The previous algorithm requires that kpd_trigger_delay_us be set to 1/32 of the preferred trigger delay. The new algorithm allows setting kpd_trigger_delay_us to the preferred trigger delay directly. The actual delay can only be one of the eight levels: 2 sec, 1 sec, 1/2 sec, 1/4 sec, 1/8 sec, 1/16 sec, 1/32 sec, and 1/64 sec. The valid range of kpd_trigger_delay_us is 1/64 second to 2 seconds. A value within the valid range will be rounded down to the closest level. Any value outside the valid range will be rejected. Update board files for targets that use this driver accordingly.
