+* Mediatek's I2C controller
+
+The Mediatek's I2C controller is used to interface with I2C devices.
+
+Required properties:
+ - compatible: value should be either of the following.
+ (a) "mediatek,mt6577-i2c", for i2c compatible with mt6577 i2c.
+ (b) "mediatek,mt6589-i2c", for i2c compatible with mt6589 i2c.
+ (c) "mediatek,mt8127-i2c", for i2c compatible with mt8127 i2c.
+ (d) "mediatek,mt8135-i2c", for i2c compatible with mt8135 i2c.
+ (e) "mediatek,mt8173-i2c", for i2c compatible with mt8173 i2c.
+ - reg: physical base address of the controller and dma base, length of memory
+ mapped region.
+ - interrupts: interrupt number to the cpu.
+ - clock-div: the fixed value for frequency divider of clock source in i2c
+ module. Each IC may be different.
+ - clocks: clock name from clock manager
+ - clock-names: Must include "main" and "dma", if enable have-pmic need include
+ "pmic" extra.
+
+Optional properties:
+ - clock-frequency: Frequency in Hz of the bus when transfer, the default value
+ is 100000.
+ - mediatek,have-pmic: platform can control i2c form special pmic side.
+ Only mt6589 and mt8135 support this feature.
+ - mediatek,use-push-pull: IO config use push-pull mode.
+
+Example:
+
+ i2c0: i2c@1100d000 {
+ compatible = "mediatek,mt6577-i2c";
+ reg = <0x1100d000 0x70>,
