+TI DA8xx MUSB
+~~~~~~~~~~~~~
+For DA830 and DA850 platforms.
+
+Required properties:
+~~~~~~~~~~~~~~~~~~~~
+ - compatible : Should be set to "ti,da830-musb".
+
+ - reg: Offset and length of the USB controller register set.
+
+ - interrupts: The USB interrupt number.
+
+ - interrupt-names: Should be set to "mc".
+
+ - dr_mode: The USB operation mode. Should be one of "host", "peripheral" or
"otg".
+
+ - mentor,power : Specifies the maximum current in milliamperes the controller
can
+ supply in host mode.
+
+ - ti,phy20-refclock-frequency : Integer. Defines the USB 2.0 PHY reference
clock input
+ frequency in Hz in case the clock is generated by the internal PLL.
+ Supported values are 12MHz, 13MHz, 19.2MHz, 20MHz, 24MHz, 26MHz, 38.4MHz,
40MHz, 48MHz
+
+
+Optional properties:
+~~~~~~~~~~~~~~~~~~~~
+ - ti,phy20-clkmux-pll: Boolean. Defines the USB 2.0 PHY reference clock
source.
+ If present the internal PLL is used as a clock source, otherwise the
external
+ USB_REFCLKIN pin is used.
+
+Example:
+
+ usb20: usb@1e00000 {
+ compatible = "ti,da830-musb";
+ reg = <0x00200000 0x10000>;
+ interrupt-parent = <&intc>;
+ interrupts = <58>;
+ interrupt-names = "mc";
+
+ dr_mode = "host";
+ mentor,power = <500>;
+
+ ti,phy20-clkmux-pll;
+ ti,phy20-refclock-frequency = <24000000>;
+
+ status = "okay";
+ };
