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 1043/1085] pinctrl: rp1: Add strict_gpiod module parameter
|
|
|
|
Setting strict_gpiod to Y makes libgpiod and the gpiod utilities behave
|
|
as documented, i.e. pins are returned to being GPIO inputs when they are
|
|
released.
