| 27 | + Selects the LED scan mode of the LP5812. The device supports |
| 28 | + three modes: |
| 29 | + - Direct-drive mode (by default if 'ti,scan-mode' is omitted) |
| 30 | + drives up to 4 LEDs directly by internal current sinks (LED0-LED3). |
| 31 | + - TCM-drive mode ("tcm:<n>:<order...>") drives up to 12 LEDs |
| 32 | + (4 RGB) using 1-4 scan multiplexing. The <n> specifies the number |
| 33 | + of scans (1-4), and <order...> defines the scan order of the outputs. |
| 34 | + - Mix-drive mode ("mix:<n>:<direct>:<order...>") combines |
| 35 | + direct-drive and TCM-drive outputs. The <n> specifies the number |
| 36 | + of scans, <direct> selects the direct-drive outputs, and <order...> |
| 37 | + defines the scan order. |
