1 * Mediatek's I2C controller
3 The Mediatek's I2C controller is used to interface with I2C devices.
6 - compatible: value should be either of the following.
7 "mediatek,mt2701-i2c", "mediatek,mt6577-i2c": for Mediatek mt2701
8 "mediatek,mt6577-i2c": for i2c compatible with mt6577.
9 "mediatek,mt6589-i2c": for i2c compatible with mt6589.
10 "mediatek,mt7623-i2c", "mediatek,mt6577-i2c": for i2c compatible with mt7623.
11 "mediatek,mt8173-i2c": for i2c compatible with mt8173.
12 - reg: physical base address of the controller and dma base, length of memory
14 - interrupts: interrupt number to the cpu.
15 - clock-div: the fixed value for frequency divider of clock source in i2c
16 module. Each IC may be different.
17 - clocks: clock name from clock manager
18 - clock-names: Must include "main" and "dma", if enable have-pmic need include
22 - clock-frequency: Frequency in Hz of the bus when transfer, the default value
24 - mediatek,have-pmic: platform can control i2c form special pmic side.
25 Only mt6589 and mt8135 support this feature.
26 - mediatek,use-push-pull: IO config use push-pull mode.
