openwrt/target/linux/bcm27xx/patches-6.6/950-1030-overlays-Force-IRQ-pins-to-inputs.patch
Álvaro Fernández Rojas 8c405cdccc bcm27xx: add 6.6 kernel patches
The patches were generated from the RPi repo with the following command:
git format-patch v6.6.34..rpi-6.1.y

Some patches needed rebasing and, as usual, the applied and reverted, wireless
drivers, Github workflows, READMEs and defconfigs patches were removed.

Subject: [PATCH 1030/1085] overlays: Force IRQ pins to inputs
Requesting a GPIO as an interrupt source does not automatically make it
an input (or even a GPIO pin). Add the necessary pinctrl nodes to the
overlays that don't already do this.
See: https://github.com/raspberrypi/linux/issues/6106
