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 0345/1085] drm/panel: Add panel driver for Ilitek ILI9806E
|
|
panel
|
|
|
|
The Ilitek ILI9806E driver is used in the Pimoroni HyperPixel4
|
|
and potentially other displays. Whilst it can support multiple
|
|
interfaces, this driver only accounts for SPI configuration and
|
|
DPI video data.
