+      In PCIe mode one can choose to use an internal or an external reference
+      clock.
+      By default the internal clock is selected. The PCIe PHY provides a 100MHz
+      differential clock output(optional with SSC) for system applications.
+      When selecting this option an externally 100MHz differential
+      reference clock needs to be provided to the PCIe PHY.

- - samsung,cam1-sysreg - phandle to the CAM1 system registers controller
-
-For "samsung,s5pv210-mipi-video-phy" compatible PHYs the second cell in
-the PHY specifier identifies the PHY and its meaning is as follows:
-  0 - MIPI CSIS 0,
-  1 - MIPI DSIM 0,
-  2 - MIPI CSIS 1,
-  3 - MIPI DSIM 1.
-"samsung,exynos5420-mipi-video-phy" and "samsung,exynos5433-mipi-video-phy"
-supports additional fifth PHY:
-  4 - MIPI CSIS 2.
-
-Samsung Exynos SoC series Display Port PHY
--------------------------------------------------
-
-Required properties:
-- compatible : should be one of the following supported values:
-	 - "samsung,exynos5250-dp-video-phy"
-	 - "samsung,exynos5420-dp-video-phy"
-- samsung,pmu-syscon: phandle for PMU system controller interface, used to
-		      control pmu registers for power isolation.
-- #phy-cells : from the generic PHY bindings, must be 0;
-
-Samsung S5P/Exynos SoC series USB PHY
--------------------------------------------------
-
-Required properties:
-- compatible : should be one of the listed compatibles:
-	- "samsung,exynos3250-usb2-phy"
-	- "samsung,exynos4210-usb2-phy"
-	- "samsung,exynos4x12-usb2-phy"
-	- "samsung,exynos5250-usb2-phy"
-	- "samsung,exynos5420-usb2-phy"
-	- "samsung,s5pv210-usb2-phy"
-- reg : a list of registers used by phy driver
-	- first and obligatory is the location of phy modules registers
-- samsung,sysreg-phandle - handle to syscon used to control the system registers
-- samsung,pmureg-phandle - handle to syscon used to control PMU registers
-- #phy-cells : from the generic phy bindings, must be 1;
-- clocks and clock-names:
-	- the "phy" clock is required by the phy module, used as a gate
-	- the "ref" clock is used to get the rate of the clock provided to the
-	  PHY module
-
-Optional properties:
-- vbus-supply: power-supply phandle for vbus power source
-
-The first phandle argument in the PHY specifier identifies the PHY, its
-meaning is compatible dependent. For the currently supported SoCs (Exynos 4210
-and Exynos 4212) it is as follows:
-  0 - USB device ("device"),
-  1 - USB host ("host"),
-  2 - HSIC0 ("hsic0"),
-  3 - HSIC1 ("hsic1"),
-Exynos3250 has only USB device phy available as phy 0.
-
-Exynos 4210 and Exynos 4212 use mode switching and require that mode switch
-register is supplied.
-
-Example:
-
-For Exynos 4412 (compatible with Exynos 4212):
-
-usbphy: phy@125b0000 {
-	compatible = "samsung,exynos4x12-usb2-phy";
-	reg = <0x125b0000 0x100>;
-	clocks = <&clock 305>, <&clock 2>;
-	clock-names = "phy", "ref";
-	#phy-cells = <1>;
-	samsung,sysreg-phandle = <&sys_reg>;
-	samsung,pmureg-phandle = <&pmu_reg>;
-};
-
-Then the PHY can be used in other nodes such as:
-
-phy-consumer@12340000 {
-	phys = <&usbphy 2>;
-	phy-names = "phy";
-};
-
-Refer to DT bindings documentation of particular PHY consumer devices for more
-information about required PHYs and the way of specification.
-
-Samsung SATA PHY Controller
----------------------------
-
-SATA PHY nodes are defined to describe on-chip SATA Physical layer controllers.
-Each SATA PHY controller should have its own node.
