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 0827/1085] pinctrl: bcm2712: Fix for sparse GPIOs
|
|
|
|
BCM2712D0's sparse GPIO map revealed that it is not safe to treat
|
|
group_selector as the GPIO number - it is an index into the array of
|
|
pinctrl_pin_descs, and the "number" member says which GPIO it refers to.
