-Samsung S5P/EXYNOS SoC series USB PHY
--------------------------------------------------
-
-Required properties:
-- compatible : should be one of the listed compatibles:
- - "samsung,exynos4210-usbphy"
- - "samsung,exynos4212-usbphy"
-- reg : a list of registers used by phy driver
- - first and obligatory is the location of phy modules registers
- - second and also required is the location of isolation registers
- (isolation registers control the physical connection between the in
- SoC modules and outside of the SoC, this also can be called enable
- control in the documentation of the SoC)
- - third is the location of the mode switch register, this only applies
- to SoCs that have such a feature; mode switching enables to have
- both host and device used the same SoC pins and is commonly used
- when OTG is supported
-- #phy-cells : from the generic phy bindings, must be 1;
-
-The second cell in the PHY specifier identifies the PHY its meaning is SoC
-dependent. For the currently supported SoCs (Exynos 4210 and Exynos 4212) it
-is as follows:
- 0 - USB device,
- 1 - USB host,
- 2 - HSIC0,
- 3 - HSIC1,
-
-Example:
-
-For Exynos 4412 (compatible with Exynos 4212):
-
-exynos_usbphy: exynos-usbphy@125B0000 {
- compatible = "samsung,exynos4212-usbphy";
- reg = <0x125B0000 0x100>, <0x10020704 0x0c>, <0x1001021c 0x4>;
- clocks = <&clock 305>, <&clock 2>, <&clock 2>, <&clock 2>,
- <&clock 2>;
- clock-names = "phy", "device", "host", "hsic0", "hsic1";
- status = "okay";
- #phy-cells = <1>;
-};
-
-Then the PHY can be used in other nodes such as:
-
-ehci@12580000 {
- status = "okay";
- phys = <&exynos_usbphy 2>;
- phy-names = "hsic0";
-};