-
-Required properties:
-- compatible        : compatible list, contains "samsung,exynos5250-sata-phy"
-- reg : offset and length of the SATA PHY register set;
-- #phy-cells : must be zero
-- clocks : must be exactly one entry
-- clock-names : must be "sata_phyctrl"
-- samsung,exynos-sataphy-i2c-phandle : a phandle to the I2C device, no arguments
-- samsung,syscon-phandle : a phandle to the PMU system controller, no arguments
-
-Example:
-	sata_phy: sata-phy@12170000 {
-		compatible = "samsung,exynos5250-sata-phy";
-		reg = <0x12170000 0x1ff>;
-		clocks = <&clock 287>;
-		clock-names = "sata_phyctrl";
-		#phy-cells = <0>;
-		samsung,exynos-sataphy-i2c-phandle = <&sata_phy_i2c>;
-		samsung,syscon-phandle = <&pmu_syscon>;
-	};
-
-Device-Tree bindings for sataphy i2c client driver
---------------------------------------------------
-
-Required properties:
-compatible: Should be "samsung,exynos-sataphy-i2c"
-- reg: I2C address of the sataphy i2c device.
-
-Example:
-
-	sata_phy_i2c:sata-phy@38 {
-		compatible = "samsung,exynos-sataphy-i2c";
-		reg = <0x38>;
-	};
-
-Samsung Exynos5 SoC series USB DRD PHY controller
---------------------------------------------------
-
-Required properties:
-- compatible : Should be set to one of the following supported values:
-	- "samsung,exynos5250-usbdrd-phy" - for exynos5250 SoC,
-	- "samsung,exynos5420-usbdrd-phy" - for exynos5420 SoC.
-	- "samsung,exynos5433-usbdrd-phy" - for exynos5433 SoC.
-	- "samsung,exynos7-usbdrd-phy" - for exynos7 SoC.
-- reg : Register offset and length of USB DRD PHY register set;
-- clocks: Clock IDs array as required by the controller
-- clock-names: names of clocks correseponding to IDs in the clock property;
-	       Required clocks:
-	- phy: main PHY clock (same as USB DRD controller i.e. DWC3 IP clock),
-	       used for register access.
-	- ref: PHY's reference clock (usually crystal clock), used for
-	       PHY operations, associated by phy name. It is used to
-	       determine bit values for clock settings register.
-	       For Exynos5420 this is given as 'sclk_usbphy30' in CMU.
-	- optional clocks: Exynos5433 & Exynos7 SoC has now following additional
-			   gate clocks available:
-			   - phy_pipe: for PIPE3 phy
-			   - phy_utmi: for UTMI+ phy
-			   - itp: for ITP generation
-- samsung,pmu-syscon: phandle for PMU system controller interface, used to
-		      control pmu registers for power isolation.
-- #phy-cells : from the generic PHY bindings, must be 1;
-
-For "samsung,exynos5250-usbdrd-phy" and "samsung,exynos5420-usbdrd-phy"
-compatible PHYs, the second cell in the PHY specifier identifies the
-PHY id, which is interpreted as follows:
-  0 - UTMI+ type phy,
-  1 - PIPE3 type phy,
-
-Example:
-	usbdrd_phy: usbphy@12100000 {
-		compatible = "samsung,exynos5250-usbdrd-phy";
-		reg = <0x12100000 0x100>;

-- aliases: For SoCs like Exynos5420 having multiple USB 3.0 DRD PHY controllers,
-	   'usbdrd_phy' nodes should have numbered alias in the aliases node,
-	   in the form of usbdrdphyN, N = 0, 1... (depending on number of
-	   controllers).
-Example:
-	aliases {
-		usbdrdphy0 = &usb3_phy0;
-		usbdrdphy1 = &usb3_phy1;
-	};
-
-Samsung Exynos SoC series PCIe PHY controller
---------------------------------------------------
-Required properties:
-- compatible : Should be set to "samsung,exynos5440-pcie-phy"
-- #phy-cells : Must be zero
-- reg : a register used by phy driver.
-	- First is for phy register, second is for block register.
-- reg-names : Must be set to "phy" and "block".
-
-Example:
-	pcie_phy0: pcie-phy@270000 {
-		#phy-cells = <0>;
-		compatible = "samsung,exynos5440-pcie-phy";
-		reg = <0x270000 0x1000>, <0x271000 0x40>;
-		reg-names = "phy", "block";
