+* Samsung's usb phy transceiver
+
+The Samsung's phy transceiver is used for controlling usb phy for
+s3c-hsotg as well as ehci-s5p and ohci-exynos usb controllers
+across Samsung SOCs.
+TODO: Adding the PHY binding with controller(s) according to the under
+developement generic PHY driver.
+
+Required properties:
+
+Exynos4210:
+- compatible : should be "samsung,exynos4210-usbphy"
+- reg : base physical address of the phy registers and length of memory mapped
+ region.
+
+Exynos5250:
+- compatible : should be "samsung,exynos5250-usbphy"
+- reg : base physical address of the phy registers and length of memory mapped
+ region.
+
+Optional properties:
+- #address-cells: should be '1' when usbphy node has a child node with 'reg'
+ property.
+- #size-cells: should be '1' when usbphy node has a child node with 'reg'
+ property.
+- ranges: allows valid translation between child's address space and parent's
+ address space.
+
+- The child node 'usbphy-sys' to the node 'usbphy' is for the system controller
+ interface for usb-phy. It should provide the following information required by
+ usb-phy controller to control phy.
+ - reg : base physical address of PHY_CONTROL registers.
+ The size of this register is the total sum of size of all PHY_CONTROL
+ registers that the SoC has. For example, the size will be
+ '0x4' in case we have only one PHY_CONTROL register (e.g.
+ OTHERS register in S3C64XX or USB_PHY_CONTROL register in S5PV210)
+ and, '0x8' in case we have two PHY_CONTROL registers (e.g.
+ USBDEVICE_PHY_CONTROL and USBHOST_PHY_CONTROL registers in exynos4x).
+ and so on.
+
+Example:
+ - Exynos4210
+
+ usbphy@125B0000 {
+ #address-cells = <1>;
+ #size-cells = <1>;
+ compatible = "samsung,exynos4210-usbphy";

+ ranges;
+
+ usbphy-sys {
+ /* USB device and host PHY_CONTROL registers */
+ reg = <0x10020704 0x8>;
+ };
