From 1616877626228a6ef05ddae4017c9b0f65803a8b Mon Sep 17 00:00:00 2001 From: Stephan Gerhold Date: Fri, 22 Aug 2025 11:29:01 +0200 Subject: [PATCH] arm64: dts: qcom: x1e80100-qcp: Add missing pinctrl for eDP HPD At the moment, we indirectly rely on the boot firmware to set up the pinctrl for the eDP HPD line coming from the internal display. 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.
