| TI DA8xx MUSB |
| ~~~~~~~~~~~~~ |
| 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. |
| |
