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 - ATTINY based regulator used for backlight controller and panel enable I'm using a dt overlay to support this [1] which works on 6.4 but on 6.5-rc1 I get the following error: [ 6.110585] samsung-dsim 32e60000.dsi: xfer timed out: 29 06 00 00 64 01 05 00 00 00 [ 6.326588] tc358762 32e60000.dsi.0: error initializing bridge (-110) I'm trying to bisect this for some reason. Does anyone have any idea what may be causing this or how I can debug it?
