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