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 0964/1085] dtoverlays: Fixup pendown gpio polarity for ads7846
|
|
users
|
|
|
|
The driver has been converted to use gpiod, which will normalise
|
|
polarity based on DT.
|
|
|
|
The piscreen overlay (and others) incorrectly defines the pendown
|
|
GPIO as being ACTIVE_HIGH (0), althought triggering on the high-low
|
|
edge for pen down. It therefore tries reading the pen position when
|
|
not being touched, and stops when it is touched.
|
|
|
|
Tested with piscreen and ads7846 overlays. Also fixed on others
|
|
where the interrupt says high->low but the polarity was ACTIVE_HIGH.
