Greetings, I've noticed a regression in 6.5-rc1 that I'm having trouble bisecting between 6.4 with regards to imx8mm MIPI DSI. I'm testing on an imx8mm-venice-gw72xx-0x with the following display: - Powertip PH800480T013-IDF02 compatible panel - Toshiba TC358762 compatible DSI to DBI bridge -

Greetings, I use a standard Ubuntu 20.04 focal rootfs with a mainline kernel on an IMX6Q based board and have had no issues using things like gnome desktop, glxgears, glmark2 however recently I updated the rootfs to Ubuntu 22.04 jammy using the same mainline kernel and now I see some issues. I've

RPI 7" display touch controller

Greetings, I'm trying to get a RPI 7" touchscreen display working on an IMX8MM board and while I've been able to get the MIPI DSI display and backlight working I still can't seem to figure out the touch controller. It's supposed to have an FT5406 controller on it without an interrupt so I added
