From 2af8dbd4abbfc0007dd4dabb254dcf15dcdfe73e Mon Sep 17 00:00:00 2001 From: Sean Young Date: Fri, 20 Sep 2024 11:03:25 +0200 Subject: media: gpio-ir-tx: Driver does not behave with PREEMPT_RT 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.
