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 0615/1085] drm/vc4: txp: Add byte enable toggle bit
 | 
						|
 | 
						|
The MOPLET doesn't have the BYTE_ENABLE field to set, but the TXP and
 | 
						|
MOP do, so let's add a boolean to control whether or not we need to set
 | 
						|
it.
