From 27da533af9b050e751a419c743096d06017daf0e Mon Sep 17 00:00:00 2001 From: Johan Hovold Date: Thu, 29 Sep 2022 18:11:24 +0200 Subject: [PATCH] clk: qcom: gcc-sc8280xp: use retention for USB power domains Since commit d399723950c4 ("clk: qcom: gdsc: Fix the handling of PWRSTS_RET support) retention mode can be used on sc8280xp to maintain state during suspend instead of leaving the domain always on. This is needed to eventually allow the parent CX domain to be powered down during suspend.
