      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
