From f6d373ff2899563ba62c7232c0a07f709adaf7b6 Mon Sep 17 00:00:00 2001 From: Johan Hovold Date: Fri, 5 Aug 2022 14:12:50 +0200 Subject: [PATCH] clk: gcc-sc8280xp: keep USB power-domains always-on The Qualcomm DWC3 driver suspend implementation appears to be incomplete for SC8280XP so keep the USB power domains always-on for now so that the controller survives a suspend cycle.
