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 1044/1085] ARM: dts: Add strict_gpiod dtparam
|
|
|
|
Setting strict_gpiod disables the GPIO output persistence, such that
|
|
pins are returned to being inputs when they are released. Note that
|
|
this applies to the GPIO/pinctrl driver for the user-facing GPIOs,
|
|
not the SoC GPIOs on Pi 5.
