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 1096/1135] DTS: bcm2712: don't assume L1 sub-state support at
|
|
chip level
|
|
|
|
L1 sub-states require the connection of the CLKREQ# auxiliary signal
|
|
which is a PCB-level decision, and also depends on the vagrancies of
|
|
adapters/interposers/slots that may exist between the chip and the
|
|
endpoint.
|
|
|
|
If this parameter is present, and the RC driver sees an L1 substate
|
|
capability in the endpoint, then the result is a broken link if CLKREQ#
|
|
isn't end-to-end connected - regardless of the state of the L1.x enable
|
|
bits in the RC.
|
|
|
|
Board-specific methods (HAT+ overlay, board DTB) should define this
|
|
property if required.
