From: Francesco Dolcini <francesco.dolcini@toradex.com> stable inclusion from stable-v6.6.2 commit d0f5457828d441eadb61d6c0b5725e7e08e29561 category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I8IW7G Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=... -------------------------------- [ Upstream commit 664e2852aa9142193c2e241327631f032b966742 ] Keep the DPI to MIPI-DSI bridge disabled in the SoM dtsi file. The display chain is not wholly described in the device tree file, on Verdin product family the displays are additional accessories that are configured/enabled using DT overlays. With this enabled we have issues when a display is enabled on TIDSS port1 (LVDS) and port0 (DSI) is not used.
