[0/2] Improve pwm-ir-tx precision

Message

The pwm-ir-tx driver has to turn the pwm signal on and off, and suffers
from delays as this is done in process context. Make this work in atomic
context.

Sean Young (2):
  pwm: make it possible to apply pwm changes in atomic context
  media: pwm-ir-tx: trigger edges from hrtimer interrupt context
