Required properties:
- compatible:
- Must be "brcm,iproc-i2c"
+ 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
-- interrupts:
- Should contain the I2C interrupt
-
- clock-frequency:
This is the I2C bus clock. Need to be either 100000 or 400000
- #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
+
Example:
i2c0: i2c@18008000 {
compatible = "brcm,iproc-i2c";
