It stands for Device Tree. It remained this way from the previous version. In
the previous version I had modes described in an enum, to be used by PWM core,
as follows:
enum pwm_mode {
	PWM_MODE_NORMAL,
	PWM_MODE_COMPLEMENTARY,
};

and, to avoid conflict b/w these defines and the one from
include/dt-bindings/pwm/pwm.h I introduced this DT in the define names from
dt-bindings. But now the DT might be removed since I've changed the way the PWM
mode is identified in PWM core. I will remove the DT in the next version, if not
requested otherwise.

Thank you,
