1Broadcom iProc I2C controller 2 3Required properties: 4 5- compatible: 6 Must be "brcm,iproc-i2c" or "brcm,iproc-nic-i2c" 7 8- reg: 9 Define the base and range of the I/O address space that contain the iProc 10 I2C controller registers 11 12- clock-frequency: 13 This is the I2C bus clock. Need to be either 100000 or 400000 14 15- #address-cells: 16 Always 1 (for I2C addresses) 17 18- #size-cells: 19 Always 0 20 21Optional properties: 22 23- interrupts: 24 Should contain the I2C interrupt. For certain revisions of the I2C 25 controller, I2C interrupt is unwired to the interrupt controller. In such 26 case, this property should be left unspecified, and driver will fall back 27 to polling mode 28 29- brcm,ape-hsls-addr-mask: 30 Required for "brcm,iproc-nic-i2c". Host view of address mask into the 31 'APE' co-processor. Value must be unsigned, 32-bit 32 33Example: 34 i2c0: i2c@18008000 { 35 compatible = "brcm,iproc-i2c"; 36 reg = <0x18008000 0x100>; 37 #address-cells = <1>; 38 #size-cells = <0>; 39 interrupts = <GIC_SPI 85 IRQ_TYPE_NONE>; 40 clock-frequency = <100000>; 41 42 codec: wm8750@1a { 43 compatible = "wlf,wm8750"; 44 reg = <0x1a>; 45 }; 46 }; 47
