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 1082/1085] pinctrl: rp1: Use persist_gpio_outputs
|
|
|
|
Following 8ff05989b44e1a8f7d2bbe67320990ebc2fbb5e5, adopt the same
|
|
parameter name but with the opposite default.
