| * 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>; |
| }; |
