| 3 | ** unittest |
| 4 | |
| 5 | Required properties: |
| 6 | - compatible: must be "unittest" |
| 7 | |
| 8 | All other properties are optional. |
| 9 | |
| 10 | Example: |
| 11 | unittest { |
| 12 | compatible = "unittest"; |
| 13 | }; |
| 14 | |
| 15 | 2) OF unittest i2c adapter platform device |
| 16 | |
| 17 | ** platform device unittest adapter |
| 18 | |
| 19 | Required properties: |
| 20 | - compatible: must be unittest-i2c-bus |
| 21 | |
| 22 | Children nodes contain unittest i2c devices. |
| 23 | |
| 24 | Example: |
| 25 | unittest-i2c-bus { |
| 26 | compatible = "unittest-i2c-bus"; |
| 27 | }; |

| 30 | |
| 31 | ** I2C unittest device |
| 32 | |
| 33 | Required properties: |
| 34 | - compatible: must be unittest-i2c-dev |
| 35 | |
| 36 | All other properties are optional |
| 37 | |
| 38 | Example: |
| 39 | unittest-i2c-dev { |
| 40 | compatible = "unittest-i2c-dev"; |
| 41 | }; |
| 42 | |
| 43 | 4) OF unittest i2c mux device |
| 44 | |
| 45 | ** I2C unittest mux |
| 46 | |
| 47 | Required properties: |
| 48 | - compatible: must be unittest-i2c-mux |
| 49 | |
| 50 | Children nodes contain unittest i2c bus nodes per channel. |
| 51 | |
| 52 | Example: |
| 53 | unittest-i2c-mux { |
| 54 | compatible = "unittest-i2c-mux"; |
| 55 | #address-cells = <1>; |
| 56 | #size-cells = <0>; |
| 57 | channel-0 { |
| 58 | reg = <0>; |
| 59 | #address-cells = <1>; |
| 60 | #size-cells = <0>; |
| 61 | i2c-dev { |
| 62 | reg = <8>; |
| 63 | compatible = "unittest-i2c-dev"; |
| 64 | }; |
| 65 | }; |
