Broadcom iProc I2C controller
Required properties:
- compatible:
Must be "brcm,iproc-i2c" or "brcm,iproc-nic-i2c"
- reg:
Define the base and range of the I/O address space that contain the iProc
I2C controller registers
- clock-frequency:
This is the I2C bus clock. Need to be either 100000 or 400000
- #address-cells:
Always 1 (for I2C addresses)
- #size-cells:
Always 0
Optional properties:
- interrupts:
Should contain the I2C interrupt. For certain revisions of the I2C
controller, I2C interrupt is unwired to the interrupt controller. In such
case, this property should be left unspecified, and driver will fall back
to polling mode
- brcm,ape-hsls-addr-mask:
Required for "brcm,iproc-nic-i2c". Host view of address mask into the
'APE' co-processor. Value must be unsigned, 32-bit
