From d1b871dd5488e53a92b3948e731154375e96a8ba Mon Sep 17 00:00:00 2001 From: Visweswara Tanuku Date: Mon, 6 May 2024 06:20:42 -0700 Subject: [PATCH] ARM: dts: msm: Ignore dependencies on children by PM framework Change https://lore.kernel.org/all/20230525113034.46880-1-tony@atomide.com registers serial core controller as a child of msm uart device. Since child should suspend first, due to the child's auto suspend delay (SERIAL_PORT_AUTOSUSPEND_DELAY_MS), additional 500msecs delay is added during msm_geni_serial_runtime_suspend. Added new dtsi flag 'qcom,suspend-ignore-children', to ignore dependencies on children by runtime PM framework, this helps to exit quickly from msm_geni_serial_runtime_suspend and save power.
