    1 Broadcom iProc I2C controller
    2 
    3 Required 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 
   21 Optional 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 
   33 Example:
   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         };
