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 0698/1085] arm: dt: add dtparams for PCIe reset timing
|
|
override
|
|
|
|
The Pi 5 variant gets two parameters so that the CM4-compatible
|
|
name will also work on Pi 5.
