Driver for Broadcom Northstar USB 2.0 PHY |
|
|
|
Required properties: |
|
- compatible: brcm,ns-usb2-phy |
|
- reg: iomem address range of DMU (Device Management Unit) |
|
- reg-names: "dmu", the only needed & supported reg right now |
|
- clocks: USB PHY reference clock |
|
- clock-names: "phy-ref-clk", the only needed & supported clock right now |
|
|
|
To initialize USB 2.0 PHY driver needs to setup PLL correctly. To do this it |
|
requires passing phandle to the USB PHY reference clock. |
|
|
|
Example: |
|
usb2-phy { |
|
compatible = "brcm,ns-usb2-phy"; |
|
reg = <0x1800c000 0x1000>; |
|
reg-names = "dmu"; |
|
#phy-cells = <0>; |
|
clocks = <&genpll BCM_NSP_GENPLL_USB_PHY_REF_CLK>; |
|
clock-names = "phy-ref-clk"; |
|
};
