From 7df6ccab5c78cf7ce92ed824a6532a3eff758195 Mon Sep 17 00:00:00 2001 From: Stephen Boyd Date: Tue, 23 Mar 2021 19:55:34 -0700 Subject: [PATCH] arm64: dts: qcom: trogdor: Add no-hpd to DSI bridge node [ Upstream commit 5f551b5ce55575b14c26933fe9b49365ea246b3d ] We should indicate that we're not using the HPD pin on this device, per the binding document. Otherwise if code in the future wants to enable HPD in the bridge when this property is absent we'll be wasting power powering hpd when we don't use it on trogdor boards. We didn't notice this before because the kernel driver blindly disables hpd, but that won't be true for much longer.
