[PATCH v2 0/3] Improve pwm-ir-tx precision

[Sean Young <sean@mess.org>]

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.

changes:

v2:
 - Simplified the pwm ir tx based on Ivaylo Dimitrov suggestions
 - Renamed pwm_can_sleep() to pwm_is_atomic
 - Fix sleeping issue in pwm-bcm2835 (clk_get_rate() can sleep)
 - use non_block_start() in pwm to check atomic-ness

Sean Young (3):
  pwm: make it possible to apply pwm changes in atomic context
  pwm: bcm2835: allow pwm driver to be used in atomic context
  media: pwm-ir-tx: trigger edges from hrtimer interrupt context
