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 0802/1085] bcm2835-virtgpio: Update for Linux 6.6
|
|
|
|
The gpio subsystem is happier if the gpiochip is given a parent, and
|
|
if it doesn't have a fixed base gpio number. While we're in here,
|
|
use the fact that the firmware node is the parent to locate it,
|
|
and use the devm_ version of rpi_firmware_get.
