Run configurable PWM groups. Channels in one group run concurrently,

The header defines PWM_TC_GROUPS and PWM_TC_GROUP_COUNT. Keep the
|

default for the built-in example, or provide a board-specific header

from a compiler include path. Channel enable switches, device names,

channel numbers, output modes, and waveform points are kept in that

header because Kconfig cannot represent dynamic group/channel arrays.
