1 | Broadcom Kona Family I2C | ||
2 | ========================= | ||
3 | |||
4 | This I2C controller is used in the following Broadcom SoCs: | ||
5 | |||
6 | BCM11130 | ||
7 | BCM11140 | ||
8 | BCM11351 | ||
9 | BCM28145 | ||
10 | BCM28155 | ||
11 | |||
12 | Required Properties | ||
13 | ------------------- | ||
14 | - compatible: "brcm,bcm11351-i2c", "brcm,kona-i2c" | ||
15 | - reg: Physical base address and length of controller registers | ||
16 | - interrupts: The interrupt number used by the controller | ||
17 | - clocks: clock specifier for the kona i2c external clock | ||
18 | - clock-frequency: The I2C bus frequency in Hz | ||
19 | - #address-cells: Should be <1> | ||
20 | - #size-cells: Should be <0> | ||
21 | |||
22 | Refer to clocks/clock-bindings.txt for generic clock consumer | ||
23 | properties. | ||

27 | i2c@3e016000 { | ||
28 | compatible = "brcm,bcm11351-i2c","brcm,kona-i2c"; | ||
29 | reg = <0x3e016000 0x80>; | ||
30 | interrupts = <GIC_SPI 103 IRQ_TYPE_LEVEL_HIGH>; | ||
31 | clocks = <&bsc1_clk>; | ||
32 | clock-frequency = <400000>; | ||
