   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";
