| 2 | |
| 3 | Required properties: |
| 4 | - compatible : Should be "fsl,<chip>-i2c" |
| 5 | - reg : Should contain I2C/HS-I2C registers location and length |
| 6 | - interrupts : Should contain I2C/HS-I2C interrupt |
| 7 | |
| 8 | Optional properties: |
| 9 | - clock-frequency : Constains desired I2C/HS-I2C bus clock frequency in Hz. |
| 10 | The absence of the propoerty indicates the default frequency 100 kHz. |
| 11 | |
| 12 | Examples: |
| 13 | |
| 14 | i2c@83fc4000 { /* I2C2 on i.MX51 */ |
| 15 | compatible = "fsl,imx51-i2c", "fsl,imx1-i2c"; |
| 16 | reg = <0x83fc4000 0x4000>; |
| 17 | interrupts = <63>; |
| 18 | }; |
| 19 | |
| 20 | i2c@70038000 { /* HS-I2C on i.MX51 */ |
| 21 | compatible = "fsl,imx51-i2c", "fsl,imx1-i2c"; |
| 22 | reg = <0x70038000 0x4000>; |
| 23 | interrupts = <64>; |
| 24 | clock-frequency = <400000>; |
| 25 | }; |
