From db04f0d47dd1f18cf506a7dfa00035901be328a1 Mon Sep 17 00:00:00 2001 From: Chris Morgan Date: Wed, 19 Nov 2025 16:55:24 -0600 Subject: [PATCH] dt-bindings: display: rockchip: Add no-hpd for dw-hdmi-qp controller Add an attribute of "no-hpd" for the Rockchip dw-hdmi-qp controller. This is used to describe implementations where the HPD pin is not connected or used for other purposes, such as in the RK3588S based Gameforce Ace which repurposed the GPIO for an additional face button. The "no-hpd" option was chosen to be consistent with other devices which already define this parameter for broken or missing hpd functionality.
