Subject: [PATCH] dt-bindings: i2c: meson: convert to yaml
Now that we have the DT validation in place, let's convert the device tree
bindings for the Amlogic I2C Controller over to YAML schemas.

-Amlogic Meson I2C controller
-
-Required properties:
- - compatible: must be:
- "amlogic,meson6-i2c" for Meson8 and compatible SoCs
- "amlogic,meson-gxbb-i2c" for GXBB and compatible SoCs
- "amlogic,meson-axg-i2c"for AXG and compatible SoCs
-
- - 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>
-
-For details regarding the following core I2C bindings see also i2c.txt.
-
-Optional properties:
-- clock-frequency: the desired I2C bus clock frequency in Hz; in
- absence of this property the default value is used (100 kHz).
-
-Examples:
-
- i2c@...00500 {
- compatible = "amlogic,meson6-i2c";
- reg = <0xc8100500 0x20>;
- interrupts = <0 92 1>;
- clocks = <&clk81>;
- #address-cells = <1>;
- #size-cells = <0>;
- };
