-Subject: [PATCH 291/806] gpio-ir: change default pull configuration to up
-
-IR receivers like the TSOP series from Vishay and compatible ones
-have active-low open collector outputs with an internal pull up of
-about 30k (according to the TSOP datasheets).
-
-Activating a pull-down resistor on the GPIO will make it work against
-the pull-up in the IR receiver and brings the idle input voltage down
-to about 1.9V (measured on a RPi3B+ with a TSOP4438). While that's
-usually enough to make the RPi see a high signal it's certainly not
-optimal and may even fail when using an IR receiver with a weaker pull-up.
-
-Switching the default GPIO pull to "up" results in an input voltage
-level of about 3.3V and ensures that an idle state (high signal) will
-be detected if no IR receiver is attached.
