Add a binding for the I2C controller that can be found in the Socionext
SynQuacer SoC. Note that this is the exact same IP as the Fujitsu F_I2C.

+Socionext SynQuacer I2C
+
+Required properties:
+- compatible : Must be "socionext,synquacer-i2c"
+- reg : Offset and length of the register set for the device
+- interrupts : the interrupt specifier
+- #address-cells : Must be <1>;
+- #size-cells : Must be <0>;
+- clock-names : Must contain "pclk".
+- clocks : Must contain an entry for each name in clock-names.
+ (See the common clock bindings.)
+
+Optional properties:
+- clock-frequency : Desired I2C bus clock frequency in Hz. As only Normal and
+ Fast modes are supported, possible values are 100000 and
+ 400000.
+
+Example :
+
+ i2c@51210000 {
+ compatible = "socionext,synquacer-i2c";
+ reg = <0x51210000 0x1000>;
+ interrupts = <GIC_SPI 165 IRQ_TYPE_LEVEL_HIGH>;
+ #address-cells = <1>;
+ #size-cells = <0>;
+ clock-names = "pclk";
+ clocks = <&clk_i2c>;
+ clock-frequency = <400000>;
+ };
