Dmesg reveals the following information: [ 13.283052] mipi-dsi 1f00118000.dsi.0: deferred probe pending: mipi-dsi: supplier 2.reg_bridge not ready [ 13.283060] platform 1.panel_disp: deferred probe pending: platform: wait for supplier /axi/pcie@120000/rp1/i2c@88000/reg_display@45 The problem could be traced back to a missing I2C Driver.

Local build of armbian bookworm minimal and test if DSI display works [OK] kernel linux-bcm2711-current [fail] kernel linux-bcm2711-edge [fail] kernel linux-bcm2711-legacy Both edge and legacy images failed to build, but the failure seems unrelated to the change.
