|
||
|
|
~~~~~~~~~~~~~
|
||
|
|
For DA8xx/OMAP-L1x/AM17xx/AM18xx platforms.
|
||
|
|
|
||
|
|
Required properties:
|
||
|
|
~~~~~~~~~~~~~~~~~~~~
|
||
|
|
- compatible : Should be set to "ti,da830-musb".
|
||
|
|
|
||
|
|
- reg: Offset and length of the USB controller register set.
|
||
|
|
|
||
|
|
- interrupts: The USB interrupt number.
|
||
|
|
|
||
|
|
- interrupt-names: Should be set to "mc".
|
||
|
|
|
||
|
|
- dr_mode: The USB operation mode. Should be one of "host", "peripheral" or "otg".
|
||
|
|
|
||
|
|
- phys: Phandle for the PHY device
|
||
|
|
|
||
|
|
- phy-names: Should be "usb-phy"
|
||
|
|
|
||
|
|
- dmas: specifies the dma channels
|
||
|
|
|
||
|
|
- dma-names: specifies the names of the channels. Use "rxN" for receive
|
||
|
|
and "txN" for transmit endpoints. N specifies the endpoint number.
|
||
|
|
|
||
|
|
Optional properties:
|
||
|
|
~~~~~~~~~~~~~~~~~~~~
|
||
|
|
- vbus-supply: Phandle to a regulator providing the USB bus power.

DMA
|
||
|
|
~~~
|
||
|
|
- compatible: ti,da830-cppi41
|
||
|
|
- reg: offset and length of the following register spaces: CPPI DMA Controller,
|
||
|
|
CPPI DMA Scheduler, Queue Manager
|
||
|
|
- reg-names: "controller", "scheduler", "queuemgr"
|
||
|
|
- #dma-cells: should be set to 2. The first number represents the
|
||
|
|
channel number (0 … 3 for endpoints 1 … 4).
|
||
|
|
The second number is 0 for RX and 1 for TX transfers.
|
||
|
|
- #dma-channels: should be set to 4 representing the 4 endpoints.
