1 TI DA8xx MUSB
2 ~~~~~~~~~~~~~
3 For DA8xx/OMAP-L1x/AM17xx/AM18xx platforms.
4
5 Required 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
26 Optional properties:
27 ~~~~~~~~~~~~~~~~~~~~
28 - vbus-supply: Phandle to a regulator providing the USB bus power.
29
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.
40 - #dma-channels: deprecated
