3 - compatible: ti,am33xx-usb
4 - reg: offset and length of the usbss register sets
5 - ti,hwmods : must be "usb_otg_hs"
7 The glue layer contains multiple child nodes. It is required to have
8 at least a control module node, USB node and a PHY node. The second USB
9 node and its PHY node are optional. The DMA node is also optional.
13 - compatible: ti,am335x-usb-ctrl-module
14 - reg: offset and length of the "USB control registers" in the "Control
15 Module" block. A second offset and length for the USB wake up control
16 in the same memory block.
17 - reg-names: "phy_ctrl" for the "USB control registers" and "wakeup" for
18 the USB wake up control register.
22 compatible: ti,am335x-usb-phy
23 reg: offset and length of the "USB PHY" register space
24 ti,ctrl_mod: reference to the "reset module" node
26 The PHY should have a "phy" alias numbered properly in the alias
31 - compatible: ti,musb-am33xx
32 - reg: offset and length of "USB Controller Registers", and offset and
33 length of "USB Core" register space.
34 - reg-names: control for the ""USB Controller Registers" and "mc" for
35 "USB Core" register space
36 - interrupts: USB interrupt number
38 - dr_mode: Should be one of "host", "peripheral" or "otg".
39 - mentor,multipoint: Should be "1" indicating the musb controller supports
40 multipoint. This is a MUSB configuration-specific setting.
41 - mentor,num-eps: Specifies the number of endpoints. This is also a
42 MUSB configuration-specific setting. Should be set to "16"
43 - mentor,ram-bits: Specifies the ram address size. Should be set to "12"
44 - mentor,power: Should be "500". This signifies the controller can supply up to
45 500mA when operating in host mode.
46 - phys: reference to the USB phy
47 - dmas: specifies the dma channels
48 - dma-names: specifies the names of the channels. Use "rxN" for receive
49 and "txN" for transmit endpoints. N specifies the endpoint number.
51 The controller should have an "usb" alias numbered properly in the alias
56 - compatible: ti,am3359-cppi41
57 - reg: offset and length of the following register spaces: USBSS, USB
58 CPPI DMA Controller, USB CPPI DMA Scheduler, USB Queue Manager
59 - reg-names: glue, controller, scheduler, queuemgr
60 - #dma-cells: should be set to 2. The first number represents the
61 endpoint number (0 … 14 for endpoints 1 … 15 on instance 0 and 15 … 29
62 for endpoints 1 … 15 on instance 1). The second number is 0 for RX and
64 - #dma-channels: should be set to 30 representing the 15 endpoints for
