AM33XX MUSB GLUE
- compatible : Should be "ti,musb-am33xx"
- reg : offset and length of register sets, first usbss, then for musb instances
- interrupts : usbss, musb instance interrupts in order
- ti,hwmods : must be "usb_otg_hs"
- multipoint : Should be "1" indicating the musb controller supports
multipoint. This is a MUSB configuration-specific setting.
- num-eps : Specifies the number of endpoints. This is also a
MUSB configuration-specific setting. Should be set to "16"
- ram-bits : Specifies the ram address size. Should be set to "12"
- port0-mode : Should be "3" to represent OTG. "1" signifies HOST and "2"
represents PERIPHERAL.
- port1-mode : Should be "1" to represent HOST. "3" signifies OTG and "2"
represents PERIPHERAL.
- power : Should be "250". This signifies the controller can supply up to
500mA when operating in host mode.
Example:
usb@47400000 {
compatible = "ti,musb-am33xx";
reg = <0x47400000 0x1000 /* usbss */
0x47401000 0x800 /* musb instance 0 */
0x47401800 0x800>; /* musb instance 1 */
interrupts = <17 /* usbss */
18 /* musb instance 0 */
19>; /* musb instance 1 */
multipoint = <1>;
num-eps = <16>;
ram-bits = <12>;
port0-mode = <3>;
port1-mode = <3>;
power = <250>;
ti,hwmods = "usb_otg_hs";
};
