MVEBU A3700 UTMI PHY |
|
-------------------- |
|
|
|
USB2 UTMI+ PHY controllers can be found on the following Marvell MVEBU SoCs: |
|
* Armada 3700 |
|
|
|
On Armada 3700, there are two USB controllers, one is compatible with the USB2 |
|
and USB3 specifications and supports OTG. The other one is USB2 compliant and |
|
only supports host mode. Both of these controllers come with a slightly |
|
different UTMI PHY. |
|
|
|
Required Properties: |
|
|
|
- compatible: Should be one of: |
|
* "marvell,a3700-utmi-host-phy" for the PHY connected to |
|
the USB2 host-only controller. |
|
* "marvell,a3700-utmi-otg-phy" for the PHY connected to |
|
the USB3 and USB2 OTG capable controller. |
|
- reg: PHY IP register range. |
|
- marvell,usb-misc-reg: handle on the "USB miscellaneous registers" shared |
|
region covering registers related to both the host |
|
controller and the PHY. |
|
- #phy-cells: Standard property (Documentation: phy-bindings.txt) Should be 0. |
|
|
|
|
|
Example: |
|
|
|
usb2_utmi_host_phy: phy@5f000 { |
|
compatible = "marvell,armada-3700-utmi-host-phy"; |
|
reg = <0x5f000 0x800>; |
|
marvell,usb-misc-reg = <&usb2_syscon>; |
|
#phy-cells = <0>; |
|
}; |
|
|
|
usb2_syscon: system-controller@5f800 { |
|
compatible = "marvell,armada-3700-usb2-host-misc", "syscon"; |
|
reg = <0x5f800 0x800>; |
|
};
