+EEPROM / CSR SMBus-slave interface of IDT 89HPESx devices
+
+Required properties:
+  - compatible : should be "<manufacturer>,<type>"
+		 Basically there is only one manufacturer: idt, but some
+		 compatible devices may be produced in future. Following devices
+		 are supported: 89hpes8nt2, 89hpes12nt3, 89hpes24nt6ag2,
+		 89hpes32nt8ag2, 89hpes32nt8bg2, 89hpes12nt12g2, 89hpes16nt16g2,
+		 89hpes24nt24g2, 89hpes32nt24ag2, 89hpes32nt24bg2;
+		 89hpes12n3, 89hpes12n3a, 89hpes24n3, 89hpes24n3a;
+		 89hpes32h8, 89hpes32h8g2, 89hpes48h12, 89hpes48h12g2,
+		 89hpes48h12ag2, 89hpes16h16, 89hpes22h16, 89hpes22h16g2,
+		 89hpes34h16, 89hpes34h16g2, 89hpes64h16, 89hpes64h16g2,
+		 89hpes64h16ag2;
+		 89hpes12t3g2, 89hpes24t3g2, 89hpes16t4, 89hpes4t4g2,

+		 89hpes48t12, 89hpes48t12g2.
+  - reg :	 I2C address of the IDT 89HPESx device.
+
+Optionally there can be EEPROM-compatible subnode:
+  - compatible:  There are five EEPROM devices supported: 24c32, 24c64, 24c128,
+		 24c256 and 24c512 differed by size.
+  - reg:         Custom address of EEPROM device (If not specified IDT 89HPESx
+    (optional)	 device will try to communicate with EEPROM sited by default
+		 address - 0x50)
+  - read-only :	 Parameterless property disables writes to the EEPROM
+    (optional)
+
+Example:
+	idt@60 {
+		compatible = "idt,89hpes32nt8ag2";
+		reg = <0x74>;
+		#address-cells = <1>;
+		#size-cells = <0>;
+
+		eeprom@50 {
+			compatible = "onsemi,24c64";
+			reg = <0x50>;
+			read-only;
+		};
+	};

 Freescale i.MX6 On-Chip OTP Controller (OCOTP) device tree bindings
 
 This binding represents the on-chip eFuse OTP controller found on
-i.MX6Q/D, i.MX6DL/S, i.MX6SL, and i.MX6SX SoCs.
+i.MX6Q/D, i.MX6DL/S, i.MX6SL, i.MX6SX and i.MX6UL SoCs.
 
 Required properties:
 - compatible: should be one of
 	"fsl,imx6q-ocotp" (i.MX6Q/D/DL/S),
 	"fsl,imx6sl-ocotp" (i.MX6SL), or
-	"fsl,imx6sx-ocotp" (i.MX6SX), followed by "syscon".
+	"fsl,imx6sx-ocotp" (i.MX6SX),
+	"fsl,imx6ul-ocotp" (i.MX6UL),
+	followed by "syscon".
 - reg: Should contain the register base and length.
 - clocks: Should contain a phandle pointing to the gated peripheral clock.
