If the boot firmware does not configure the display (e.g. because a different display is selected for output in the UEFI settings), then the display fails to come up and there are several errors in the kernel log: [drm:dpu_encoder_phys_vid_wait_for_commit_done:544] [dpu error]vblank timeout: 80020041 [drm:dpu_kms_wait_for_commit_done:524] [dpu error]wait for commit done returned -110 [drm:dpu_encoder_frame_done_timeout:2715] [dpu error]enc40 frame done timeout ... Fix this by adding the missing pinctrl for gpio119 (func1/edp0_hot and bias-disable according to the ACPI DSDT), which is defined as &edp0_hpd_default template in x1e80100.dtsi.
