Broadcom stb bsc iic master controller
|
|
|
|
Required properties:
|
|
|
|
- compatible: should be "brcm,brcmstb-i2c"
|
|
- clock-frequency: 32-bit decimal value of iic master clock freqency in Hz
|
|
valid values are 375000, 390000, 187500, 200000
|
|
93750, 97500, 46875 and 50000
|
|
- reg: specifies the base physical address and size of the registers
|
|
|
|
Optional properties :
|
|
|
|
- interrupt-parent: specifies the phandle to the parent interrupt controller
|
|
this one is cascaded from
|
|
- interrupts: specifies the interrupt number, the irq line to be used
|
|
- interrupt-names: Interrupt name string
|
|
|
|
Example:
|
|
|
|
bsca: i2c@f0406200 {
|
|
clock-frequency = <390000>;
|
|
compatible = "brcm,brcmstb-i2c";
|
|
interrupt-parent = <&irq0_intc>;
|
|
reg = <0xf0406200 0x58>;
|
|
interrupts = <0x18>;
|
|
interrupt-names = "upg_bsca";
|
|
};
