1 TI DA8xx MUSB
2 ~~~~~~~~~~~~~
3 For DA8xx/OMAP-L1x/AM17xx/AM18xx platforms.
5 Required properties:
6 ~~~~~~~~~~~~~~~~~~~~
7  - compatible : Should be set to "ti,da830-musb".
9  - reg: Offset and length of the USB controller register set.
11  - interrupts: The USB interrupt number.
13  - interrupt-names: Should be set to "mc".
15  - dr_mode: The USB operation mode. Should be one of "host", "peripheral" or "otg".
17  - phys: Phandle for the PHY device
19  - phy-names: Should be "usb-phy"
21  - dmas: specifies the dma channels
23  - dma-names: specifies the names of the channels. Use "rxN" for receive
24    and "txN" for transmit endpoints. N specifies the endpoint number.
26 Optional properties:
27 ~~~~~~~~~~~~~~~~~~~~
28  - vbus-supply: Phandle to a regulator providing the USB bus power.
30 DMA
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.
