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 0287/1085] drm/panel: jdi-lt070me05000: Use
|
|
gpiod_set_value_cansleep
|
|
|
|
There is no reason why the control GPIOs for the panel can not
|
|
be connected to I2C or similar GPIO interfaces that may need to
|
|
sleep, therefore switch from gpiod_set_value to
|
|
gpiod_set_value_cansleep calls to configure them.
|
|
Without that you get complaints from gpiolib every time the state
|
|
is changed.
