Subject: [PATCH] dt-bindings: i2c: convert to dt schema
Convert the NXP I2C controller for LPC2xxx/178x/18xx/43xx
to newer DT schema. Created DT schema based on the .txt file
which had `compatible`, `reg`, `interrupts`, `clocks`,
`#address-cells` and `#size-cells` as required properties.
Additional changes to the original .txt binding
- added maintainer from the MAINTAINERS file.
- added resets property required by the corresponding DTS files.

-NXP I2C controller for LPC2xxx/178x/18xx/43xx
-
-Required properties:
- - compatible: must be "nxp,lpc1788-i2c"
- - reg: physical address and length of the device registers
- - interrupts: a single interrupt specifier
- - clocks: clock for the device
- - #address-cells: should be <1>
- - #size-cells: should be <0>
-
-Optional properties:
-- clock-frequency: the desired I2C bus clock frequency in Hz; in
- absence of this property the default value is used (100 kHz).
-
-Example:
-i2c0: i2c@...a1000 {
- compatible = "nxp,lpc1788-i2c";
- reg = <0x400a1000 0x1000>;
- interrupts = <18>;
- clocks = <&ccu1 CLK_APB1_I2C0>;
- #address-cells = <1>;
- #size-cells = <0>;
-};
-
-&i2c0 {
- clock-frequency = <400000>;
-
- lm75@48 {
- compatible = "nxp,lm75";
- reg = <0x48>;
- };
