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
