| Hardware shutdown pin. If routed on the board, this property must be |
| present. Set to a logical 1 at boot to exit the device from hardware |
| shutdown. |

| current-limit: |
| type: int |
| default: 0xFF |
| description: | |
| Global current limit. Sets the global current control register of LED |
| driver (set table 14). Limits global current based on the following |
| formula: (840/R_ISET) * (current-limit/256). Defaults to max value |
| of 0xFF, so led output will still be enabled if property is |
| not provided. |
| |
| sync-mode: |
| type: string |
| default: "none" |
| enum: |
| - "none" |
| - "master" |
| - "slave" |
| description: | |
| This property configures the LED controller as a master or slave |
| clock device. This can be used to synchronize the output of multiple |
| LED controllers. See SYNC bits in led configuration register for more |
| information. |
