1 * Marvell MMP I2C controller 2 3 Required properties : 4 5 - reg : Offset and length of the register set for the device 6 - compatible : should be "mrvl,mmp-twsi" where mmp is the name of a 7 compatible processor, e.g. pxa168, pxa910, mmp2, mmp3. 8 For the pxa2xx/pxa3xx, an additional node "mrvl,pxa-i2c" is required 9 as shown in the example below. 10 11 Recommended properties : 12 13 - interrupts : the interrupt number 14 - interrupt-parent : the phandle for the interrupt controller that 15 services interrupts for this device. If the parent is the default 16 interrupt controller in device tree, it could be ignored. 17 - mrvl,i2c-polling : Disable interrupt of i2c controller. Polling 18 status register of i2c controller instead. 19 - mrvl,i2c-fast-mode : Enable fast mode of i2c controller. 20 21 Examples: 22 twsi1: i2c@d4011000 { 23 compatible = "mrvl,mmp-twsi"; 24 reg = <0xd4011000 0x1000>; 25 interrupts = <7>; 26 mrvl,i2c-fast-mode; 27 }; 28 29 twsi2: i2c@d4025000 { 30 compatible = "mrvl,mmp-twsi"; 31 reg = <0xd4025000 0x1000>; 32 interrupts = <58>; 33 }; 34 35 * Marvell MV64XXX I2C controller 36 37 Required properties : 38 39 - reg : Offset and length of the register set for the device 40 - compatible : Should be "marvell,mv64xxx-i2c" 41 - interrupts : The interrupt number 42 - clock-frequency : Desired I2C bus clock frequency in Hz. 43 44 Examples: 45 46 i2c@11000 { 47 compatible = "marvell,mv64xxx-i2c"; 48 reg = <0x11000 0x20>; 49 interrupts = <29>; 50 clock-frequency = <100000>; 51 };
