|  | * Marvell MV64XXX I2C controller | 
|  |  | 
|  | Required properties : | 
|  |  | 
|  | - reg             : Offset and length of the register set for the device | 
|  | - compatible      : Should be either: | 
|  | - "allwinner,sun4i-a10-i2c" | 
|  | - "allwinner,sun6i-a31-i2c" | 
|  | - "marvell,mv64xxx-i2c" | 
|  | - "marvell,mv78230-i2c" | 
|  | - "marvell,mv78230-a0-i2c" | 
|  | * Note: Only use "marvell,mv78230-a0-i2c" for a | 
|  | very rare, initial version of the SoC which | 
|  | had broken offload support.  Linux | 
|  | auto-detects this and sets it appropriately. | 
|  | - interrupts      : The interrupt number | 
|  |  | 
|  | Optional properties : | 
|  |  | 
|  | - clock-frequency : Desired I2C bus clock frequency in Hz. If not set the | 
|  | default frequency is 100kHz | 
|  |  | 
|  | - resets          : phandle to the parent reset controller. Mandatory | 
|  | whenever you're using the "allwinner,sun6i-a31-i2c" | 
|  | compatible. | 
|  |  | 
|  | Examples: | 
|  |  | 
|  | i2c@11000 { | 
|  | compatible = "marvell,mv64xxx-i2c"; | 
|  | reg = <0x11000 0x20>; | 
|  | interrupts = <29>; | 
|  | clock-frequency = <100000>; | 
|  | }; | 
|  |  | 
|  | For the Armada XP: | 
|  |  | 
|  | i2c@11000 { | 
|  | compatible = "marvell,mv78230-i2c", "marvell,mv64xxx-i2c"; | 
|  | reg = <0x11000 0x100>; | 
|  | interrupts = <29>; | 
|  | clock-frequency = <100000>; | 
|  | }; |
