- * 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>;
- };
