb0: usb@200000 { 48 compatible = "ti,da830-musb"; 49 reg = <0x00200000 0x1000>; 50 ranges; 51 #address-cells = <1>; 52 #size-cells = <1>; 53 interrupts = <58>; 54 interrupt-names = "mc"; 55 56 dr_mode = "host"; 57 vbus-supply = <&usb_vbus>; 58 phys = <&usb_phy 0>; 59 phy-names = "usb-phy"; 60 61 dmas = <&cppi41dma 0 0 &cppi41dma 1 0 62 &cppi41dma 2 0 &cppi41dma 3 0 63 &cppi41dma 0 1 &cppi41dma 1 1 64 &cppi41dma 2 1 &cppi41dma 3 1>; 65 dma-names = 66 "rx1", "rx2", "rx3", "rx4", 67 "tx1", "tx2", "tx3", "tx4"; 68 69 70 cppi41dma: dma-controller@201000 { 71 compatible = "ti,da830-cppi41"; 72 reg = <0x201000 0x1000 73 0x202000 0x1000 74 0x204000 0x4000>; 75 reg-names = "controller", "scheduler", "queuemgr"; 76 interrupts = <58>; 77 #dma-cells = <2>; 78 dma-channels = <4>; 79 }; 80 81 };
