-Required properties:
-- compatible      : Must be "socionext,synquacer-i2c"
-- reg             : Offset and length of the register set for the device
-- interrupts      : A single 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@...10000 {
-        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>;
-    };
