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.
Fixes: 87f95ea316ac ("arm64: dts: ti: Add Toradex Verdin AM62P")
