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. $ref: /schemas/types.yaml#/definitions/string pattern: '^(tcm|mix):[1-4](:[0-3]){1,4}$' vcc-supply: description: Regulator providing power to the 'VCC' pin.
