From b1a8daa7cf2650637f6cca6aaf014bee89672120 Mon Sep 17 00:00:00 2001 From: Parth Pancholi Date: Thu, 3 Jul 2025 10:45:34 +0200 Subject: [PATCH] arm64: dts: ti: k3-am62p-verdin: fix PWM_3_DSI GPIO direction PWM_3_DSI is used as the HDMI Hot-Plug Detect (HPD) GPIO for the Verdin DSI-to-HDMI adapter. After the commit 33bab9d84e52 ("arm64: dts: ti: k3-am62p: fix pinctrl settings"), the pin was incorrectly set as output without RXACTIVE, breaking HPD detection and display functionality. The issue was previously hidden and worked by chance before the mentioned pinctrl fix. Fix the pinmux configuration to correctly set PWM_3_DSI GPIO as an input.
