-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
-
-Example:
- i2c0: i2c@18008000 {
- compatible = "brcm,iproc-i2c";
- reg = <0x18008000 0x100>;
- #address-cells = <1>;
- #size-cells = <0>;
- interrupts = <GIC_SPI 85 IRQ_TYPE_NONE>;
- clock-frequency = <100000>;
-
- codec: wm8750@1a {
- compatible = "wlf,wm8750";
- reg = <0x1a>;
- };
- };
