[PATCH] media: gpio-ir-tx: Driver does not behave with PREEMPT_RT

From: Sean Young
Date: Sat Sep 21 2024 - 15:17:48 EST


This driver bit-bangs a signal with interrupts disabled. The signal can
last for up to half a second (IR_MAX_DURATION).

A much better way of transmitting IR is using the pwm-ir-tx driver,
which does not disable interrupts.

Say Y if you want to a GPIO based IR transmitter. This is a
bit banging driver.
