| * Marvell MMP I2C controller | |
| Required properties : | |
| - reg : Offset and length of the register set for the device | |
| - compatible : should be "mrvl,mmp-twsi" where mmp is the name of a | |
| compatible processor, e.g. pxa168, pxa910, mmp2, mmp3. | |
| For the pxa2xx/pxa3xx, an additional node "mrvl,pxa-i2c" is required | |
| as shown in the example below. | |
| For the Armada 3700, the compatible should be "marvell,armada-3700-i2c". | |
| Recommended properties : | |
| - interrupts : the interrupt number | |
| - interrupt-parent : the phandle for the interrupt controller that | |
| services interrupts for this device. If the parent is the default | |
| interrupt controller in device tree, it could be ignored. | |
| - mrvl,i2c-polling : Disable interrupt of i2c controller. Polling | |
| status register of i2c controller instead. | |
| - mrvl,i2c-fast-mode : Enable fast mode of i2c controller. | |
| Examples: | |
| twsi1: i2c@d4011000 { | |
| compatible = "mrvl,mmp-twsi"; | |
| reg = <0xd4011000 0x1000>; | |
| interrupts = <7>; | |
| mrvl,i2c-fast-mode; | |
| }; | |
| twsi2: i2c@d4025000 { | |
| compatible = "mrvl,mmp-twsi"; | |
| reg = <0xd4025000 0x1000>; | |
| interrupts = <58>; | |
| }; |
