PWM_POLARITY_NORMAL is not part of the DT ABI. The third cell of the specifier is a bitmask of flags. PWM_POLARITY_NORMAL is an enumeration value that evaluates to 0, so it makes absolutely no sense as a flag. PWM signals are considered to be "normal" by default, so no flag is necessary to specify that. Thierry
