| OMAP GLUE AND OTHER OMAP SPECIFIC COMPONENTS |
| |
| OMAP MUSB GLUE |
| - compatible : Should be "ti,omap4-musb" or "ti,omap3-musb" |
| - ti,hwmods : must be "usb_otg_hs" |
| - ti,has-mailbox : to specify that omap uses an external mailbox |
| (in control module) to communicate with the musb core during device connect |
| and disconnect. |
| - 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" |
| - interface_type : This is a board specific setting to describe the type of |
| interface between the controller and the phy. It should be "0" or "1" |
| specifying ULPI and UTMI respectively. |
| - mode : Should be "3" to represent OTG. "1" signifies HOST and "2" |
| represents PERIPHERAL. |
| - power : Should be "50". This signifies the controller can supply upto |
| 100mA when operating in host mode. |
| |
| Optional properties: |
| - ctrl-module : phandle of the control module this glue uses to write to |
| mailbox |
| |
| SOC specific device node entry |
| usb_otg_hs: usb_otg_hs@4a0ab000 { |
| compatible = "ti,omap4-musb"; |
| ti,hwmods = "usb_otg_hs"; |
| ti,has-mailbox; |
| multipoint = <1>; |
| num_eps = <16>; |
| ram_bits = <12>; |
| ctrl-module = <&omap_control_usb>; |
| }; |
| |
| Board specific device node entry |
| &usb_otg_hs { |
| interface_type = <1>; |
| mode = <3>; |
| power = <50>; |
| }; |
| |
| OMAP CONTROL USB |
| |
| Required properties: |
| - compatible: Should be "ti,omap-control-usb" |
| - reg : Address and length of the register set for the device. It contains |
| the address of "control_dev_conf" and "otghs_control" or "phy_power_usb" |
| depending upon omap4 or omap5. |
| - reg-names: The names of the register addresses corresponding to the registers |
| filled in "reg". |
| - ti,type: This is used to differentiate whether the control module has |
| usb mailbox or usb3 phy power. omap4 has usb mailbox in control module to |
| notify events to the musb core and omap5 has usb3 phy power register to |
| power on usb3 phy. Should be "1" if it has mailbox and "2" if it has usb3 |
| phy power. |
| |
| omap_control_usb: omap-control-usb@4a002300 { |
| compatible = "ti,omap-control-usb"; |
| reg = <0x4a002300 0x4>, |
| <0x4a00233c 0x4>; |
| reg-names = "control_dev_conf", "otghs_control"; |
| ti,type = <1>; |
| }; |
