+TI DaVinci DA8xx USB PHY
DA8xx is not DaVinci, please omit this.
+
+Required properties:
+ - compatible: must be "ti,da830-usbphy".
+ - #phy-cells: must be 1.
+
+This device controls the PHY for both the USB 1.1 OHCI and USB 2.0 OTG
+controllers on DA8xx SoCs. Consumers of this device should use index 0 for
+the USB 2.0 phy device and index 1 for the USB 1.1 phy device.
Not indices 2 and 1 already?
+It also requires a "syscon" node with compatible = "ti,da830-cfgchip", "syscon"
+to access the CFGCHIP2 register.
+
+Example:
+
+ cfgchip: cfgchip@1417c {
+ compatible = "ti,da830-cfgchip", "syscon";
+ reg = <0x1417c 0x14>;
+ };
+
+ usbphy: usbphy {
Name it "usb-phy" please, consistent to what ePAPR has mandated for
Ethernet PHYs.
[...]
MBR, Sergei
