Device tree configuration for i2c-ocores | ||
|
||
Required properties: | ||
- compatible : "opencores,i2c-ocores" | ||
- reg : bus address start and address range size of device | ||
- interrupts : interrupt number | ||
- regstep : size of device registers in bytes | ||
- clock-frequency : frequency of bus clock in Hz | ||
- #address-cells : should be <1> | ||
- #size-cells : should be <0> | ||
|
||
Example: | ||
|
||
i2c0: ocores@a0000000 { | ||
#address-cells = <1>; | ||
#size-cells = <0>; | ||
compatible = "opencores,i2c-ocores"; | ||
reg = <0xa0000000 0x8>; | ||
interrupts = <10>; | ||
regstep = <1>; | ||
clock-frequency = <20000000>; | ||
|
||
dummy@60 { | ||
compatible = "dummy"; | ||
reg = <0x60>; | ||
}; | ||
}; |
