OMAP USB2 PHY
Required properties:
- compatible: Should be "ti,omap-usb2"
Should be "ti,dra7x-usb2" for the 1st instance of USB2 PHY on
DRA7x
Should be "ti,dra7x-usb2-phy2" for the 2nd instance of USB2 PHY
in DRA7x
Should be "ti,am654-usb2" for the USB2 PHYs on AM654.
- reg : Address and length of the register set for the device.
- #phy-cells: determine the number of cells that should be given in the
phandle while referencing this phy.
- clocks: a list of phandles and clock-specifier pairs, one for each entry in
clock-names.
- clock-names: should include:
* "wkupclk" - wakeup clock.
* "refclk" - reference clock (optional).
Deprecated properties:
- ctrl-module : phandle of the control module used by PHY driver to power on
the PHY.
Recommended properies:
- syscon-phy-power : phandle/offset pair. Phandle to the system control
module and the register offset to power on/off the PHY.
This is usually a subnode of ocp2scp to which it is connected.
