| * 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. |
| |
| 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>; |
| }; |
