| 2 | |
| 3 | Required properties: |
| 4 | |
| 5 | - compatible: should be "brcm,brcmstb-i2c" or "brcm,brcmper-i2c" |
| 6 | - clock-frequency: 32-bit decimal value of iic master clock freqency in Hz |
| 7 | valid values are 375000, 390000, 187500, 200000 |
| 8 | 93750, 97500, 46875 and 50000 |
| 9 | - reg: specifies the base physical address and size of the registers |
| 10 | |
| 11 | Optional properties : |
| 12 | |
| 13 | - interrupts: specifies the interrupt number, the irq line to be used |
| 14 | - interrupt-names: Interrupt name string |
| 15 | |
| 16 | Example: |
| 17 | |
| 18 | bsca: i2c@f0406200 { |
| 19 | clock-frequency = <390000>; |
| 20 | compatible = "brcm,brcmstb-i2c"; |
| 21 | interrupt-parent = <&irq0_intc>; |
| 22 | reg = <0xf0406200 0x58>; |
| 23 | interrupts = <0x18>; |
| 24 | interrupt-names = "upg_bsca"; |
| 25 | }; |
