Subject: [PATCH 0/2] Improve pwm-ir-tx precision
Date: Sun, 1 Oct 2023 11:40:28 +0100 [thread overview]
Message-ID: <cover.1696156485.git.sean@mess.org> (raw)
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.

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